Hi, hoping someone can help with this....
We're renovating a house, and, because of time constraints I thought I'd make a start putting a mistcoat on the new plaster over Christmas and New Year. I opted for Dulux Supermatt, because the plaster wasn't fully dry in all areas, and I was under the impression supermatt would still allow it to breathe and continue to dry out. I only painted those areas that looked pretty dry, and avoided any that obviously weren't.
However, I'd failed to take into account that the house was really cold, with no heating, and in the middle of the festive cold snap! I can only assume the paint might have frozen, because there are areas which I am able to rub from the wall. These areas, I guess, might also have been wetter than other areas. I have to rub quite hard, with a cloth, but the paint does come off. It seems fairly obvious that these areas need to be rubbed off and redone. That didn't seem too bad, and didn't take me too long.
BUT, then I noticed that even the areas of paint that seemed to have dried perfectly, will come off if I rub hard enough. Out or curiousity, I've run the edge of a scraper (with reasonable force) down an area of paint, and it will blister, then allowing me to scrape bits of it off.
I'm worried that the paint never set properly, and if I leave it, it will peel off eventually anyway. This is obviously going to be a nightmare of a job to get all the paint off, but I'm wondering if it's necessary? Basically, can anyone tell me whether it's a bad sign that I'm able to scrape off a mist coat of Dulux Supermatt? Or am I just being stupid, and of course a mist coat isn't strong enough to stand up to a scraper?!
Interestingly, I did one wall with a bog standard watered-down emulsion before I turned to the Supermatt, and that doesn't allow me to scrape any off - it seems to have soaked into the wall much better than the Supermatt.
Anyway, enough waffle....any thoughts? Thanks.
