When to Use a Paint Additive
This liquid ingredient allows paint to be thinned without altering its opacity or viscosity. Here are three ways it comes in handy
- If a sash or door needs two coats to hide a dark color, paint straight from the can may cause a buildup that will chip or make it harder to operate. Two additive-thinned coats can avoid those issues.
- When paint is drying too fast as it’s applied, an additive will extend working time, so that brushstrokes blend better and paint dries to a smoother, more uniform film.
- Treating a brush’s bristles with an additive helps to keep paint from drying on them.
