Eggshell Type Cracks in Plaster Skim on Plasterboard


Postby the_lar » Mon Aug 08, 2016 8:11 am

Hi all,

I'm embarking on a plastering job at home, my hall stairs and landing basically. I'm practicing skimming some plasterboard sheets at the moment in my garage and did my first 1800 x 1800 trial yesterday.

I thought I'd got a really good finish and was very happy with it, however when I came to check the finish this morning, the skim has cracked like an eggshell pattern all around the edges. Now I'm fairly sure this will be because it dried out too quickly(???) - it was very hot yesterday afternoon when I was doing it. Is that the most likely cause? Or could it be that I didn't put the plaster on thickly enough?

I didn't do anything to prepare the plasterboard sheets first, I just slapped the Thistle multifinish straight on, but should I have 'sprayed' the sheets with water first or used PVA?? Sorry for basic q's, I'm just a bit confused as to what I've done wrong.

Many thanks
Kevin

your correct, it has dried to quickly, you can pick it off, paint a pva solution on the areas and mix a bit of plaster and go over it again
