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.
