Thistle GypPrime

Thistle GypPrime

Primer to reduce suction on very dry backgrounds.

A suction control primer to give a lower suction base on very dry backgrounds. Applied by roller or brush onto the background, this can then be plastered when it has soaked into background and has dried. Yellow in colour to aid identification of treated areas. Typical coverage needed for 100m² is approx. 11 litres undiluted. 11 litres can also be diluted to give 300m² of coverage at a ratio of 1:2 and 600m² at a ratio of 1:5 with fresh water.

British Gypsum - Who we Interviewed

  • Lengthens the working time of plasters on very high suction backgrounds by helping them retain water, and minimises potential for adhesion failure caused by rapid dry-out
  • Yellow in colour - easy to avoid missing any areas
  • Can be diluted - normally 1 part to 5 parts water provides adequate suction control, or can be used neat if necessary to control extremely severe suction
  • One tub covers up to 600 sq.m (diluted 1:5) or 100 sq.m undiluted
  • Easily applied by suitable roller, brush or spray 
  • Large container allows application directly from the tub
  • Helps to consolidate dusty backgrounds
