Brush or Roll?

We're getting ready to paint the exterior of our home. Is it better to brush or roll? Also wondering what is the best product to use for power washing the house? We have a couple of places where there is mildew and want to make sure that doesn't come back. We'll be priming everything prior to painting.

If it were my house I'd spray it, back-rolling if necessary. The airless sprayer will do a better job of applying the paint the the surface and be much faster. Back-rolling is where once the paint is applied, you run a roller across the surface to force the paint into nooks and crannies. Sometimes painting from multiple directions will prevent the need to back-roll, just depends on how rough the surface is.

As for the mildew, I'd spray it with a bleach solution, let it sit for a while, then wash the area down again.

On my own home, I used a roller followed by back brushing. I have Hardi-Plak horizontal clapboards. A 7 inch, half inch nap roller just fits the lap reveal. I feel that the physical brushing of the paint, whether sprayed or rolled, adds to the bonding of the new paint to the old paint strata.

As to cleaning the house, every house I ever painted was first power washed after injecting a bleach/soap solution onto the house. The typical house would use between 4 to 6 gallons of bleach. I would top off the bleach bottle with Ivory diswashing liquid and then syphon directly from the bottle. Ivory is a mild soap and not a harsh detergent. Products such as TSP can actually damage some surfaces, The Ivory would also foam up when sprayed, assuring me that where ever I saw the foam, I knew that I had hit with the bleach too.

If we are using brush that can wasting your times..., but that can reach a difficult part is done with the roll..

If using roll you can save your times, but need much paints. Cause the roll absorb your paint too...

If you wanna use sprayer the result is not equal layer, in other part thin and other thick...

But the important think you must know quality of your paint, your building/surface, and equipment...

Spray with a good quality paint sprayer like a Titan 440. I've owned one for ten years and you can cut your time by a factor of ten. There is never a reason to back brush or back roll after using a paint sprayer. You will just ruin the perfect finish the sprayer will put on the surface. Home Depot and other rental places rent paint sprayers. You should be properly prepared before you rent by buying a paper masker. These cost about $25 at Sherwin Williams or other good paint store. This a a huge labor saver. It actually takes me more time to mask a house with a paper masker then to apply a prime coat and finish coat.

If you have never used a paint sprayer before practice on a piece of plywood or on the back side of your garage before you start on your house. Do the back side first until you feel competent. It is also much safer. Even if your house is one story you will still be on a ladder to paint the higher portions. When you spray with a quality paint sprayer your pick up tube is sitting in a five gallon bucket on the ground and you can spray with one hand and hang onto the ladder with the other hand. No more balancing a can of paint on a ladder.

Re: Brush or Roll?

Thanks for the good advice. My husband is a die hard believer in having to brush a house to paint it. I'm thinking I'd like to have this job done before winter!! We have a tri-level home, so it's 2 stories and lots of ladder work will have to be done. Spraying sounds not only faster, but much safer. Wish me luck on trying to talk him into doing it with a sprayer. We actually have one that one of my sons got me for Christmas one year, but it's never been used...go figure!

Re: Brush or Roll?

I am currently painting the exterior of my home. It is masonite. I bought a nice, heavy paint with UV protection, primer, and mold/mildew resistent. It is a one-story house and I can reach the areas I need to get to on a step ladder. I decided to do the brush-and-roll. I use a 2" brush to make sure I get all the areas that are too small for a roller to reach. I basically brush the paint on all areas of the masonite. After that dries, I go over it with a roller brush. I tried the thicker roller pads and just made a mess of things by overloading the pad, etc. I am now using a regular roller pad and I am actually using a shorter roller instead of the regular sized roller. For me, it ensures I am reaching all the necessary areas and getting the entire surface area covered. I am painting a light gray house to a "sage" green so any missing paint areas tend to show up very well. The roller helps to finish off the paint job and I think it makes the area look much more "expensive". The brush alone tends to leave uneven color and it is easy to miss areas since the masonite is textured. It may take longer, but I think the time is worth it. I have to paint on days off, etc., so I can't just start and work until I am finished. I also used a flat finish. I am happy with the results and my neighbors have actually told me they are impressed with the color as well as the paint job!! :)
