Does paint dry darker or lighter? The type of finish you choose also affects the color. If there are lumps, the paint is no longer good. Why do we stir the paint thoroughly before using? To mix the binders and pigments throughly. Separation is common in paint as it sits, stirring blends all the components together so that when you put it on the surface, it all behaves properly. Too much binder will give you thin coverage, and too much pigment can cause the product to fail.

How do you spray paint smoothly? Basic Spray Paint Techniques First, make sure that the surface to be painted is clean, free of rust and debris, and smooth. Any surface bumps or imperfections will show through the paint, so use sandpaper or steel wool to clean and smooth the surface, then use a lint-free cloth to remove any remaining dust.

Can you mix two paints together?

Roll the paint onto the surface with in a large zigzag pattern. Then fill in the space with criss-cross strokes. How do you stir paint with a drill? Drill a hole in the top of the paint can lid. Insert the mixer through the hole.

Hammer the lid on the can. Attach the drill and mix the paint. Sunlight, daylight, fluorescent light, halogen light, and incandescent light affect colors differently. So bring the sample card into the room you intend to paint and look at it several times during the day. See how the color looks using different kinds of artificial light before making a final decision. The only way to be certain about a paint color is to see it on the intended surface, surrounded by the room's other elements.

The best test is to buy sample sizes or quarts of a few colors, paint small sections of a wall, and observe during different lighting conditions. If you're hesitant to paint your walls with samples, pick up some poster board and paint it instead. With this method, you can also see what the color looks like in different parts of your room. Some manufacturers include calculators on their websites to help you figure out how many gallons of paint to buy.

You can also use this formula: Add the widths of the walls, multiply that figure by the room's height, then divide the total by the square footage that 1 gallon typically covers. This formula doesn't factor in doors and windows, so you should have paint left over for touch-ups. Don't forget about a second coat, too! For the best durability and coverage , you'll want to apply a couple coats of paint. However, you might need additional coats, especially if you're trying to cover a dark color with a lighter color.

In this case, you'd want to use a primer as well. The accrued costs of frequent repainting cancel the savings you enjoy by buying the cheap stuff. Good-quality paints cost more because they have a higher percentage of titanium dioxide, which determines covering ability, and other additives that increase durability. The heavier bodies of high-end paints help them go on smoother, splatter less, and resist fading. You might be tempted to buy a cheap, throw-away fuzzy-napped roller, but save yourself the headache!

You can load three or four times the amount of paint onto the roller. This porosity means less dipping into the roller tray, which means more coverage in less time.

For smaller jobs, consider a paint pad. It splatters and drips less than a brush. Most pads even come with a plastic paint tray and airtight snap-on lid. For best results, choose brushes with long and dense bristles. Use nylon for latex water-base paint and natural for oil-base paint. Follow these brush tips for most painting projects:. Look for a bare wood handle to get the best grip. Hold it between your thumb and fingers in a relaxed grip.

High-quality brushes apply paint in a thick, smooth film. Examine a brush for a good taper, with bristles in the center slightly longer than those at the edge. The bristles should be at least half as long as they are wide and should be bound with a rust-resistant metal ferrule that is nailed on, not just crimped to the handle.

Look for a well-shaped, bare wood handle large enough to grip comfortably. Specialty painters tape is used to mask off areas before painting. Medium-adhesion tape is often used on woodwork that has a nonporous finish, such as gloss or semigloss paint. It adheres and seals well and will stay put for the duration of the project. If left on too long, however, it may pull off the finish when removed. Low-tack painters tape for delicate surfaces is used to temporarily mask off stripes, borders, and wall panels.

It is often removed immediately after painting. Its mild adhesive will not pull off paint when removed. Both types of tape are available in a variety of widths. Paint will cover more uniformly and adhere better to clean, dry, nonglossy surfaces. Scrape off any flaking paint, fill holes with spackling compound, and sand walls. Wipe off sanding dust, and wash dirty walls with a trisodium phosphate TSP solution.

Remove switchplates and other hardware, and apply a primer, which helps to conceal stains and ensure uniform color and absorption. Apply no more than inches of painters tape at a time to be certain of a straight edge. Smooth the edges with a putty knife and heat-seal the tape to prevent paint from seeping through.

Run a tapered painter's tool quickly over the applied edge of the blue masking tape after you've set the tape. This heats the edge of the tape, the waxy adhesive on the tape melts, and when it resolidifies at the edge, it creates a barrier that prevents paint from seeping underneath the tape. Wait until paint is dry to the touch and remove the tape slowly at a degree angle. If the tape begins to tear, run a crafts knife along the seam to loosen it from the dried paint.

Instead of spending hours masking off the glass, rub lip balm around the inside of each pane. When the paint dries, take a knife and score around the glass, then scrape the paint and wax away. If you still have wax on the glass, heat the glass with a hair dryer and buff clean. Always paint from a small plastic bucket, not the paint can. That way, you can keep the lid on the can so the paint stays fresh. Pour only a couple inches of paint in the bucket to create less weight to carry and help you avoid overfilling the brush.

Use a 5-in-1 tool , not a straight screwdriver, to pry up the can lid around its circumference.
