How do I get a smooth finish with latex paint?
It’s impossible to achieve a smooth finish with latex paint without first cleaning and repairing walls and trim. Begin by sponging the walls with an all-purpose cleanser mixed with water. Nail holes, dents or gouges in the drywall or trim should be filled with spackling compound then sanded smooth.

What grit sandpaper should I use between coats of paint?
180 to 220 Grit Sandpaper
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.
What happens if you don’t sand between paint coats?
Why should you sand between coats of paint? Sanding between coats of paint will help you create a smooth finish that is less likely to show brush strokes or other imperfections.

How do you stop roller marks when painting?
To avoid making marks on the ceiling with your roller, reduce the amount of paint you use. If you notice roller marks appearing, re-roll the areas to smooth them out using very light pressure.

Should you rub down between coats of paint?

Can you sand paint to make it smooth?
Sand between coats
It may seem like a lot of work, but it shouldn’t take more than five minutes when the door is flat on the sawhorses. Sand with non-clogging 180- or 220-grit sandpaper or sanding sponges (look for “non-clogging” or “stearated” on the label). Sand just enough to make the surface feel smooth.
How long paint dry between coats?
Adding a Second Coat
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.
What sandpaper should I use on painted walls?
For previously painted water-based paint, sand with a fine-grit sandpaper. For oil-based paint, a medium-grit sandpaper (100- to 150-grit) should be used. Again, wipe away any debris and allow to dry completely.
Should I sand in between primer coats?
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 coats of primer will just extend how long it takes to complete the phase, while sanding at the end of the primer step yields the same results.
Why is my paint brush leaving lines?
If you have the proper paint and tools, one of the key causes of brush marks is the paint dries too fast, before it has time to flatten out. Painting in excessive heat speeds drying and amplifies the possibility of brush marks. Next, the paint must not be too thick.
Why is my latex paint streaking?
This happens when the roller is full of paint and is pressed too firmly against the wall. To fix these paint streaks on walls you’ll need to sand down the raised edges. You may have to touch up the wall here and there but that’s only if you sand too closely. You’ll want to use 120 – 150 grit sandpaper and sand lightly.
Will a second coat of paint cover roller marks?
Roller marks, which painters sometimes call “holidays,” are a routine hazard when painting with a roller, and there are many ways to avoid them. When you notice holidays after the paint has dried, you can usually make them disappear by applying another coat after sanding lightly—if necessary—to remove drips and humps.
Why do my newly painted walls look patchy?
Patchiness usually happens if you don’t use enough paint, or apply it unevenly. Using a touch more paint, and painting in small sections one at a time, usually does the trick. Also, rolling in a grid fashion will get you an even finish too. But, sometimes, changes in the gloss level leave things patchy.
Do you wet a paint roller before painting?
Before you start a paint job, you actually want to wet the paint roller cover with water. “This primes the roller cover to soak up as much paint as possible,” Barr explains. But don’t go too crazy—Barr suggests removing excess moisture with a paper towel and a good shake of the roller so it’s just slightly damp.
How long does it take for latex paint to dry?

Can you wait too long between coats of paint?
Oil-based paint and primer need at least 24 hours between coats. Recoating too soon can lead to poor adhesion, peeling paint, and uneven color.
What grade is wet and dry between coats?
