Oil-Based Primer Buyer’s Guide

best oil based primer

If you’re a newbie, as such confused on what to consider before buying the product, our buyer’s guide will give you all the relevant information you need. All the same, if you’re a professional painter, this guide should serve a refresher.

Stain Coverage

One of the exceptional features that you’ll find in contemporary primers is the ability for a single coat to cover stains and prevent them from affecting the topcoat.

However, paint tells an entirely different story. Paints can cover up stains but not as consistent as an oil-based primer, especially when they’re of low-qualities.

Therefore, find a primer that can cover up stains efficiently while providing a consistent base for durable adhesion.

Also, it’s preferable to wipe off some stains instead of covering them up. Primer is good at what it does, but keep in mind it can’t repair structural damage.

For this reason, ensure you take care of the severe problems before applying the solution.

The capability to lock in smell is another crucial feature you should consider before buying the product. Although we all know how VOCs oil-based primer smells can be, it’s their true nature.

However, most manufacturing companies are coming up with a low-smelling formulation that is not too offensive.

So if you’re sensitive to smell, you may consider opting for a low odor solution that can still block smells that have accumulated in your material.

Drying time

Most brands claim their primer dries within 30 minutes or an hour. It’s only partially true.

We’re all aware of oil-based dries lowly because of the ingredients that they have. Despite any company’s promises of quick-drying time, it’s advisable to wait 24-48 hours after you apply the primer. In that case, it results in a better bond.
