Another type of paint is on the market that claims to be a primer and paint in one. Basically, it’s just thicker paint and costs twice as much as regular paint. Most professional painters aren’t fans, but if you have exterior walls in excellent condition already, and the self-priming paint is the same color as the original paint color, it could certainly save painting time with one coat going on instead of two.
Prep work should include removing all loose paint, either with a pressure washer or by scraping; removing any trace of mildew using bleach and water or a commercial solution, and sealing or covering dark stains; caulking all seams, corners and around windows or trim; applying epoxy filler to repair serious woodwork problems; covering dark stains; sanding all rough surfaces, and priming the bare wood with a bonding primer.

I can't say enough great things about Saints of Paint. They went above and beyond my expectations in every possible way. They painted the entire interior of my house and the work that they did was perfect, thorough, and very reasonably priced. Not one detail was missed. On top of that, each member of the team is very friendly, honest, and considerate. Broomfield House Painting
Interior and exterior paints need to stand up to entirely different menaces. Paint on the interior of your home will need to be cleaned or even scrubbed, while exterior paints need to be weather and sun-damage resistant. Both exterior and interior paints are a combination of pigment, solvent, resins, and additives. The solvent in paint keeps it liquid and spreadable until it dries on your wall or trim. Latex paint dries more quickly because its solvent is water, while the solvent in oil-based paints is mineral spirits, which takes more time to evaporate. Once the paint is applied, the solvent evaporates, and the resin allows the paint to adhere to the surface. Various additives in paint give it desirable characteristics, like moisture and scrub resistance.
Your contractor will sweep or scrub the concrete first with a dry brush, and then clean it thoroughly with trisodium phosphate (TSP) and warm water, then let it dry. TSP is a mostly alkaline solution that does a great job cleaning grease and oil off concrete surfaces. Brush painting concrete siding costs $138 per 100 sq. ft., roll painting costs $50 per 100 sq. ft., and spray painting $32 per 100 sq. ft. Home Painters Broomfield CO
