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.

Brush Handle Mod

April 29, 2007

Take more control of your brush. This simple modification to the handle will better assist your cutting accuracy by placing your thumb more securely on the handle instead of pivoting on the edge. The placement of my thumb rarely moves when I cut casings and trim so this is where I decided to make the thumb support. The only time I notice a repositioning of my thumb is in some situations on a ceiling line.

I used a rounded wood file and wrapped sandpaper around a piece of 1 ¼” PVC to smooth it up.

Painting Poplar

April 13, 2007

Poplar trim is often used in the new home market alongside man-made hybrid trim products such as finger-jointed pine or MDF (Medium Density Fiberboard). Poplar is a difficult wood to achieve gloss finishes on due to its porosity which acts like a sponge. Oil-based primers are recommended over latex primers for poplar. Generally one coat of an oil-based primer and 2 coats of acrylic semi-gloss paint will not produce a uniform gloss appearance.

One solution for producing nice results on poplar is using two coats of primer and two finish coats. I recommend an oil-based primer such as Zinsser Bulls Eye High Hide Odorless. Apply a slightly reduced coat of primer to the bare wood and let dry, then sand thoroughly. The reduced coat will allow the primer to penetrate the wood fibers better, raising the grain nicely to sand smooth with intent to remove any brush marks.

The second coat of primer will provide a solid undercoat for gloss finishes. If the first coat of primer is properly sanded, the second coat of primer may only need a very light sanding.

Priming Bare Wood

April 7, 2007

Successfully priming bare wood is important for three reasons. The first is to seal the wood by preventing moisture from absorbing in the wood, to protect it. The second is to provide a clean fresh surface for finish paint to bond. The third, to provide a base coat preventing the finish paint from being absorbed into the wood.

Ever wonder how the professionals achieve those high gloss finishes or iridescent-like semi-gloss finishes? Professionals will often apply two coats of primer and at minimum two coats of finish.

Use a solid oil-based high-hide primer such as Zinsser Cover-Stain found at most hardware or home stores. Cover-Stain can be finish coated in 2 hours and sticks well to all surfaces without sanding.

When priming bare pine wood, a light sanding prior to applying the finish coat is all that’s required to achieve nice results. Poplar wood is a different story; poplar wood is very absorbent of paints. It acts as a sponge. The best way to achieve professional results on poplar is to apply two coats of primer and two coats of finish, sanding the first primer coat more heavily than the second. For best results, wait 4 hours for primer to dry, then sand.

TIPS
– use Zinsser Bulls Eye High Hide Odorless primer for poplar, you may be able to skip 2 coats of primer

– use a black china bristle brush for applying oil-based primers. Some synthetic brushes can also be used.

– oil-based primers require mineral spirits (thinner) for clean up.
