I have a question. Should I use different brushes for primer and paint? Or, is it ok to use a same brush? I tried to find the answer on the Internet but couldn't ....
Yes you can use the same brush with different paints as long as you thoroughly clean it and dry it between uses.
Latex paints can be cleaned with soap and water. Oil-based paints require paint thinner, mineral spirits, varsol or turpentine.
How do you clean oil based primer? I tried to wash it with water but it was never washed...– DSKimMay 10, 2015 at 0:25
1Oil based paint requires paint thinner for cleanup - and very likely says so on the side of the can. By now, that brush is presumably ruined. If you prefer soap and water cleanup, buy latex paints (only.)– EcnerwalMay 10, 2015 at 0:57
1You can use paint thinner, mineral spirits, Varsol, or turpentine All will clean the brush– JackMay 10, 2015 at 0:58
You can use the same brush with several types of paint in a short day.
Pro tip from a professional:
Thoroughly wet the brush with water. ( doesn’t need to be hot or warm.) give it a few shakes, tape the medal part on your shoe or tree, wipe it off back and fourth aggressively on your pants or cloth. This prevents the Paint from being pushed so deep into the fibers.
Paint as you wish Wash it right away And repeat.
This DOES NOT dilute the paint whats so ever. Sometimes when I’m painting commercial jobs or any type of paint that ends up drying more quick than I would like it to after an hour or so I will wash it clean and keep going.
Using a brush without wetting it is referred to applying with a dry brush which is not a normal application.
Some people disagree with this as they believe it will increase the chance of leaving a halo mark at the first 4 inches at the top of the wall Due to the fact you will be using a dry roller this does not hold true. If a painter is getting a hail at the cut in line then they are not stippling it with a 4 inch roller. When an artist paints a picture they continue to use the same brush for several colors with no problems what so ever.
Hope this helps !
