Sand and cement on plasterboard
Hi paul hope you well recieved your dvd and very pleased,will tackle skimming spare room soon! Quick question does sand and cement stick to plasterboard?
Sand & Cement will not stick to plasterboard - however if the plasterboard is properly prepared it will do.
This may not be officially guaranteed but this is what I have done in the past:
Apply a 50:50 solution of PVA to plasterboard
Mix some sand in with neat PVA to form a slurry mix and roller this onto the plasterboard.
This dries to form a very rough surface to which sand & cement will stick to.
However it should be noted that plasterboard is designed to have the finish coat applied directly to it. If it needs levelling then boding coat will stick to plasterboard no problem.
But if it is to practice or for any other reason then one or two coats of the slurry mix will help you apply sand & cement.
Let me know how you get on!
