How to Smooth OSB Board: A Comprehensive Step by Step Guide

How smooth the OSB board is a tedious process that requires patience and dedication. You should take your time to do it right, or you will end up with a terrible result. Also, make sure to use the right tools for the job, to avoid having a lot of problems.

To smooth OSB board, you’ll need to sand the surface of the board, apply a layer of primer, paint the board, and seal it. You can do this by using a clean cloth to wipe away any excess joint compound. Allow each coat to dry thoroughly before applying the next one. Once you’re finished, you should have a smooth, sealed OSB board that’s ready for use.

What is OSB Board?

OSB board is an engineered wood product. OSB boards are made by shredding pieces of timber and then pressing them into panels. These panels have a high number of voids which can cause problems for finishing purposes. For this reason, smoothing OSB boards requires some extra effort compared to other types of hardwood floors.

Why is it Important To Smooth OSB Board?

If you have installed an OSB board, then you know how hard it is to work with. The edges are sharp and the surfaces can be uneven. If your project requires a level floor or if you plan on installing an expensive type of flooring over top, then smoothing the OSB boards is necessary for a quality result.

Uses of OSB Boards

OSB boards are used for a variety of purposes. These include:

• Wall paneling
• Floor decking boards
• Roof sheathing on houses and warehouses
• Wall sheathing on garages, house additions, greenhouses, and other structures

Tools You Will Need:

• Sander

A belt sander is the most common tool used to smooth the OSB board. This machine will remove excess pieces of wood and create a flat surface on your boards.

• Adhesive

The best type of adhesive to use is a solvent-based one. This will bind the OSB board together and create a strong, durable bond between your floorboards.

• Primer

An oil-based primer will help to smooth the OSB board and create a barrier between the OSB boards and your paint.

• Spray Paint

Use oil-based spray paint to smooth the OSB board. This will create a hard, durable surface that is resistant to scratches and scuffs.

• Sand Paper

Use coarse sandpaper to smooth the OSB board. Start with the 220 grit and work your way down until you achieve a smooth surface.

• Paint Brush

Use a paintbrush to smooth the OSB board. This will help you get into the corners and hard-to-reach places of your boards.

• Rags

Use rags to smooth the OSB board. This will remove excess paint and other liquids from the surface of your boards.

• Shop Vacuum

Use a shop vacuum to smooth the OSB board. This will remove all of the dry, excess sawdust from your boards.

• Float

A float is used to smooth the OSB board. This will help you achieve a smooth finish on your boards.

• Paint Tray

Use a paint tray to smooth the OSB board. This will help you mix your primer and paint in the right ratio for application.

• Roller Frame

A roller frame with a foam pad is used to smooth the OSB board. This tool applies even pressure across large areas of your boards.

• Nylon Brush

A nylon brush is used to smooth the OSB board. This tool will help you apply the paint evenly across your boards.

• Paint Tray Liner

Use a paint tray liner to smooth the OSB board. This will make clean-up easy and efficient. Once you have finished smoothing OSB, it can be sanded using an orbital sander and shaped using a floor sander.

• Paint Scraper

A paint scraper is used to smooth the OSB board. This tool helps you remove any excess material from your boards.

• Floor Scraper

A floor scraper is used to smooth the OSB board. This tool helps you remove excess adhesive from your boards.

• Dust Mask

You will need a dust mask when smoothing OSB because the sawdust created by sanding can be harmful if it gets into your lungs.

• Gloves

When smoothing the OSB board, you should wear gloves.

• Eye Protection

When smoothing the OSB board, you should always wear eye protection.

• Respirator

When smoothing the OSB board, you should wear a respirator.

How to Smooth OSB Board: Step-by-Step Guide

Step One: Marking Out  

Mark out areas on your floor where the new boards will go. Use a chalk line to mark these spaces and snap a straight line along all of them.

If you plan on using an adhesive, stick down one strip in each section that requires new board installation. Make sure there is enough adhesive to cover an area slightly larger than the board itself.

Step Two: Apply Adhesives

Apply a strip of adhesive in each section that requires new boards. Use your paintbrush to smooth out any excess bubbles.

This will take 24 hours for your floor to dry, so it’s best if this is done over a weekend while nobody is going to be in the house.

Step Three: Sand The Edges

Use an orbital sander to smooth out any rough edges or imperfections on your new floorboards.

Run the machine along these sections until you achieve a consistent, level surface across all of them.

This will take some time and patience, but it’s important that you do this step correctly for safety reasons.

Step Four: Shaping The Boards

Use a floor sander to shape your new boards. This will help you create more defined edges and corners. A floor sander is the only way to go here because they are designed for this specific task.

Once you have finished shaping them with your machine, smooth out any rough patches or areas where the material has been removed.

Step Five: Get Rid of Excess Adhesive

Use a floor scraper to remove excess adhesive from your new boards. This will help you maintain the integrity of each board, making them easier to clean in the future.

You might need to use some elbow grease with this step if there is any tough material stuck on it. A small flathead screwdriver can be an effective tool to help you remove any stubborn pieces.

Step Six: 

Use a paint scraper to smooth out your new boards. This will help you create uniform borders around each board that are ideal for painting.

Make sure not to miss this step since it’s important for proper adhesion of the primer and paint, getting a good-looking final result.

Step Seven

Wear a respirator, gloves, eye protection, and ear protection. This is important because the dust created from sanding can be harmful if it gets into your lungs or eyes.

It’s also crucial for safety reasons so you don’t damage your hearing when using loud power tools at high volume.

Step Eight

Use a paint tray liner to smooth your new boards. This will make clean up easy and efficient for you. Once you have finished smoothing out the boards, they can be sanded using an orbital sander and shaped using a floor sander.

Step Nine

Remove excess adhesive using a floor scraper. Make sure there is no residue left behind, otherwise it will stick to your paint and ruin the final result.

This can be time-consuming because you need to make sure each board has been fully cleaned before continuing on to the next step.

Step Ten

Tape off sections of your board that you don’t want to be painted. This will help minimize the amount of paint you use and get a better overall result.
