Buying Guide

When it comes to choosing the best exterior primer, there are a few key features to look for. Here are some factors to consider before making your purchase:

Surface Type

The type of surface you will be priming is an important factor to consider. Different primers are designed to work best on certain surfaces, such as wood, metal, or concrete. Make sure to choose a primer that is compatible with the surface you will be priming to ensure the best results.

Coverage

Coverage refers to how much area a single can of primer can cover. This is an important factor to consider, especially if you have a large surface area to prime. Look for a primer that offers good coverage without the need for multiple coats.

Drying Time

The drying time of a primer is another important feature to consider. Some primers dry quickly, while others take longer to dry. If you need to prime a surface quickly, look for a primer that dries fast. However, if you have more time to work with, a slower drying primer may be a better choice as it can provide a smoother finish.

Weather Resistance

If you live in an area with harsh weather conditions, it's important to choose a primer that can withstand the elements. Look for a primer that is designed to be weather-resistant, as this will help ensure that your paint job lasts longer.

VOC Content

VOCs (volatile organic compounds) are chemicals that can be harmful to the environment and to human health. Look for a primer that has a low VOC content to minimize your impact on the environment and to reduce any potential health risks.

By considering these factors, you can choose the best exterior primer for your needs and ensure a successful paint job.
