Application Details

  • Mixing: Stir before use with a flat paddle to an even consistency. Stir occasionally during use.
  • Method: Roller, brush.
  • Thinning: Water if required to a maximum of 10%.
  • Cleaning: Remove as much of the product as possible from the application equipment before cleaning with tap water when wet, ProGold Lacquer Thinners when dry.

Conditions:

  • Temperature between 5°C and 40°C.
  • Relative humidity of less than 85%, preferably between 10: 00 and 16: 00. Ideally apply when the temperature of the substrate is at least 2°C above dew point.
  • If possible away from direct sunlight.

Drying time: 
4-6 hours at 23°C. 
Note: 
 Higher temperatures will accelerate the drying times (approximately halved for every 10°C increase), whilst lower temperatures will retard the drying time (approximately doubled for every 10°C decrease).

Recoating time:
 24 hours if used to saturate the ProGold Membrane. 6 hours as a topcoat over the saturated ProGold Membrane at 23°C.

Requirements:
 Two coats when used on saturated waterproofing membranes. Three coats if used to saturate the ProGold waterproofing membrane.
