Give your piece a full sand with a very high grit sandpaper!
A butter smooth sanding all over with change your piece dramatically. Use 400 grit (or higher) piece of sandpaper all over your piece and I PROMISE you that you WILL feel a difference. I use this one, but any soft sandpaper with a high grit will work.
Sand down the bad areas until you can feel a smooth and flatter surface, wipe clean with a terry cloth, and repaint with a 3/8'' NAP paint roller. You'll want enough paint in the roller that it's ``loaded'' but won't cause the paint to drip.
Generally for every 1 cup of paint I recommend adding 1 -- 2 tbsp of water. This will help the paint lay down smoothly and minimize brush strokes when painting furniture. The water essentially acts as an extender to improve the self-leveling characteristics of the paint.
Use a piece of large general use sandpaper and gently rub a specific area in a circular motion. Do this over all irregularities until the surface feels smooth under hand. Simply wipe away any sand and dust debris before painting another layer.
Old paint might have debris or clumps (even if it's an unopened can!) and new paint might need to be stirred.
Your paint may be too thick. Whether you are spraying, brushing or rolling, the consistency of your paint is essential. When spraying, I always add 1-2 ounces of water for every 10 ounces or so of paint. When brushing, I use a mister to spray a light mist of water onto the surface when doing my final long strokes.
In short, that rough texture that you feel is basically a mix of micro-level dirt that has stuck to your clear coat that won't come off with a simple wash. It can be things like industrial fallout, paint overspray, metal shavings, dust, etc…
SAND IN BETWEEN COATS
Sanding in between paint coats will smooth out any imperfections like dirt or loose fluff that may have stuck to the paint as it dried. It will also even out any brushstrokes/roller marks. But not with any sandpaper...you want a superfine sanding pad.
Using sandpaper, you canremove the lumps and the excess paint . This will help smooth out the paint, and adding another layer will improve its look. You won't damagethe canvas , and you'll be able to get rid of any excesspaint that might affect the look of your artistic creation.
Why it happens: Uneven or blotchy paint occurs when you've either skipped priming or not adequately primed your wall before painting. This can also result from not applying enough coats of paint to get a uniform finish.
If you want your paint to have a smooth finish, the technique you use is very important. Keep your brush at a 90-degree angle while applying the paint and feather as you go. Between coats, sand the wall lightly using a very high grit sand sponge of at least 220 grit.
Use this Flood Floetrol 1 qt. Clear Latex Paint Additive to improve the performance of latex and acrylic paints and reduce the appearance of brush marks. It allows latex paints to be sprayed with less pressure to help reduce tip clogging and piston freeze-ups.
By painting with a very light touch, you can create a smooth, flat finish with ease. If you're finding the paint a little thick, dilute it with water to help it go on even more smoothly. You can also sand lightly when done, too. After painting, seal indoor furniture with Chalk Paint® Wax.
Using a paintbrush, start at the center of the touch-up and slowly move outward. Lightly extend the tip of the brush just beyond the area you're touching up to seamlessly blend the touched up area with the original painted area.
Use light and steady pressure when wet-sanding. Keep the surface wet by spraying water on it if it begins to dry out. Repeat the sanding process using the same sanding technique but with ultra-fine 2,000-grit sandpaper. This removes the grit lines and makes the paint smoother.
if you've painted something and you end up with trips, you can fix it. just get some high grit sandpaper, 500 or more, get it wet, and then start sanding. sand until you feel like the drip is gone. and then let it dry.
It is easy to smooth out touch-up paint with lacquer thinner. Simply wipe and dry the area, dab a small amount of the solvent onto a cotton swab, and massage the paint glob away slowly.
Applying the second coat too early will result in lost time, money, and effort. Not only that but it'll also create additional stress that's not necessary. Applying the second coat too early will result in streaks, peeling paint, and uneven color.
