Back to the article. You can add water to all latex based paints / thinner to oil based paint. The tinting base has absolutely nothing to do with it. Say you are working outside and throughout the day you have to add a little water to keep the same consistency. If somebody really tried to add 20% to 50% water they no longer would be painting they'd be performing a whitewash or pickle finish.
Repaint — exteriors especially — before visible signs of wear appear, Bancroft says. Don’t wait until you see peeling or flaking paint. “If I have to spend 40 hours preparing the surface before we can paint, that time is going to result in a lot of extra costs. But if I can spend 10 hours preparing the surfaces to be painted, you’re going to save money,” Freeman says.
The cost to paint metal siding -- most commonly aluminum and galvanized steel -- will depend on a variety of factors. In some instances, a simple cleaning will suffice to prepare metal siding for painting. In worst cases, painting professionals will need to repair metal that is rusted, damaged or missing pieces due to climate conditions. In the case of severe damage, a professional will have to remove the old finish and paint to get to the original layer, which will add on to the final price. When you add the actual painting of the metal siding, you might be looking at a final bill between $400 (~250 sq. ft.) and $1,500 (~1,000 sq. ft.).
Also, don't be afraid to ask if the painters are trustworthy people. Unfortunately, there are plenty of cases where a painter has stolen items from a home or caused damage to the house or injury to the homeowner. Subcontractors may not be as skilled as employees, and the contractor you're hiring may not have much experience working with them, making them more of a risk. Additionally, ask if the painters are employees or subcontractors, and what the screening or hiring process is like. If the company conducts background checks, that's a good sign.
Small random-orbit or pad sanders make this job go faster. (Wallis first covers these boundaries with Synkoloid patching compound so no edge is visible after sanding.) As shown, you want to make sure that there is a feathered, smooth transition from exposed wood to old paint. For areas that might get close scrutiny, you can follow up with a 100- or 120-grit rubdown to erase any scratches.
So sad that Angie's List requires the contractor be notified!! They have lost me as a client. If I'm dissatisfied and want to give an "F" rating (question/workers...I SHOULD NOT be intimidated into passing up an opportunity to explain my experience! There is NO WAY my contractor got an Aplus rating from over five hundred people....so someone was lying....yet I can't report that without the contractor knowing it? REALLY?
