SANDING Do not sand after applying tape, remove small lumps behind with your knife before applying 2nd coat. Then sand the rest of the joint lightly in order to make smooth. Be careful not to sand too much off. If too much is sanded off, you will need to apply additional coats of compound.
How much should you sand after spackling?
Spackle can take six to 24 hours to fully dry, depending on the brand and humidity. If it feels hard and no fingerprints show, it is dry. Sand the edges of the spackled area lightly with 120-grit or 150-grit sandpaper, or a sanding sponge.
Sand with fine sandpaper between coats after they dry. Make sure you remove sanding residue before applying additional coats. I recommend three thin coats of paint, but it all depends on the color and consistency. After the final coat of flat paint, sand lightly with super fine sandpaper.
Can you only do 2 coats of drywall mud?
If your wall has distinct crevices, cracks, or textured areas, or if your brand of drywall mud isn’t offering enough coverage, you may have to do a couple of additional coats of compound. However, in general, you’ll need one coat to fill in the seams and three more coats after taping.
At the far end, drywall mud, also known as joint compound, needs to dry for 24 hours between each coat and before sanding, priming, and painting. The 24 hour drying time recommendation can be applied to nearly all factors.
How do you sand a bad spackle job?
A hand held sander is a grip-able applicator that you can set sand paper on for smoothing out surfaces. You will want to use 100-grit sandpaper to level out really rough, high-level spots and use 200-grit sandpaper (which has a more even, gentle distribution of grit) to smooth out the texture.
Do you have to spackle twice?
Spackle Twice, Sand Twice
After the first coat of spackle is applied you have to lightly sand the finish before taking any further steps. Don’t touch the spackled wall until the spackle has dried completely. If you attempt to sand the wall before it dries it will ruin the application of spackle by rubbing it off.
An experienced painter could take care of that problem during the general prep work for the paint job. The spackle spots being painted over complicates the problem, but they can still be sanded out. It will likely take some additional patching after sanding to totally blend the spots in.
How long after spackle Can you paint?

How do you smooth spackle?
Just give it a couple of quick brushes with the sandpaper to smooth it down. If you’re going to spackle over nails or screws that popped through your wall’s paint, use a nailset and hammer to push them in below the wall’s surface.
Lightly sanding (and dusting) between coats ensures you get the best possible result. A pack of ‘tack rags’ is a a worthwhile investment if you’re planning on doing a lot of glossing. To remove traces of dust before painting you can buy special tack-cloths.
Can you wait too long between coats of paint?
After your first coat of paint is dry, it’s safe to recoat typically after four to six hours. A good rule of thumb is to wait at least three hours to recoat your paint or primer if it’s water-based. Waiting 24 hours is best for oil-based paint and primer.
Should I sand between coats of paint on wall?
Primer should also be sanded before the paint goes on the wall; for a top-notch job, sand between paint coats, too.
