How to Install Subfloors with Soudabond Subfloor
Timber subfloors in Australian construction require a high-performance polyurethane adhesive. You must use a glue that absorbs the constant movement in timber frame structures. Using the right adhesive strengthens the entire structure. It minimises movement from seasonal expansion and dramatically reduces the chance of squeaky floors over time. Applying adhesive during the installation process significantly increases rigidity and extends the life of your flooring system.
Soudabond Subfloor is a fast-curing PU adhesive designed for these demanding applications. It applies as a foam and then instantly forms a collapsing gel. This unique gel formula fills the small voids between the joist and the floorboard. Those empty voids are the primary cause of floor squeaks. Filling them guarantees a silent and durable subfloor system.
This product changes how you work on site. One single can replaces more than 12 standard adhesive cartridges. You save up to 75 percent of your normal installation time because you are not constantly swapping out empty tubes. It is also water-resistant, mould-resistant, and completely solvent-free. We test it to strict ASTM E84 and ASTM D3498 standards for proven reliability across commercial and residential builds.
How To Install: Step By Step
Gear up: Wear necessary protective gear.
Prep the surface: Make sure the timber joists are clean and free of grease and dust. Spray a light mist of water onto the surface to improve adhesion and speed up the curing time.
Shake the can: Shake the canister vigorously for at least 30 seconds. Repeat this regularly during the job for maximum yield.
Attach the gun: Screw the canister upside down onto your applicator gun.
Set the flow: Use the dial on the gun to control the speed of the foam. Point the nozzle and press the trigger to start applying.
Apply the adhesive: Run a continuous bead directly along the joist. You must place your floorboards onto the wet adhesive within 20 minutes.
Secure the boards: Apply downward pressure to the boards and secure them immediately with additional mechanical fixings like screws or nails.
Clean up: Flush your applicator gun and wipe away any wet adhesive spills using Gun & Foam Cleaner.

FAQs
Why do my new timber floors squeak?
Floors squeak because there is a tiny gap between the timber joist and the floorboard. When you walk on the floor, the board rubs up and down against the metal nail. You can eliminate this completely by using a gap-filling product like Soudabond Subfloor to cushion the joint.
Can I glue subfloors if the timber is frozen?
Yes. Soudabond Subfloor bond perfectly to wet or frozen timber. This makes them ideal for early morning starts in cold climates.
How do I clean up PU adhesive before it dries?
You must use a specialised solvent cleaner. Attach a can of Gun & Foam Cleaner to your applicator gun and flush it through until the liquid runs clear. You can also spray this cleaner directly onto wet adhesive drips to dissolve them instantly.
Do I still need to use screws if I use subfloor adhesive?
Yes. The adhesive prevents squeaks and provides massive structural rigidity. You still need mechanical fixings like screws or ring-shank nails to hold the boards tightly against the joists while the polyurethane cures.
