Instructions

Mixture
  • If necessary, mix the insulation before use.
Pretreatment of the base
  • The base must be dry, dust-free and level, solid and immobile, and free of substances that reduce adhesion
  • Remove any cement paste and weak or eroded surface
  • The recommended moisture of the base is <85% RH, and the maximum moisture is <90% RH
  • Level uneven floors with Fescon Floor Levelling Compound and walls with Fescon Levelling Compound for Wet Areas WTT
  • Treat the bases with Fescon Primer KP according to the instructions
  • Switch underfloor heating off two days before waterproofing
Spreading the waterproofing compound

The temperature of the room and the base must be +10 - +30 °C. The working conditions must remain constant throughout the entire work.

Spread the waterproofing compound first into corners, joints, lead-throughs and around the floor drain. Fasten a reinforcement strip in these locations using a brush or a roller. Make sure that the strip is wet throughout. Place a 40 x 40 flexible drain flange around the floor drain. Do not apply waterproofing compound inside the floor drain.

Next, apply the waterproofing compound to the entire area to be treated. Allow to dry for 3-4 hours, depending on the conditions at the worksite. After drying, the waterproofing compound is blue in colour. Apply a second layer of the waterproofing compound. Allow to dry for five hours before beginning to lay tiles. Cut a hole at the floor drain with a diameter 40 mm smaller than the drain diameter, fold and clamp the membrane to the inner surface of the drain using a clamp ring. Wash tools and equipment with water immediately after completing thee work.

A sufficient minimum dry film thickness can achieved by a usage of approx. 0.7 l/m2 (min. 1,0 kg/m2)The dry film thickness must be min. 0,5 mm.
