Misc exterior paint questions
Hi,
I have a stucco house with a rough finish thus backrolling is a must from what I'm reading. I don't understand if when backrolling are you adding paint to the roller? Obviously you are not starting with a dry roller but are you adding any paint to the roller as you go along?
And this begs the question, what is disadvantage of just rolling? You don't have to mask windows. On a 2 story house I suppose it may be a bit awkward to load the roller. I did an interior wall once with 18' high ceilings and I had to switch from a long handle roller to short and I guess I took too long because I can see the horizontal line where I switched over - the sheen is different in a grazing light. Is this the danger of rolling very large/tall surfaces? Is it difficult to work fast enough that you maintain a wet edge?
Also, I would like to roll some test patches on the wall but have not pressure washed yet. Can I clean the wall area with a scrub brush + lightly soaped water, rinse and wait a few days before rolling on a test patch?
Thanks

Whenever you spray a coating on most any substrate other than steel - it should be back rolled! Back rolling works the paint into all the crevices resulting in a better looking, longer lasting paint job. Many times stucco is just painted with a brush and roller. Spraying is quicker and cuts out a good bit of the brush work but it still needs to be rolled. For the most part the roller is half full of paint and you are just working it into the stucco. I've painted many stucco houses where it wasn't prudent to spray - you always have to be mindful of where the over spray will go!
You don't have to use a pressure washer. The main thing is to remove any grime/mildew along with any chalk. Paint doesn't adhere long term to chalky surfaces. When it can't be washed off you need to either use an oil base masonry conditioner or add Flood's EmulsaBond to the 1st coat of latex.
