Stopgap 1200 – High Performance Smoothing Compound - Powder and Liquid SET (contact us if you need to buy separate kits of Liquid only or Powder only)

Stopgap 1200 is a two-component, low-odour smoothing compound engineered for fast, efficient preparation of internal subfloors before new floorcoverings. Mixing a specially formulated powder with Stopgap 1200 Liquid, it delivers a smooth, stable base that sets quickly—ideal for time-sensitive projects. 

Key Features & Advantages

  • Walkable after 60 minutes, with most floor coverings ready to lay in just 4 hours when applied at 2-3 mm.

  • Works direct over old adhesive residues (including bitumen and carpet tile tackifiers) without priming. 

  • Moisture tolerant—can be used over damp, clean, and uneven concrete or screeds. 

  • Fills from 2-10 mm unfilled; can be built up to 30 mm when filled with aggregate. 

  • Marine-approved for use in shipping or marine flooring applications. 

Coverage & Application

  • Approximately 5.0 m² per 20 kg unit at 2-3 mm thickness. 

  • Ideal for use in sensitive environments like hospitals or clean rooms due to its protein-free, low odour formulation.
