Why does my paint lose coverage upon drying?

Question

I am using Taubmans Duraclean in cream and am finding that I need to use an undercoat and 2-3 coats of paint to cover a very light blue/grey wall. The paint goes on fine and gives coverage then seems to lose its volume upon drying, exposing the previous colour. I have never had this kind of poor coverage before...is it me or the paint.

Answer 1

blue is one of the worst colours to cover. It 'bleeds through' as you have found. Just keep up the recoats or maybe switch to Dulux that always seems to have good coverage (personal favourite).

Answer 2

I used to sell lots of paint and accessories. I found that most coverage problems were caused by 1.) the use of a poor quality roller pad or 2.) trying to stretch the coverage of the paint.
1.) a poor quality roller pad has very little fabric on it...when it gets loaded with paint, a very uneven coat of paint is applied, which results in poor hiding. 2.) If you do use a good roller cover..(shud cost $3.00 or more) make sure that you load up the cover with plenty of paint...take the loaded roller to the wall and apply the paint to the wall in the shape of a "w"...then spread the paint over an area no bigger than a sheet of newspaper ( maybe 3-4 feet wide x 3' high). Then go back and get another load of paint aqnd do the next section of wall.
This shud help do the trick. The idea is to lay a nice even coat of paint on the wall...Also, make sure you use a roller cover that is suitable for latex paint....I would also recommend that you use a 3/8 or 1/2" roller pad, especially if the wall is textured. I hope this helps you.

Answer 3

Could be either or both. If you spread the paint too thin, the original color will bleed through when dry. May not be enough pigment in the paint also. I always use a primer/sealer first when changing colors. This not only helps prevent bleed through, but assures the true color of the new paint.
