Do Manufacturers Overestimate their Paint Coverage?


Postby Zacccc » Thu Jul 02, 2015 4:17 pm

I had a small back bedroom completely reskimmed about 6 weeks ago. I've just put a mist coat on using No Nonsense Trade Contract Matt (Brilliant W). I didn't thin it because the tub said it wasn't necessary for a mist coat. The tub says it covers 10-12 sq m. per litre. I've measured my back bedroom carefully and all walls and ceiling comes to about 27 sq m., certainly no more than 30 but I've used at least 8 litres of a 10 litre tub. I put it on fairly liberally but not too much I wouldn't have thought. Do the manufacturers generally grossly overestimate the coverage of their products?

I'm now intending to put a single coat on of Dulux Trad Vinyl Matt (Pure Brill W). I've read somewhere that you can get problems using different makes of paint/emulsion but I also read that you can use any make of cheap emulsion for a mist coat so I'm not anticipating any problems. Already with the mist coat the bedroom looks great apart from one or two places where the ceiling meets the wall and the paint has cracked, I think perhaps because I've put it on too thick. But would these disappear with a coat (or maybe two at those points) of vinyl matt?


Thanks for any advice or comments.

Unfortunately I have always the same problem. I do not remember the makes of the paints I used but one laye ralways seems not enough to cover the previous colour. Or in the light you can see some shades... I always paint twice...

Exactly. We should not believe the manufacturers in everything. And is why I like this forum, you can check here many things :)
