Hi, I need help as to the best paint/primer for painted cinder block basement walls. I DO NOT have a sub pump to drain water away from the basement walls. I am not going to install a sub pump. Outside I landscaped the property where all rain water drains away from the foundation. I want to repaint the basement walls and floors so I get the best possible protection to prevent any further mold and mildew. I have basement glass block windows that I can open and a high end dehumidifier in the basement. Paint cost not a problem. There are many products on the market. I will do a good job in any prep work that needs to be done prior to painting. I just want a recommendation what paint products are the best to use on previous painted cinder block. Is a acid wash of floors and walls needed?
Just wash the mildew areas with a TSP Solution in warm water, and scrape off any loose paint, then give the walls 1 heavy coat of Sherwin Williams Interior … use a semi-gloss finish, color of choice… use their highest level product… see my site for help: http://www.paintahouse.com
Will the TPS kill the existing mold? Will a mold killing primer be required prior to using the paint? what about a Mildewcide to be
added to Sherwin Williams paint? Thanks Jim
Yes … and No and nothing to add to paint…… Here’s a note from over 50 years of painting experience: “Mold-killing Primer” like a Pigmented Shellac or an Oil Base Stain Sealer is really not necessary but you can use it if it makes you feel better… Mildew will return no matter what you do… it is a function of the conditions of your dwelling and local climate! At best you can simply “treat it” as it returns perhaps every 5-7 years…
