Buyer’s Guide

There are numerous different types of spray primers, each one giving the user a different result with each use.

As we have seen, there are primers with highly heat-resistant properties, as well as ones that help stop corrosion and fill in all the imperfections in your wood or metal surface.

One thing that you’ll want to consider before purchasing your next primer is what surface you’ll be working with.

Will you be spraying car metal or lacquered wood? Each type of surface material will differ depending on what you want to use it for.

It’s important to look at what your primer has to offer you before buying, so you don’t buy something that isn’t up to scratch:

Oil-Based Primers

These types of primers are amongst the most popular and have been used by professional carpenters and mechanics for decades.

This is because they are extremely durable and have the ability to be applied to many different types of surfaces. You can also use them on the exterior and interior of various objects such as engine parts.

Using these kinds of primers for metals is perfect, as they give you that strong coating that you can paint over easily and quickly.

These primers also fill in any imperfections, so if you have any restoration work that needs doing, then we would recommend that you use an oil-based primer.

The Downsides Of Primers

A lot of these primers do give off a noxious gas that certainly won’t be pleasant to the nostrils.

The chemicals that are inside one of these volatile compounds can be very harmful to ingest, which might be particularly dangerous if you are surrounded by children and animals.

Be wary that these primers are getting sprayed, so a lot of these chemicals will be sprayed into the air around you as your use them. So it will be paramount that you have the right level of protective equipment with you as you apply them.

Make sure that you use goggles to protect your eyes, as getting any of these chemicals in that area could result in blindness. You’ll also need gloves to protect the skin and a ventilated mask so that they do not enter your respiratory system.

You’ll also need to be sure that your spray work has had enough chance to off-gas. This might take anywhere between a few hours to a day or two.
