Flaking Paint

Emma133

Hi I recently decorated the lounge in our house and the paint on the skirts is flaking off in quite a few areas. It is quite an old house and the paint that was there in the first place was all stripped off as it was so thick and clumpy, I am unsure where I have gone wrong?

Any advice? I am about to start the hallway/stairs are and do not want to make the same mistakes.

Thanks

Can you tell us what you did after you stripped the old paint off?

You didnt just put gloss on bare wood? :eek:

hi thanks for the quick reply, I gave them a quick sand and put two coats of primer on then coated with satin wood top coat and now I have lovely big blisters showing dark brown wood all over

Probably resin from knots in the wood - you may need to sand down again and try a couple of coats of aluminium-pigented primer.

Or use good old-fashioned shellac-based knotting solution.

That has thrown me lol, as I have never encountered this before, and yet I paint new wood all the time.:(

When I prime, I always undercoat as well, then I apply the top coat, either satinwood or gloss.

Its definately a puzzle

Just a thought.... You havent mixed a water based product with an oil based one?, ie, applied the primer using oilbase, or waterbase, then did the satinwood in oil or waterbased, as the two wont go together.

I made that mistake, waterbased and oil based satinwood - I didn't even realise they could both exist, still rubbing it down:o

lol, you wont make that mistake again :eek:

Thanks for the reply just to clarify its not new wood its old old skirting that has probably been on as long as the house has been here! When stripped bare the wood is nearly black as if it has been coated/dipped in something.

I am quite certain that both the primer and top coat were waterproof but will be extra careful on the next project and make sure I double check.

If you've stripped it right back then you have probably removed the original knotting that was used. The resin can bleed through for years if not sealed. Primer will not do it, as the resin is oily.
