Tint Your Plaster For Touch Ups on Primed Walls & Trim
If you are patching or filling holes, scratches or dents on primed white walls or trim it is a good idea to mix a little colour (paint tint) into the filler you are using. If you don’t, it is very easy to miss some of these spots when you are sanding and spot priming afterward.
Why is this important? Any areas that you have filled must be spot primed before you apply a finish coat of paint, if you do not prime these spots, they will show up as flat, dull spots on your finished walls and trim (even on low sheen finishes like eggshell). by adding colour to your filler you will be able to see all the spots you filled, sand them and spot prime them all – this applies to mouldings and any built-in woodwork as well.
Most lumber yards carry small tubes of paint tint that you can use. You won’t need much so just get a small tube. You can also buy coloured fillers at some stores but is much more expensive. If you are in a bind and cannot get the paint store, a very small amount of a deep coloured latex paint will work – paint tint is better though.
