I was having artex peeling problems in this thread:
//www.diynot.com/forums/viewtopic.php?p=1455012#1455012
I'm now on to the issue not of peeling, but of making a topcoat actually show up as white ... and this seemed like a different topic that may affect a lot of people painting ceilings that have either artex or fresh plaster, so I've posted it here as a new topic.
I painted my newly artexed ceiling using B&Q Colours Pure Brilliant White Matt Emulsion. After several coats, the ceiling still looks off-white, with the artex colour showing through somewhat. I take this to mean that the covering power of the B&Q paint is poor, OR that the artex is too thirsty for any paint and requires sealing first.
I'm changing paint in the hope of getting better whiteness (opacity).
I've now bought Dulux Trade Supermatt thinking it is ideal for new artex as I read that you shouldn't cover new artex in a matt containing vinyl. But, I'm a bit worried about using the Supermatt now because it is just White (everything else is Pure Brilliant White). So my questions are these:
1. If I seal the whole ceiling in Uncercoat or BIN, can I use a vinyl matt without any problems?
2. In fact, for future reference when painting over artex or plaster, instead of mistcoating and being restricted on paint to non-vinyls, isn't it better just to seal the whole ceiling with Undercoat/BIN and then use any paint you like on top (including vinyl) because the sealing prevents the thirstiness of the artex from causing problems?
If the seal+choose any paint you like option is best, I think I'll go for Dulux Trade Vinyl Matt or Flat Matt or something else that is available in Pure Brilliant White instead of just white, and also that forms a neater film rather than what I've read re Supermatt as being a chalky finish that will come off with a wet sponge(true?).
Cheers.
