Fix-A-Floor® Injection Repair Adhesive – Step-By- Step Application Guide

This guide walks you through the proper surface preparation and application process for repairing hollow or loose tiles and planks using Fix-A-Floor® Injection Repair Adhesive. Follow each step closely for optimal bond strength and performance.

Surface Preparation

Locate the Problem Area

Use a wooden dowel or tool handle to gently tap along the flooring, listening carefully for a change in sound—a hollow or dull tone indicates a void beneath the tile or plank.
Once located, mark the perimeter of each affected area using painter’s tape or chalk to guide your drilling and adhesive application.

Drill Injection Holes
- Recommended drill bit sizes:

Using a masonry or standard drill bit, drill 1–2 holes straight down on each side of the affected tile or plank.
Always drill within the grout line to preserve the appearance of the flooring and prevent damage.
Carefully avoid making contact with the tile surface or subfloor.

Clean Out Debris

Use a vacuum over each drilled hole to remove loose dust, debris, or particles.

While vacuuming, lightly tap the area with a rubber mallet to further dislodge hidden debris and ensure a clean cavity for adhesive bonding.

Application Instructions

Prepare the Cartridge
- Remove the cap from the Fix-A-Floor® cartridge.
- Cut the nozzle tip so that it fits snugly into the drilled holes—avoid cutting too wide, and ensure it does not touch the subfloor when inserted.
- To open the cartridge for use:
  - Unscrew the nozzle from the threaded cartridge nub.
  - With a utility knife, cut an opening directly above the cartridge nub thread line.
  - Screw the nozzle back on securely and keep the cartridge upright to prevent premature flow.
Apply the Adhesive
- Load the prepared cartridge into a full-framed caulk gun (8:1 to 10:1 thrust ratio).
- Insert the nozzle firmly into the first drilled hole and begin slowly dispensing the adhesive.
- Continue applying until adhesive visibly overflows from adjacent holes—this ensures the cavity is completely filled.
- Repeat for all drilled holes in the marked area, taking care to avoid adhesive drippage when moving between holes.
Set and Cure
- Immediately wipe away excess adhesive using a damp sponge or cloth.
- Place a 20-pound weight (such as a bucket of water, stack of books, or tool case) on the repaired area to help the flooring bond evenly.
- Clean up any additional overflow that may occur and allow the adhesive to cure undisturbed for a minimum of 24 hours.

Fill and Finish

After the adhesive has fully cured, fill each drilled hole with matching grout (for tile) or wood filler (for plank).
Smooth the filler flush with the surface and allow it to dry completely.
Once dry, wipe the area clean with a dry cloth to restore the floor’s appearance.
For any remaining adhesive haze or buildup, use Fix-A-Floor® Adhesive & Residue Remover following label directions.

For Best Results

Fix-A-Floor® Repair adhesive is NOT recommended for use on floating floor systems that utilize click-lock edges or underlayment. It can be used to repair glue-down laminate and luxury vinyl flooring. Ensure the product is tested in one repair area first before applying it to others.
Not recommended for use on carpet ﬂooring.
Use Red Devil® Revolving Barrel Caulk Gun (3988) or similar half-barrel/full-framed 8:1 to 10:1 thrust ratio caulk gun. Avoid using a skeleton-frame caulk gun for application.
Ensure to apply Fix-A-Floor® Injection Repair Adhesive slowly when using the Fix-A-Floor® Micro Injection Nozzle. This will help prevent any unnecessary adhesive blowout.
Ensure the tile floor is installed properly using adequate expansion joints. Stress on the tiles will limit the success of this product.
When repairing heated floors, ensure heating elements are turned off for 48 hours before, during, and after application.
When repairing bathroom & shower tile, ensure subfloor is free of moisture before application and surface is adequately sealed after adhesive has fully cured.
Can be used as a general flooring adhesive to reattach entirely removed tiles or planks.
Recommended for minor wood floor applications. For large-scale wood floor applications, use Fix-A-Floor® Polyurethane Wood Floor Repair.
