Rust-Oleum American Accents Spray Primer
Best Paint Primer for Plastic
This spray primer is suitable for indoor and outdoor use. It dries in a matte finish in just 20 minutes, and you get 12 square feet of coverage. It adheres to wood, plastic, metal, and unglazed ceramic, so it is a versatile spray primer.
It’s also easy to use and store. Simply pop the lid back on, and it sits on the shelf until you next need it. Rust-Oleum claims that this primer delivers twice the coverage of similar products. They even give you a comfort-grip trigger to reduce finger fatigue.
The only downside with this primer is it only covers small areas, so if you are respraying a chair or plastic components, that’s fine, but not if you want to undertake a significant project.
Also, spray applicators are not as accurate as brushing, so you might get some wastage through overspray.
- Simple to use and easy to store.
- Twice the coverage of similar products.
- Comfort-grip trigger for reduced fatigue.
- Dries in just 20 minutes.
- Only suitable for small projects.
- Lacks accuracy, increasing overspray wastage.

INSL Stix Acrylic Bonding Primer
Best Paint Primer for Drywall
Drywall is extremely porous, so sealing the surface makes the top layer of paint adhere better. While this product covers drywall, it also works on metal, wood, ceramics, PVC, and masonry walls.
It is a water-based product, so it is kinder to the environment, and it has low VOCs, meaning there are no health implications when using this primer. It also has low odors, so you can use it in areas with limited ventilation.
You can also clean up with soap and water. You get 300 to 400 square feet of coverage, depending on the porosity of the surface, and it even cures in temperatures as low as 35 degrees Fahrenheit.
Once down, it dries ready for recoats in just 3 hours, and once you’ve finished priming your drywall, you can take it outside into the garden and prime your deck or furniture.
However, many customers have complained that this primer is too thin, so you are forced to lay down 2 or 3 coats to get a smooth finish.
- Water-based, so better for the environment.
- Coverage of 300 to 400 square feet.
- Recoats in just 3 hours.
- Suitable for indoor and outdoor applications.

You get 300 to 400 square feet of coverage, and it dries ready for a second coat in under an hour. Curing takes 24 hours, and because it is water-based, you get extremely low odors and a VOC level of just 5 grams per liter.
Because it is water-based, it is kinder to the environment, and you can wash everything clean with soap and water. It even features a mildewcide to combat mold growth, so it is suitable in damper locations like kitchens and bathrooms.
One slight negative is the number of coats you need to apply. Some customers have complained they needed 2 or 3 layers before they got a smooth and solid surface to hide any previous colors from showing through.

Best Metal Paint Primer
This Rust-Oleum primer is the ideal product to use if you have bare, painted, or lightly rusted metal. It’s an oil-based formula, so it has excellent rust-preventing capabilities.
It dries to the touch in 2 to 4 hours and covers up to 90 square feet. This primer is ideal for high-use environments, and because it is weather-resistant, it is suitable for indoor and outdoor use.
It is not suitable for bare galvanized metal, and because it is an enamel primer, it has limited coverage. It is also not ideal for large projects. However, it adheres to wood, metal masonry, and concrete, so it is versatile.
The other consideration is its impact on the environment. Oil-based formulas are damaging, polluting rivers and streams and impacting ecosystems. And you need mineral spirits to clean up afterward.
