Hi sdsester, thanks for the reply.
We're using this paint
which we got from a local hardware store (Home Hardware in Canada to be exact).
I've been finding that you can basically see what you'll end up with not long after putting the paint on. So if I see lap marks 10 minutes after painting they will remain there 4, 8, 24 hours after painting.
The wall we painted is relatively small and it's in the kitchen. We saw the look on the net and really liked it so we thought to take a chance. It'll look great if done properly, but it's just not coming out well because of the lap marks...
Anyway, we've done like 5 coats now. Surely there's a point where it's too much paint? What happens then? What options do we have at this point? Just keep putting the paint on? Try to touch up the lap marks specifically? Any ideas?
