Abrasives for plaster walls
« on: September 15, 2012, 01:13 PM »
Just need some advice on what is the best 150 size abrasive to use on plastered Walls. I have the ets 3 sander and have got to sand down a load of old Walls after I ve filled them . Been on the festool website but there's no definitive answer on the right abrasive. I'm thinking maybe saphir or crystal? Cheers.

Most certainly none of the above. Crystal and Saphir are way too sharp to get a good result. They are meant for the toughest of jobs. Plaster, on the other hand, is a very soft material. You want a more gentle abrasive to handle that.

I have found Granat works best on plaster walls, mainly because it doesn't clog as fast as other types of abrasives. I never go lower than grit 80 on the roughest of patches, but mostly use 120. If you can't get Granat, Brilliant also does fine but it will clog quite a bit faster so you'll use up more sheets.

Nice one for that Alex. Have never sanded Walls before so that advice is much appreciated

Agree with Alex, Brillant 2 was my go-to abrasive for plaster repairs until Granat came along.
Not as many Sanders as PA Floor guy.....
