Hi all,

This is my first post here so hi to you all. DIY is not my strong point by any means but I'm usually reasonably good at it, but painting my on the inside of my front door has gone wrong - very wrong. The door, inside my flat was originally brilliant white gloss paint. I've sanded the gloss paint down so that there was no shine and it no long had any smoothness to it then used 2 coats of primer leaving each coat 2 hours between each coat and sanding lightly each time. After around 5 hours after 2nd coat of primer wad painted and dried I painted the top coat but it really didn't work out.

I can still see the primer underneath and even though I was cutting with a handheld brush I still got the same results. The topcoat was applied using a roller and it looks just awful. Would I be best to wait for it to dry, then sand down until the gloss has been removed and start the primer again ? Unless, when the 2nd coat is applied all might be well - but I doubt it, so I've included a photo to show you what it looks like.

Hope someone can help.

Thanks

The blue is such a strong colour that really, you need to apply a dark grey undercoat or it will take several coats of gloss to cover the white. Now you've got to this stage, if it was mine, I'd just lightly sand it to provide a 'key' then apply a coat of dark grey undercoat, which will cover it well, then two coats of the blue gloss. That's what I did when I painted my front door dark blue, which turned out fine.

(You need to make sure that all the paint are compatible. For example, if the blue is water based then use water based undercoat, or if oil based, use oil based undercoat. You'd only need a small tin - 500ml or 750ml).

I hope that might help.

Good luck with it.

David.
