If you're in doubt about adhesion, do a patch test. IF YOU'RE IN DOUBT ABOUT ADHESION, DO A PATCH TEST. I'm sorry that I had to shout at you, but I did it for your own good. I see so many cases of paint delamination that could have been predicted and avoided had patch samples been applied and then adhesion tests performed.

Numerous paint failures have occurred when smooth faced tilt-up concrete is field painted. Adhesion problems due to a variety of reasons are common. Aesthetic issues include filling voids in the concrete. Since concrete can retain a high level of moisture for an extended period of time, the coating selected must have properties to accommodate this characteristic or alkali burn and saponification may result.

Painting galvanized decks can be a tricky proposition. There are various pre-treatments that can interfere with the adhesion of subsequently applied paint.

The Royal Palms is a three story condominium complex consisting of six individual buildings. Exterior concrete floors had been previously coated with silicone acrylic floor stain.

In Spring, a young man’s fancy may turn to thoughts of love, but a painting contractor’s thoughts turn to booking a season’s worth of exterior repaint work. Like all baseball teams use spring training to review the fundamentals and hone their skills, it’s appropriate that we use this time of the year to review some basic observations and tests you should perform prior to turning in those exterior repaint bids.

I really hate do this again, but I must. I know that some of you are going to say oh no, he’s going to talk about doing adhesion tests again. Yes, afraid so.

Whenever there is a gap between construction materials, it is common to install sealant in the joint.
