Buyers Guide for the Best Exterior Wood Primer:

Even with our list of the best exterior wood primers, you could get lost and overwhelmed at the billion of options, differing features, and the steeper price tags. All primers have different goals to fulfill but, in order to meet them, they must be applied accordingly. Just like missing pieces to a puzzle. But, how would you know which one’s the missing piece?

Don’t worry. We’ve got you. Our guide will recommend you the essential must-haves and big no’s so that you can find the perfect match.

  • Primer Type: The three types of primers comprising the market are oil-based, water-based, and shellac-based. Oil-based are significantly available and most demanded by users and compliments any wood type. They will inevitably seal holes and pores and create an external barrier to protect the surface. Water-based primers are easy to get rid of; hence, most people get their jobs done with paintbrushes. They also comprise little to no VOC; thus, they’re safer and uncomplicated to clean. Their stain-covering effectiveness isn’t praiseworthy even though they’re made for softwoods, brick, or drywall. Lastly, Shellac-based primers have been serving users for centuries at a stretch. Needless to say, it’s pricier and the best stain coverer. It is rather challenging to apply and clean rather than perform the best for concealing odor or scent.
  • The Odor: Who else hates the pungent scent of primers and paints? Say – aye! Unfortunately, just hating that bit isn’t enough. It also comes with a price. These odors are usually highly toxic, even more, if you have children and pets around. It’s sensible to opt for primers with low to zero odor percentage. As these pose lower chemical rates, it’s safer too.
  • Toxicity Levels: Dealing with primers or paints will indefinitely have some levels of toxicity involved. However, besides grabbing a non-toxic primer, you could also ensure all the safety conditions and continue with the process. Non-toxic primers are never at a level-zero of toxicity but, they’re less hazardous to your health.
  • Coverage: It’s smarter to judge your area of the project before heading out to purchase a primer. Simply, to not waste the primers or paints later on. You can confirm and cross-check with the primer’s coverage label and choose accordingly. It’s smarter to grab a tad more than you initially need but, try to keep it at a ‘tad bit’ and not excessive.
  • Drying Duration: Like any other case, primer drying times diverge from one another. The time limits could be drastically different as 10 minutes or even 24 hours. However, you need to be the judge of that. How fast do you need the primer to settle down? For projects that need to be completed within a day, opt for the shortest drying time and the opposite if you’re in no hurry.
  • Finish: What kind of polish do you desire to achieve? Glossy, or perhaps matte? Whichever type of finish you choose will not affect the quality or lifespan of the primer. Thus, you’re free to reincarnate your wood at your will.
