What Happens If You Paint Without Primer

Primers are not e'er necessary in every painting projection. To know when you should use a primer yous outset accept to empathize what types of primers are available and what they're intended to be used for. The all-time way to understand their intended uses is to get-go look at them past primer categories.

Drywall Primer

New/bare drywall is extremely porous and soaks up pigment like a sponge and causes it to embrace better in some areas than others; especially when you're comparing drywall mud joints to the surrounding areas. Porous surfaces like drywall mud will crusade visible differences in the final sheen of your paint chosen "flashing".

To aid reach a consequent appearance with your final coat, when painting new drywall or over drywall patches it is always a skilful idea to beginning use a primer – and besides, using a quality drywall primer is typically much less expensive per gallon than using multiple coats of a quality interior latex pigment.

Wood Primer

Blank forest is amidst the more difficult substrates for a paint topcoat to attach to. In the past, there was no substitute for a practiced slow-drying oil-based primer on bare woods. It takes a long time to dry, assuasive plenty of fourth dimension for it to soak into the woods, and it sticks meliorate than any other type of primer to forest.

Even though old-fashioned oil primer is nevertheless the best for this use, nobody likes to look 24 hours for a primer to dry earlier they can topcoat it. So the pigment manufacturers have developed new, faster-drying engineering in both oil and latex-based products that dry quickly nevertheless still aid in the proper adhesion of your pigment topcoat.

If you don't mind waiting for the deadening dry time and don't listen the hassle of working with solvent make clean-upward products, we would always recommend oil based woods primer. If you don't want those hassles but have to paint blank woods, it is still worth the time to use a quality latex woods primer before applying your cease coats.

Masonry Primer

Some masonry surfaces tin can have a high pH level which volition cause adhesion issues if you apply paint straight to the surface. A quality masonry primer will allow you to safely paint over a wider range of pH levels without risk of adhesion loss.

Another problem is called efflorescence; which are unsightly white, crystalline deposits that tin can form on whatsoever masonry surface. Many masonry primers are efflorescent-resistant and practise a bang-up chore of keeping information technology from condign a trouble.

Stain-Blocking Primer

Bonding Primer

Some surfaces are especially "slick" and pose a unique claiming for even the all-time primers when trying to get a coating to stick to them. Some examples would be factory coated metal sidings, ceramic tile, glazed block, plastic and vinyl shutters , and surfaces with a high gloss finish.

If you choose the right bonding primer for your application you will exist far more than likely to go great adhesion of your terminate glaze to the surface.

There are a couple of exceptions to these categories:

Multi-Purpose Primers have become very pop because of their universal application for a wide-diverseness of uses. A word of circumspection – some manufacturers have a tendency to oversell these products for situations that they are not necessarily a skilful fit for.
Before you lot grab a multi-purpose primer off of the shelf make sure that it specifically states on the label that information technology tin exist used for your intended purpose. When buying a multi-purpose primer go with a proven proper name brand such as Zinsser , Sherwin-Williams , PPG , or Glidden products.
Paint & Primer In One products are 1 of the newest and most-popular trends in the manufacture. What a great idea! Who wouldn't desire to make their painting project easier past using a production that primes while information technology paints?While this concept is wonderful in theory, it has limited applications when it comes to actually holding upwardly well to the exam of fourth dimension. Again, a good rule of thumb is to stick to the highest-quality manufacturers if you decide to use one of these products, and brand sure you check the label to ensure it can be used for your intended application.

For outside new wood applications, 1 of our favorites is Duration® by Sherwin-Williams.

We would propose people to not call up of these products as something that will save you a coat of primer, merely instead recollect of them as an opportunity to utilize an boosted glaze of the same material instead of switching products between the base glaze and the end coats. On new drywall, you will utilize three coats of the finish textile instead of a primer coat plus two coats of stop.
