To prime your drywall, you need to clean it first by sanding it, vacuuming it, and rubbing it down with a black cloth to ensure that all dust is gone. Once that’s complete, you can begin applying primer to your drywall so that you can ensure that your paint stays in place for a long time.
You’re painting unfinished drywall or plaster.
Two primer coats are recommended in this scenario because much of the first primer coat will be soaked up by the wall; the second coat will replenish any primer absorbed by the surface and hide any flaws in the wall.
Do you always need to prime drywall before painting? It’s important to prime after new drywall installation. The new surface will be porous and will absorb the color of the paint. Primers will also cover the joint compound and provide a good base for texturing or painting over skim-coated drywall.
An often overlooked and important step when renovating with new drywall. After the board is hung, finished and primed, remember to lightly sand the primed walls again before finish painting. Now after the primer is lightly sanded you’re ready for the finish paint. …
If you’re unsure about how many coats of primer you need for the surface you’re painting, a paint store can advise you. Otherwise, start with one coat and check the surface after it dries. If it still looks rough, porous or heavily colored, apply another coat.
Actually, sanding between coats of primer is pointless. Once primer is dry, you should sand the primer before moving on to the basecoat color. … Sanding between layers of clearcoat is also not recommended. Wet sanding and polishing the final layer will yield a better result than doing it between each coat.
For the larger spaces of the wall, apply primer using a 9-inch paint roller with a 3/8- to 1/2-inch high quality roller cover. Fit the moistened roller cover onto your paint roller. Stir and pour the mixed primer into a paint tray. Dip the roller into the primer, making sure it’s completely covered.
It shouldn’t be watery! It’s more of a gel feel to it!
In most cases, latex primers don’t take more than an hour to dry out. However, you should wait three to four hours before applying a layer of paint. On the other hand, an oil-based primer will need a longer time to dry out. You should give it 24 hours to make sure that it’s completely ready for another coat.

Priming the wall seals the joint compound, which has a different texture than the rest of the wall and absorbs more paint than the drywall. Priming blends the joint compound and the drywall, so the surface is uniform. Use a primer designed for painted walls. Apply with a paint roller and use a brush for smaller areas.
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.
You need to lay one layer of mud onto the bare wall to hold the tape, and you can usually lay another immediately after you lay the tape and scrape it. After that coat dries, you topcoat with a third layer, using a wider knife than you used for taping.
While it’s fairly simple to position mesh tape over a dry joint and then apply your first coat of mud on top, mesh tape is thicker than paper tape and can result in more noticeable joints when the wall is painted.
600 to 800 Grit – This sandpaper grit range is perfect for sanding surface imperfections in the primer, prior to paint application. It is recommended to start at the low grit end and work your way up to 800 grit. 1000 to 1200 Grit – When you need to remove base coat imperfections, this grit range will do the job.
It’s tempting to buy 80-grit paper to speed up the sanding job. But because modern lightweight joint compound is so soft, you don’t need heavy-grit paper to sand it. Coarse-grit paper or sanding screens will leave undesirable sanding marks. We recommend 120-grit or 150-grit paper for the best results.
The primer coat doesn’t have to be perfect, but it should cover the surface (no bare spots) and it shouldn’t be so blotchy that you get drips or visible unevenness.
180 to 220 Grit Sandpaper: Finer grit sandpaper is great for removing the scratches left by coarser grits on unfinished wood and for lightly sanding between coats of paint. 320 to 400 Grit Sandpaper: Very fine grit sandpaper is used for light sanding between coats of finish and to sand metal and other hard surfaces.
Primer takes between one and four hours to dry on average. However, the exact drying time depends on the primer type, room temperature, humidity, and the surface you’re painting. Most manufacturers advise waiting at least 60 minutes before painting over the coat of primer.
