5-Step Guide: How to Install 1.8cm PP Interlocking Garage Floor Grates | No Glue & No Cement Needed

June 3, 2026

In this step-by-step guide, we’ll show you how to install your 40×40×1.8cm PP floor grates in just 5 steps.

Step 1: Prepare & Clean the Ground

Start with a flat, dry, clean surface.

· Sweep away dust, dirt, gravel, and debris.

· Remove oil stains or wet spots (dry completely).

· Check for bumps or cracks—level small uneven areas if needed.

A clean base ensures the grates lock tightly and last longer.

Step 2: Plan Your Layout

All our tiles are 40×40×1.8cm, fully interchangeable.

Tips:

· Start from a corner or straight edge (wall/door).

· Mix hollow drainage grates in wet zones (washing bays, poolside).

· Use solid anti-slip covers in dry zones (entry, showroom, gym).

· Leave a small gap along walls for thermal expansion (prevents buckling).

You can cut edge tiles easily with a utility knife or jigsaw for a perfect fit.

Step 3: Snap the Tiles Together

This is the easiest part—tool-free interlocking design.

1. Place the first tile flat on the ground.

2. Align the male/female edges of the next tile.

3. Press down firmly until you hear a click—it locks securely.

4. Continue row by row, left to right, front to back.

No glue, no nails, no mess. Just snap and go.

Step 4: Install Edge Trims (Optional)

For a neat, finished look, add edge strips around the perimeter.

· Edge trims hide raw tile edges.

· Protect tiles from lifting or tripping.

· Give your floor a professional, polished finish.

Step 5: Finish & Enjoy Your New Floor

Once all tiles are locked:

· Walk over the floor to check for loose connections.

· Adjust any misaligned tiles.

· Rinse the floor lightly to remove dust.

Done! Your new 1.8cm PP interlocking floor is ready for use—park cars, wash vehicles, walk, or work immediately.
