Gardz thick streaks

[SJRSJR]

So I brush painted a new, dry bare plaster wall with Gardz. I started part way through one tin and as I got to the end I realised it was a thicker consistency. I obviously didn’t stir it properly.

So now I have a wall with some thick steaks of Gardz.

Should I sand it or will it the paint hide it?

I think I’ll stick to mist coats in future.

Thanks

I don't think using a brush was a good idea. Why not use a roller for quick and ease application especially with Gardz as so thin. It's so easy to apply anyone can do it.

Every tin of paint you use you should stir well as the product can separate.
You should of stopped and added water if it was too thick when you realised your mistake.

Stick some 180 grade paper on something flat like a wooden block and sand over. will need another coat of Gardz after sanding

Belated thanks Wayners. I’ve fixed it now.

I originally didn’t use a brush because it was a small area and thought it’d be a faff cleaning up. Lesson learned, it was much easier than paint.

I put it on with a roller second time around and the Johnstones Perfect Matt went on like a dream over it. I’ll give it a second coat but it doesn’t even look like it needs one.

I had decided that I’d do the rest with a mist coat first but now I’m in two minds.

My only question is whether plaster walls should be breathable, which Gardz isn’t.

If the wall is dry then no. It don't need to be breathable paint..
New builds have damp brick and plaster so need 6 months to dry.
If it's just a skim over then a week can be enough this time of year
