Hi
Got a house internally insulated with insulated sheets with plasterboard. The boards were secured with mushroom pins ( min 12 per 8th x 4th board). There was a poor quality job done skimming the boards ( skim coat not thick enough) with the result that mushroom pin heads are now visible through the paint. The Walls look ugly and is a source of constant comment from visitors.

I'd like to know if there are any solutions for this issue apart from re skimming the Walls. Any advice or ideas greatly appreciated

Thanks
 
You need to describe the problem in more detail. When you say showing through- is it a "3d" or "2d" show through.

If 2d, a few extra costs of paint should be sufficient. If 3d, you might need to fill and sand- assuming the problem isn't too big.
 
It's a 2D problem. There is only a minimal amount of skim covering the mushroom pin heads.jha n. I've tried to cover with multiple coats of paint without success. I got special paint at the weekend for covering stains and will try that next

You may need a primer- there are different types. Solvent based primer might be required.
 
Is the wall smooth to the touch?
Did the plasterer drag the skim too much and you can see the edges of the pegs?
If it is not then you will always see the pegs due to your bad skim job.

If it is smooth, primer paint as suggested.
