Painting over painted exterior brick
 
What is the best method to paint over exterior brick paint. My exterior brick has been painted and it needs repainting. Do I just power wash and paint away? Is there specific paint that should be used.:mad:

If the existing paint is still holding ok, you should be able to power wash and repaint. Chances are the power washing is going to knock a few spots off, so be prepared to spot prime a little. If the old paint is chalking, it is best to reprime before painting or the new paint will not adhere very well. Best advice is to go to a real paint store, like Benjamin Moore or Sherwin Williams, and follow their advice. Stay away from Home Depot and Lowes paint dept.

I agree, stay away from home depot and lowes. There employees are not properly trained. I am a professional painting contractor in NY. Power wash the surface, clean with tsp, scrape any loose paint, let surface dry, prime with a masonry primer that's 100% acrylic, and apply two top coats of a paint that's 100% acrylic. I would prime with a100 from sherwin williams and top coat with super paint from sherwin williams,we use both products on a regular basis and have never had a problem, they can also both be used on masonry and we do use them on masonry.

Liquid concentrated tsp. The liquid concentrated tsp is mixed with Water in a pump sprayer and sprayed onto the substrate and rinsed off with a pressure washer

Welcome, we use it often in that form. Its in a 16oz bottle and that one bottle will make a couple of gallons after its mixed with water, then we spray it on, brush it if needed, then power wash it off.

If you have a low GPM home depot type of pw you probably will not get allo the TSP off and it will etch your windows. Beware...
