Newbie question - dulux trade stain blocker

Post by Meh_of_House_RoF »

I’ve put two coats on as has been recommended on valspar painted walls. I’ve done one coat of matt emulsion and I can see a thick white outline from where I cut the stain blocker in. I was planning to do two coats but I really don’t think this will cut it, it just doesn’t want to adhere.

So my question is... was I supposed to use a base coat on top of the stain blocker? Would really appreciate some advice before I throw more expensive paint after bad [emoji85]

Thank you in advance

Dulux Trade Stainblock does work well but draws any staining into it, leading you to think it may have failed. I'm sure it's a 6-hour re-coat period for this product and it's important it has properly dried before any emulsion is applied.

Is it Valspar Trade emulsion you've used, as the retail equivalent of any trade brand, can have quite awful opacity.

I have recently done one of the Valspar smelly paint cover up jobs procedure as follows
I flattened all walls (deros)
applied first coat Dulux stainblock to all walls, then left overnight (B & Q said 45 min recoat time) Dulux say min 4-6 hours
then applied second coat Dulux stainblock to all walls,
This was then left for one week
Two coats of Johnstones coverplus mixed to a Little Greene colour was used,
this was done approx six weeks ago, and at present everything seems to be ok.
The spec above was from Valspar so I followed it to the letter so if the problem comes back it is there problem again not mine.

Thank you, that’s helpful to know it should theoretically work....

Originally had valspar. Applied one coat of primer, second coat around 10 hours later. Left to cure for about 4 weeks [emoji85]

Top coat is farrow and ball. I’ll persevere with more coats and hope for the best.

How is this the first I’m hearing of it? Just read Valspar paint smells similar to cat p*ss after a couple of weeks?

That’s bloody terrible.

I've used the Valspar v700 emulsion on a number of jobs over the last few years, including last week, and had no trouble with smelly paint.

Three coats have done the trick! Thank you guys!! People were saying I should put undercoat on and then repaint so you’ve definitely saved me some time [emoji322][emoji322][emoji322]
