This item was easy to apply, especially since the last time I painted it was finger paints by number set when I was 7. So far, no further mold has shown through. Maybe I should resume my finger painting and I was better at it than I knew. I would definitely recipe d this product. Now if only the company made something that actually worked for the weeds that grow on my lawn that I can never get rid of!

PRIMER IS BETTER THAN GOOD

This primer is amazing. I had all fences paired with end posts and all of them held a white color but the last I bought and prepared did not hold the white color. I was thinking they may have been untreated wood and kept leaking a brownish color onto the white and because an annoyance to look at. I thought a good primer that could be strong enough to prevent the wood from leakiing out to a different color was in need but which one? I read how people came back after blocking and killing mold and didn't come back and this is what I came up with. I love the texture and it covers well and covers completely. I love the color it was a bright white and never left a doubt that it may have done more to the board to not allow anything that could effect the result. It actually was so brilliant in shade that it in a way made the other posts look shabby. It was a bit pricey but if it could cover for good what more can I ask for? It has been 2 days, it covered well and dried quickly and it rained last night and had about 7 hours to cure and was beautiful this morning. i am still very pleased and will look into this type again because I do deal with mold issues and have trouble finding powerspray services. This at least reduces mold on painted products and is true! Thank you for a solution that I would look into again for the future. It has saved me so much!

I'm really happy with this primer. I used it on an area with mold, and it covered everything extremely well. The application was smooth, the coverage was even, and it immediately made the surface look clean and sealed. It dries quickly and feels like a solid base for repainting. If you need something that actually handles mold and hides the staining, this worked great for me!!
