Once you’ve revived dried or poorly stored paint it is critical to verify its sticking power to ensure it will bond properly to the surface you are applying it to. Poor adhesion can lead to chipping and separation after drying, which ruins the appearance and longevity.

Begin the evaluation, start by applying a minor test area of the rehydrated paint to a pristine, prepared panel representative of your final project. Use a scrap piece of wood, metal, or drywall that has been treated with the identical base layer you intend to use. Allow the paint to dry completely according to the product guidelines.

When fully hardened, employ a precision knife or razor to cut a grid pattern into the paint film. Form a grid of 12–18 tiny sections in a pattern with 6–7 mm between cuts. Ensure incisions penetrate the film and reach the underlying material without scratching the substrate.

Follow up with high-tack adhesive tape over the grid and rub it down thoroughly using your thumb or a squeegee. Then quickly pull the tape off at a 90-degree angle.

If the paint comes off with the tape or if large pieces of the grid are lifted, then the adhesion is poor and the rehydrated paint is not suitable for use. When the paint holds its shape and only a few small flakes are removed from the edges of the grid, https://www.nmosktoday.ru/news/business/98196/ the performance meets standards.

To double-check results, run the test on another substrate or after a longer cure time. Always note that restored paint rarely matches new paint quality, so even if the grid survives it may fail prematurely in extreme weather.

Should the test fail, opt for new, unopened paint or modify the thinning procedure by incorporating a compatible additive designed for the paint type.

Conducting this evaluation ahead of time saves time, money, and frustration later on.
