Hi, i had to take down ceramic tile in my bathroom behind the vanity. It was glued up with mastic or some sort of adhesive. Well i had a real mess behind that sink and have some deep gauges. I managed to sand down the entire surface using my electric sander. Now i am ready to spackle the area, only thing is i really suck at this.
Can any of the pros give me some pointers at spackling?
Didn't know if this should be in the painting section or not?
I'd rather put on ten layers of thin spackle than have to sand it down once, I hate that dust.
Now I use a wet towel over a 2x4 and quickly wipe the surface smooth. If the spackle starts to soften and pull away, I'll let it sit for an hour and then start over.
For big fill areas, I pack it in thick, and give it a few days to shrink and crack. For the finishing, add a little water to the mixture and stir until it flows nicely. Use a 10" spreader, and only 2-3 strokes only at 45deg to each other. Let dry and repeat.
If the drywall is really messed up it might be easier to cut out a section (say 3' by 5') and replace with wonderboard or hardibacker. That way you've only got the four seams to tape and mud, it will be easier to work with, and it will be more water resistant than normal drywall. Not sure if this helps but it might be easier in the long run. Best of luck.
