Painting rooms 101

January 16, 2009

Copyright 2005 - www.360clips.com

Question:

I am a first time home owner and I plan on painting some rooms. I’d like help from you. Can you provide the dos and don’ts and gotcha’s I have to look out for.

1. What brand of paint should I go for? Big home improvement store or a local paint store?
2. What types of brushes will I need and how many?
3. What other tools should I arm myself with?
4. How many coats of paint is right to get the right shade?

thanks in advance
RC

Answer:

Hello Ryan,

1) There is no right answer for home improvement store paint or local paint store. The fact is this… each company makes one of two great products and everything else generally performs the same with the exception of the Zinsser Company. Zinsser makes all great products but more geared towards specific applications and a wide range of primers and sealers. There are good products sold at both places but few. You may be able to find the exact product at both places.

Paying $30-$40 or even $50 for a gallon of paint does not mean it is quality paint at all. You would be surprised. One of my favorite wall paints is sold at a box store and that same product is re-labeled and sold at a paint store, two separate prices. Obviously, I opt to save money.

2) You want one or two paint brushes for painting walls in bedrooms and around the interior of a home. A quality nylon/polyester blend is suitable for most acrylic paint. Choose a 2.5” angular sash brush and a 3” flat paint brush for cutting ceiling lines and longer runs like the top of baseboard. I suggest a brush without flagging. Choose a paint brush that is chisel tipped and tapered for a sharp, clean accurate cut.

3) You might want to purchase a 5-in-1 tool, it will come in handy throughout the year. You will need plastic or drop clothes or both, masking tape and rags.

The list:

Step ladder, deep-well roller pan, a 5 wire heavy gauge steel roller frame, an 2’ – 4’ extension pole will save you time and reduce fatigue and get you up to 9’ ceilings. Use a quality white woven roller cover. I recommend a 1/2” or 3/8” roller cover for smooth to lightly textured walls. A single edge break-away razor for scoring the masking tape prior to pulling the tape off the trim and molding. You may need a hammer to remove nails and some spackling or drywall mud and a knife to spread it with to repair any imperfections.

4) Most paint covers good in 2 coats so I would at least plan for that. The more intense wall colors often require 3-4 coats and sometimes more and some require a specific primer. Ask the representative at the place of purchase how many coats should the paint cover in.

Do not purchase cheap inexpensive roller covers, expect to pay close to $5 for one. Almost all roller covers shed fibers but the white woven covers shed the least if at all. Purchase a brush that will last throughout the years. Take care of it. A quality brush will save you time and make painting a whole lot easier.

Drywall primers… again!

December 20, 2008
DSC_3833aI receive countless emails asking when to use a drywall primer with all the talk today about self-priming wall paints. Many paint contractors commented on my videos on YouTube saying I should use a wall primer on bare drywall rather than applying wall paint directly over it. What do they know that I don’t? So let’s take a closer look at wall primers and their purpose. What is a wall primer supposed to do? (Click any photo for larger views).

Bare Drywall

IMG_0078The objective priming bare drywall is to seal the porous paper and drywall topping (mud) to provide a nice foundation for the paint to bond with. What this means is achieving an ultimate seal and bond with the paint to the porous fibers of the paper and the porosity of drywall mud. We also want the wall primer to produce a solid uniform sheen for the top coat of paint.

Our goal has four parts:

1) seal the porous paper surface
2) provide a surface the paint can bond with
3) seal the drywall mud
4) prevent top coat sheen degradation

What can go wrong using primer:

What if the top coat of paint did not bond with primer? What if the primer didn’t bond with the drywall? What if you had a nice bond to the drywall but not to the drywall mud? What do you do now? You primed right? The paint isn’t sticking that well is it? Did you try the tape test or maybe you tried washing it and the paint and primer came off back to bare drywall? Did you remove the masking tape from the baseboard and it tore the paint and primer off the wall exposing bare drywall?

The label on the paint can says to use a primer. The paint store rep said to use a primer. You read online, you read it in a magazine, you always heard – ‘use a primer’ and you did. You even used the paint manufactures recommended primer.

So now what? Is it too late; you already have a coat of paint over the primer? Was the surface clean? Did you remove all the drywall dust left behind from sanding? Did you shop vac the walls and the paint still didn’t stick? Did you try wiping down the drywall with a damp sponge? Yeah, so did we. Did the primer fail? Yeah, so did ours. Did you do something wrong?

Lucky for you, we have all the answers and before you get discouraged we also have a fix so you can achieve that finish and bond that you initially tried for.

We tested a total of 14 wall primers over bare drywall and not one of them performed as well as a drywall sealer such as Zinsser Gardz. Let’s take a look at why this is.

The Test

2paintYou perform the test yourself. Let’s say for example you have a piece of bare drywall sitting on your lap and 1 tablespoon of water and 1 tablespoon of any wall primer of your choice, there are tons of them out there, pick one. Now, take the tablespoon of water and slowly pour it on the drywall. The water dissipates into the drywall right? Now take the tablespoon of primer and do the same. Not exactly the same result huh?

If you want to dive deeper into testing, try this test over bare drywall mud, it will provide similar results with a completely different effect with the primer.

Do this small test too. Take a sanded drywall patch, clean it, dust it, vac it, damp sponge it if you want and run your finger over it when its dry. I suspect your finger will have a white dusty powder on it.

So what does this test tell us? No matter how well you clean up new board for paint there is only one thing that will prepare it to accept paint. Apply a sealer that will penetrate both the paper and the mud and bond all of it together. Thinner material penetrates better – right?

Click the photo above. Notice the first 24" inches from the corner doesn’t look as nice as the next 24", then you see another 24" that doesn’t look as nice as the 2nd area. That 2nd area that looks best in the photo is 2 coats of eggshell paint over bare drywall. The first 24" is primer plus one coat of eggshell paint.

Sheen degradation

One huge set-back you get from using a primer is top coat sheen degradation. Some primers are better than others but nonetheless, you will lose some sheen that will get absorbed in the primer coat. The loss of sheen is very apparent in the photo above.

proform004Here is a photo of a drywall sealer applied directly over the drywall mudded horizontal seam. You can clearly see how well the sealer absorbed into the mud. The next photo shows what the horizontal seam looks like when you apply one coat of an eggshell paint over it.
proform005Again, you can clearly see the sealed portion of the wall and what was not sealed.

 Primer vs. Paint

Img00970001Think back to a time you applied a coat of paint over bare wood. Do you remember what happens with the paint? Do you recall how much of that paint absorbed into bare wood? Do you remember applying a second coat of paint and it too absorbed into the bare wood, even your third coat looked questionable? (Click any photo for larger views)

Well check this out… the same thing happens when you apply paint over bare drywall. Exactly the same thing but with varied results depending on the paint you use.

There are paints that penetrate bare drywall better than a primer and provide a better bond and also look great when you apply 2 coats over bare drywall. So here we have a classic case of Best, Better and Good options.

The photo above shows a coat of paint over bare drywall (the darker color). The window wall and into the corner is a tinted primer. So you can clearly see some finish paints perform nicely over bare drywall with coverage. The paint used in the above photo outperformed all 14 primers in coverage over bare drywall. How messed up is that? – paint performing better than a primer designed for bare drywall.

Looking at the photo above, would you honestly say a primer is needed over bare drywall if I can achieve both coverage and tight bond with a paint that is far better than if I used a primer? I’m saying… knock yourself out. If you feel that you have the desire to waste money and labor on a primer coat, then do it.

But let’s take a look at what is best because that’s what this site is all about.

Best

eggshellThe best product known to me for bare drywall is Zinsser Gardz and thankfully we have that product because it makes me never want to use a wall primer again. I say this because I see primers fail all the time, hence the abundance of people writing me about primers. Apply Gardz directly over bare drywall and then for best results – 2 coats of paint. Remember this is new board and you need to build a foundation so use 2 coats of paint. Think about this, even with one coat of Gardz, and 2 coats of paint, your total dried mil thickness is still minimal at best.
gardz2Gardz is a thin clear sealer and most of the product will dissipate into the fibers of the board and mud. This product is similar to injecting glue into the drywall and mud. This is why in the photo above you see a very nice uniform finish with one coat of Gardz and one of finish.

Better

UH1412_01aBecause there are paints that I know adhere better than all 14 primers we tested I am going to say straight quality paint is better over bare drywall. The only problem you may experience is a need for a 3rd coat – prime plus 2 coats is a total of three coats anyway but you can achieve better stick this way. Ok, to be fair the other argument to this method is achieving a uniform finish with paint like an eggshell or semi gloss. But think about this, 1 primer and 2 finish is 3 coats too.

In the photo above the long wall is split half way with two different wall paints and the photo was taken after they dried. Notice in the front most left portion how one product covered and dried much nicer than the other closer to the window.

Good

barrington 24 027aThe cheap and less expensive route is using a primer over bare drywall. You have an advantage utilizing this method but it also disadvantages. The advantages are – you can do one tinted coat of primer and one coat of finish but you lose the stick or bond some of us need to tape off walls, hang wallpaper over and even wash or scrub depending on what your paint allows.

Remember when you got the job, she told you she was hanging wallpaper at a later time. So, do you shortcut her at this point or prepare the job for what is to come? What if its you hanging that paper? Too many guys are doing the "right-for-now" work instead of what is best for down-the-road work.

Primer is generally less expensive than paint. So if your intent is to never wash or touch the walls then do this method but what you might find is what you see in the photo. It looks like it needs another coat of paint.

Primer also requires MORE attention to rolling than wall paint. If you roll primer on any old way – you will never get the finish to look right no matter how many coats you stick on it. Here is a clip on rolling. Utilizing the last stroke down method will provide a level of finish that is consistent. The finish in the Best Method was done with last stroke down.

Something to think about

Here is something else to think about for those of you shooting commercial work. Think about how much you can save on materials utilizing a better method. What is that high-build primer suppose to be shot at??? 20 mil thick? That is crazy!!! Actually its ridiculous. If you are shooting walls – you are already wasting materials and damn near twice as much vs rolling it on.

Here is an interesting tid bit. Same two houses done two different ways. One guy sprayed the walls with 60 gallons and the other rolled it with 15. The guy spraying had a guy back rolling too. What a huge waste of time and money and an extra guy. Guy spraying spent $1,380 on materials and the guy who rolled it spent $345 There was no difference in workmanship.

Funny how a certain manufacturer makes an executive decision to create a primer that requires such a heavy layer of it to cover bare drywall. But that same question also begs the question, was a product like that designed because guys don’t know how to paint or does the manufacturer not know how to make a product that works without laying it on so heavy. If you apply anything at 20 mil, it better look good!

The argument

440i My argument with using a wall primer is the lack of a fail-safe method and I need that in my business. While I enjoy the 440i I received from a paint store due to primer failing, I am not going to have another homeowner come back to me complaining she washed the paint and primer off the wall and obviously this has happened to me otherwise I wouldn’t be posting a fix to this problem online. I have a ton of information and previous test on wall primers. Do a Google search on jackpauhl+wall primers or click this link.

The Fix

So let’s say you too fell sucker to the “use a primer” method and you are in that same situation where the paint washes off the wall or you had to apply masking tape to do some wild painting scheme you found on TV. There is a fix and leave it to no other than Zinsser to have your back! Zinsser Gardz can be used to apply over a paint that was previously undercoated with primer utilizing the Good method above. Gardz will assist with penetrating the paint and the primer and help with bonding them to the drywall beneath and not only that but moving forward with a new coat of paint will give you the ultimate finish you see in the Best method above.

Painting highly visible walls

Let’s say you get a call and their house is a few years old with builder grade flat paint on the walls and they want you to paint the 16′ high foyer wall that extends to the back of the house (windows on both ends). You go to the basement and see the left over paint and know putting an eggshell over that flat paint might require a certain degree of finesse to make a highly visible wall look right. Your best bet here is to apply Zinsser Gardz over that flat and proceed with one or two coats of eggshell paint.

Common Painting Myths

December 19, 2008

busted When I first posted my painting videos online there were only two other videos online, today, there are countless videos and paint related articles online.

Its unfortunate there is so much misinformation at everyone’s fingertips online (some of those videos people post make me cringe) and much of what I read is that same misinformation republished even in trade magazines over and over, same boring virtually meaningless stuff. But if you think about it, many of the people writing are getting their information online rather than from experience.

If you are a professional painter like me then you too are probably familiar with the misinformation. You want information beyond your current knowledge both with product and with acquired skills. You want to seek out something new, something you don’t already know that can benefit your business. For those new to the painting business, misinformation might send those readers on a costly expense of learning the truth the hard way. This is where the information on this blog becomes such a huge resource of information. I didn’t find this information anywhere online, I write about my real in-the-field applications, methods, products and experience. The information here isn’t secondhand and copied from various unreliable sources. There is no ‘grapevine’ effect.

Here are just a few myths busted on painting. I will try to add to the list for those who write in asking about things they read online or elsewhere. You have every reason to question it and validate it.

1) An Illinois-based decorating company wrote along these lines: Without the correct brush, it won’t lay out a nice finish. This is not true at all. What he is trying to explain has little to do with the brush and more to do with product. I can provide you with an ultra smooth finish using a whisk brush that people use to sweep up into a dust pan.

2) The same guy recommends Ox-hair or hog-bristle China brushes for applying oil-based product, but he says they can’t take the abuse of waterbornes. This was true years and years ago (more than 10 years ago). Now synthetic brushes far outperform china when spreading not only vanishes, sanding sealers and polys but also oil-based paint and even primer. Some perform better with stains both oil-based and waterborne.

3) It is said that nylon is soft, allowing paint to lay down smoothly, and cleans up easily. He recommends nylon bristles for woodwork and other areas that require a smooth finish”. Nylon is recommended for applying clears or painting over highly textured surfaces. The term "nylon" doesn’t mean you get a smooth finish at all.

4) He goes on to say the down side to nylon bristles is clogging easily, especially when used with fast drying paints. He believes for this reason, many brushes contain a blend of nylon and polyester”. I never heard anything about nylon clogging up. This sounds like poor pre-prepping a brush and or brush-work-style or methods and or poor product. I have no idea what that statement means. I do know however that polyester was added to a nylon brush for firmness and bend recovery purposes which he mentioned later. Polyester is not the culprit of brush marks, its one of four other things, 1) tipping, 2) flagging 3) product, 4) application.

5) A manager from a Sherwin Williams store in MO says the brush size matters: he explains cutting in with a dark color against a hard surface usually requires the precise edge of a “thin” brush. Thin has nothing at all to do with sharpness and an ability to cut an edge but everything to do with tipping. A 5/8” brush can be just as sharp as a 15/16” brush. Cutting sharp edges are in fact done more easily with a wider brush due to its fingerprint and stance on the wall provides more stability vs a thin brush.

6) He goes on to say thicker brushes are recommended for cutting in between a heavily textured wall and ceiling. Not quite. A heavily textured wall requires two things, first a soft nylon only brush and 2) the thicker the better. A firm thick brush will do no good on a “heavily textured wall and ceiling”.

7) He adds, there are regular brushes that have flagged bristle which he explains will hold more paint than a tipped bristle but won’t cut as fine a line. There is no such thing as a “regular” brush and flagging and tipping has absolutely nothing to do with how much paint a brush can hold.

8) And as if that wasn’t bad enough he says the fuzzy endings of flagged brushes are also better at eliminating brush strokes than finely pointed, tipped brushes. Not true at all. Flagged bristles are notorious for leaving brush marks despite brush manufacturer’s efforts to reduce the amount of brush marks. Fine tipped bristle is anyone’s best chance with any product to achieve smooth finishes.

Load Balancing

December 13, 2008

superfab What is Load Balancing?

Years ago I conducted a study on how far various roller covers can carry a load of paint. You can see an example in the photo. I wanted to know how much more distance can I get out of all the 1/2" covers available to me and find the best one. Then I wanted to compare the 1/2" covers against 3/4" covers of the same brand to see how much more distance I can get using a 3/4" cover assuming a desired roller texture. The same study was conducted on brushes.

Load balancing is gauged on the capacity of the brush or roller and the amount of paint you load them with for optimum results. Each load (amount of paint) is predetermined before taking the load based on for example where it will be placed on the wall or trim.

Load Balancing is one of the more important aspects with efficient painting. It’s a combination between the right paint brush or roller and the amount of paint in which you load them and how it impacts performance more than anything else.

Load Balancing allows me to paint ridiculously fast because each (next move) or next load of paint is thought out. What this does is eliminates unnecessary brushwork and/or more effective results with each load of paint.

In the video where the side of the casing is painted in about 8 seconds, Load Balancing plays a huge role in allowing me to do that. 1) The brush needs to be capable of holding a load of paint to go the distance of 7’. 2) I also need to know how much paint I will need to travel 7’ and put that amount of paint on the brush.

Look for more on this topic soon along with video demonstrations. For now you can see more on this topic here.

Suck Less at Painting #101

HowTO: Freehand Cutting against any single edge source.

cut-in006

We are using a 2.5" angular Benjamin Moore paint brush for this demo. Start by loading the paint brush. It helps to pre-wet the brush with water prior to painting, squeeze or kick it out. This will help keep paint from drying on the brush and will assist with cleaning the brush later. Be sure the brush is loaded about 1.5" up the brush as seen in the photo above.

cut-in004

Start by applying light pressure on the rim of the can to remove the paint from the right side of the brush but leave about 1/2" to 3/4" of paint as seen in the photo on the left. The photo taken after the paint was removed on the right side of the brush. Click any photo for larger view.

cut-in001

Your paint brush should look like this on the right side and bottom as seen in the next photo below.

cut-in002

Paint on right side and a bit on the bottom.

cut-in003

Flipping the paint brush over, here is the left side with all paint removed from this side because this is the side (edge) that will cut against your source object such as a casing or a ceiling line that you do not want wall paint on.

cut-in007

Do not paint like this with the paint brush flat against the wall. Also pay attention to how to hold the brush in the photo above.

cut-in008

Hold the brush like seen in photo and make your first pass above the object. Remember your paint is on the opposite side of the paint brush not the side near the wood.

cut-in009

Make your next pass cutting-in closer and tight to the wood. If necessary, wipe the brush lightly on the rim of the can before this final pass. The paint you need is already on the wall, Your second pass only needs to move it closer to the wood. You can see the full video from YouTube below.

How paint increases humidity

November 7, 2008

IMG_0728a

This is just an FYI piece.

The project was to paint one 12×12 room with one coat of paint. I took a humidity reading prior to starting and again when finished. The humidity in the room before I started was 44% so as you can see just how much humidity painting one room with the door open can increase. In just 7 minutes of rolling the walls, the humidity jumped 14%.
