Prepare Your Subfloor Like a Professional

Correct preparation is essential for a smooth, durable and long-lasting flooring installation.

1. Check for Moisture

Ensure the subfloor is dry and suitable for the flooring system being installed. Where moisture control is required, use an appropriate Liquid DPM before priming.

2. Prime the Surface

Apply Stopgap P131 evenly over the prepared substrate using the correct dilution ratio for the floor type, following the latest F. Ball recommendations.

3. Repair Damaged Areas

Repair surface imperfections using Stopgap Micro Rapid for feather edging and small repairs, or Stopgap 400 Repair for deeper holes and damaged screeds.

4. Choose the Right Levelling Compound

Stopgap Fast-Track 30 – Ideal when installation speed is the priority.

Stopgap 700 Superflex – Flexible formulation for plywood and timber.

Stopgap 1200 Pro – Excellent for refurbishment projects over suitable adhesive residues.

Stopgap 300 HD – Heavy-duty smoothing compound for demanding applications.
