Applying primer first is the best way to ensure a perfect finish later. Just as it does with makeup and on cars, primer creates a smooth base that promotes better adhesion and truer color from your topcoat paint. Pro-tip: Apply primer using a brush first to “cut in" around edges, then use a roller to fill in.
Rolling on primer or paint is best for flat panels, the finish will be much smoother. The tight corners should be brushed first.
Use your fingertips to dab the primer onto your forehead, nose, cheeks, and chin. Smooth it out: Gently massage the primer into your skin using circular motions, starting from the center of your face and working your way outwards. Be sure to blend it evenly towards your hairline and jawline for a seamless finish.
A flat foundation brush applies primer nicely.
No. But I would use a thicker roller (at least 1/2'') and push it some so you get the grooves. It will save a lot of time and be more even finish. Also your primer coat looks generally splotchy. It takes practice to roll things uniformly, but the trick is to use plenty of paint. Do not dry roll.
Most latex primers dry to the touch in 30 minutes to one hour. But for best results, don't paint until the primer completely dries—which can take up to 3 hours, depending on temperature and humidity. Once the primer is completely dry, it's prime time for painting.
Many painters “break in” a roller cover by priming it with water or thinner. In our lab we never prewet a cover before painting. If you choose to, you must spin it out with five or six strong pumps so it is only lightly damp. Then take even more moisture out by blotting the cover with a paper towel.
You probably don't need a primer. If the current wall is smooth, clean and covered with the same type of paint (both are oil-based for example), you can head straight for the paint. You need to fill holes, spackle and sand*, maybe even cut a new piece of drywall in to the existing wall.
PCR primers should have a length between 18 and 24 nucleotides, and probes between 15 to 30 nucleotides. The optimal melting temperature (Tm) of a primer is 54°C or higher. The annealing temperature (Ta) of a primer is often above its Tm (of 2-5°C).
You will want to use 2-3 coats of primer to ensure there is a good bond between the new paint and the wall, and also to cover up any previous colors, especially if they are red, orange, or a strange outdated color. In short, you will typically need 2 coats of primer for most painting projects.
Let the primer set for at least 30 seconds before applying makeup. Apply your Color Correctors and/or Favorite Foundation to your skin and see how much smoother your complexion looks after using a primer first.
Professional painters typically use both brushes and rollers when painting. Brushes are used to apply paint in tight spaces or areas with intricate details, while rollers are used for larger surfaces like walls and ceilings.
You don't need any brushes, sponges, or other beauty tools to apply primer—your own two hands will do the trick.
Primer doesn't need to look perfect but try your best to apply even coats of primer on a surface for best results. Should I sand between coats of primer? It's not necessary to sand between coats of primer. You can lightly sand your last coat of primer for a smooth surface before applying color.
Most projects where you're going over a previously-painted surface do not require the use of a primer. In many cases all you'll need to do is spot-prime any bare areas that need to be addressed before applying your finish.
If you have various stains, shellac Bonding primer is the ideal choice. It can be used to cover rough surfaces and old varnish as well as metal and ceramic.
After the primer dries, lightly sand away bumps and ridges using very fine grit sandpaper folded into quarters. When the grit of one section of sandpaper becomes covered with dust, switch to an unused section and continue. Wipe the wall clean with a damp towel or sponge and allow it to dry before painting.

Adhesion – A slightly roughened surface provides better adhesion for the paint. Smooth sanding creates microscopic grooves in the primer, which help the paint to bond more effectively to the surface.
Not Fully Loading the Roller
The roller needs to be fully loaded with paint to the core, otherwise you'll get air bubbles on your wall, resulting in “paint acne.” To avoid this mistake, roll back and forth on the roller tray until all bubbles are gone and the roller feels heavy.
Lint from new paint rollers can find its way onto your walls, which is decidedly not ideal. Instead, roll the new cover over some painter's tape and preemptively remove some of that fuzz. If you do end up with paint fuzz on your interior walls, you'll need to use high grit sandpaper to remove it.
Paints and primers with glossier sheens, like enamels, are most compatible with woven roller covers that shed less lint and deliver smoother finishes. Oil- or water-based paints are best applied using knit roller covers, since they have a more “open” fabric construction to pick up and release greater amounts of paint.
