1.Vacuum

Vacuum your hardwood floors thoroughly with a machine designed for hardwood floors.

Remember, your floors don’t count on a protective finish just yet, be extra careful with the elements used to clean prior to the application.

Clear all of the dust bunnies and reach into the tighter corners to remove any dust. Open doors and windows for some airflow and to allow the rooms to breathe.

Make sure you start with the thickest paper and work your way down to 220-grit sandpaper

But don’t spend too much time in a single area. Or else you will score the wood.

FAQ

How Many Coats of Polyurethane Should You Apply To Hardwood?

Best practices say to apply at least 3 coats of polyurethane and sanding between coats and allowing the floor to dry off.

Some finishers will allow for a lower number of coats. If you want the maximum level of protection, I suggest you do 3.

Remember that scratches easily reach the surface and ruin the floor if not thoroughly protected.

So, ensure the protection of your floor and save future money on refinishing by applying more than two coats.

How Polyurethane Works?

Due to this finish, you ensure that my hardwood floors are protected. It safeguards the wood flooring from spills, scratches and everyday traffic.

You purchase polyurethane in 2 types and has a few levels of sheen, which range from matter to glossy.

You can apply urethane yourself by following a few instructions.

However, before attempting to apply a polyurethane finish, there are a few considerations to keep in mind.

  • How much money are you saving on this DIY project?
  • Are any skills you don’t count on that may cause accidents?
  • Should you hire a professional in spite of wanting to undertake the application on your own?

If any of these questions spark doubt, consider calling a professional for quotes and advice.

What Is The Difference Between Oil-Based VS. Water-Based Polyurethane?

Before getting to work, decide which polyurethane type you want to apply.Both oil-based and water-based will protect hardwood. And this, no matter if you installed engineered hardwood or traditional.However, there are some differences worthy of pointing out.

1. Water-Based Polyurethane that is water-based layouts clear. It does not modify the original color of the wood.This solution is thinner compared to others and dry much quicker. Within 8 to 12 hours of application, you will be able to walk freely on your floors.This type of finish doesn’t contain harmful VOC’s (2) and is less flammable compared to oil-based polyurethane.

If you’re not a fan of strong fumes and odors, and I get it, then, water-based is the right choice.It terms of cleaning up after the job, you only need water and soap. Nevertheless, this polyurethane type of less durable and more expensive.For maximum protection, you need to apply several coats of urethane. This because the urethanes are composed of fewer solids.And for those that seal wood floors with water-based polyurethane, they will need to repeat the process at least every 2 years.

2. Oil-Based Polyurethane: Oil-based urethanes boost the wood’s natural color. They offer a gentle glow.But, oil-based products have longer drying time and are thicker due to their composition. These will definitely emit fumes, you will need a respirator.

A considerable advantage of this urethane type is the way it fortifies the wood with a more solid layer of protection.Compared to water-based polyurethane, oil-based will take a fewer number of coats, But cheaper. With that, it’s time to learn more about the supplies, tools and costs.
