How to Choose the Best Sealant for Wood Playsets

How to Choose the Best Sealant for Wood Playsets

You don’t want to waste your money on a subpar sealant that won’t do the job properly. Here are a few things to keep in mind when choosing the best sealant for your wood playset:

Durability

You want a sealant that will last for many years, even if it costs a bit more upfront. While you may not always tell if a product will last by just looking at it, it helps to read reviews from other customers and see what they have to say.

Ease of Application

You don’t want to choose a sealant that is too difficult to apply. If it’s hard to spread evenly, likely, you won’t get full coverage and your playset won’t be properly protected. Look for a sealant that goes on easily and dries quickly.

Type

There are two major types of sealants: water-based and oil-based. Water-based sealants are easier to apply and clean up, but they don’t last as long as oil-based sealants.

Oil-based sealants provide better protection, but they can be a bit more difficult to work with.

Note also that the type of sealant you buy will depend on the type of wood your playset is made of. If you’re not sure, it’s always best to ask a professional or consult the manufacturer’s recommendations.

Stain

What color do you want your sealant to be?
Many people prefer to first coat the paint with a clear sealant so that the natural color of the wood can still show through.

Others like to use a tinted sealant to give their playset deck a bit of extra personality. You want to make sure that the stain you choose will be compatible with the type of wood your playset is made of.

Transparency

This is similar to the point above, but it’s worth mentioning separately. Some sealants are completely opaque, while others are transparent.

If you want the natural color of the wood to show through, you’ll want to choose a transparent sealant and paint brushes to apply it.

UV Protection

While all sealants will protect your wood playset from the elements to some extent, you may want to choose one that offers extra UV protection. This is especially important if your wooden playset is in a sunny location.

Customer Reviews and Ratings

Be sure to read reviews from other customers before making your purchase. This will give you a good idea of what to expect in terms of quality and performance.

It’s also helpful to look at ratings, as this can give you a quick overview of how satisfied people are with a particular product.

Drying Time

The drying time will vary depending on the type of sealant you choose. Water-based sealants usually dry relatively quickly, while oil-based sealants can take a bit longer.

Keep this in mind when making your selection so that you can plan accordingly.

Verdict Seal-Once Nano+Poly is the most versatile sealant here.
