MIXING
- The 2 components must be mixed using a slow speed machine mixer (300-500 rpm).
- Follow the instructions below to ensure a homogenous mixture:
- Pour ¾ of the resin into a suitably-sized container.
- Add the powder gradually while mixing in order to obtain a plastic consistency
- Add the rest of the liquid and mix for 3 minutes. - Leave to stand for 2 minutes.
APPLICATION
- LANKO® 226 Flex can be applied by hand with a brush or trowel.
- Apply a 1st coat allowing a rough but reasonable quantity of 1.5 to 2 kg/m².
- The 2nd coat can be applied after a drying period of 2 to 6 hours (temperature dependent), allowing a quantity of 1.5 to 2 kg/m².
- The total thickness of the covering should be approximately 2 mm, and never less than 1.5 mm.
- Mortar must be used within 40 min of preparation (at 25°C).
REINFORCEMENT
- For substrates subject to micro-cracking, the 1st coat should be reinforced with LANKO GLASS FIBER MESH.
SUITABLE COVERING MATERIALS
- LANKO® 226 Flex can be covered with tiles within a period of 3 days minimum to 7 days maximum after application of the final coat (bonded with tile adhesive, DAVCO SUPER TTB or DAVCO ULTRAFLEX) or a cement mortar screed.
- High-traffic areas should be protected against abrasion.
- Reservoirs and tanks can be filled after 7 days drying time.
