Oil based primers are best for exterior siding

Great adhesion over old paint. Dries quick. Oil based primers work best for exterior siding

Better than Water Based

Would Recommend

This oil primer is better than any water based primers if you want a strong seal and solid coverage. However, it does take a while to dry after coating. In 85 degree weather today, it was still tacky after 2 hours. It will also smell strong for about a week, and die out within two weeks. But I would still buy it when I need higher quality than water based pain.

Does the stain locking, but not good for priming

I bought this primary just for the stain blocker due to rust leaching that was occurring on the walls in my bathroom.

One my project I was painting my bathroom which was a horrible mint green-g...

A Toxic Nightmare That Makes Homes Unlivable

Would Not Recommend

This primer is a toxic nightmare. As an experienced applicator who has used oil-based coatings since the early 1980s, I am not squeamish about standard oil-based paint fumes, but the VOC levels from this product are completely indefensible. Whatever properties it is supposed to impart, I cannot imagine they justify making a home effectively uninhabitable. No amount of ventilation will save you. Aggressive mitigation measures were put in place before application. We completely sealed all air ret...

Stinks to high heaven

I bought this to cover wallpaper so I could paint over that. It did not have the coverage that was advertised, and the smell has lingered for over a week
