Types of Adhesive Glue Ideal for Hardwood Floor

One of the most important decisions that you make before you start the installation process of hardwood flooring is choosing the type of glue. If you’re on a budget constraint and you’re opting for the cheapest adhesive, it may entail more cost on repairs in the future. By cutting corners and getting cheap adhesives as what most DIY enthusiasts or the weekend homework would do, which would usually undermine their own efforts.

Types of Adhesive Glue for Hardwood Floors

For the classic wood floors, these are essentially two adhesive glue down product types: (1.) Urethane Adhesive and (2.) Water Based Adhesive Glue Down

Urethane Adhesive

Among all the types used adhesives today, the urethane is the most popular. Generally, if floor companies that manufacture hardwood floor that doesn’t offer their own glue product, they will specify a particular brand of glue. Urethane adhesive is by far more eco-friendly than glues that were used decades ago which are now banned by the EPA, while not the ultimate solution for people looking for a viable solution. Usually, to properly install solid floors, nails are used while glue can be used for engineered floors.

The proper clean-up on the day of installation is demanding if you are opting to use urethane adhesive. For this type of glue,  mineral spirits are the common clean up material.

Water-Based Adhesive

When using glue down adhesives most companies who do installation will tell you that the “plop and slide down method” should not be used. This is because for the DIY, on some occasion, the board may drop down away from the tongue and groove and you will notice that when installing a board. Inserting the board into the groove will nearly fail with the characteristic of the glue when using urethane based glues. When this happens though, the water-based adhesives are far more lenient.

When using water-based adhesives, it usually responds well to the banana effect of some engineered hardwoods which is another benefit. When the wood doesn’t emerge to be completely secured to the subfloor, this is what the banana effect is. There is a little corrective measure that you can take when using urethane adhesive which is the total opposite of water-based adhesive. With water-based adhesive, add a weight to the section that doesn’t perfectly fit. The result then is a stronger, concrete glue-down after drying.
