Description

Larsen Rapid Tank 360 is an easily applied, fast-setting, flexible two-part sealing slurry (powder and liquid) with excellent bond to mineral surfaces. It sets non-shrinking and crack-free, and is watertight against both positive and negative water pressure. Supplied as a 10kg pack in grey, for internal and external tanking.

Key properties

  • Two-part slurry: Part A powder mixed 1:1 with Part B liquid
  • Rapid curing and highly flexible. Bridges gaps and joints up to 1mm, even at lower temperatures
  • Watertight against positive and negative pressured water
  • Permeable to vapour diffusion, impermeable to chlorides, resistant to frost and ageing, and an effective CO2 barrier
  • For screed and heated screed, concrete, masonry, aerated concrete and plasters
  • Wet rooms (walls and floors), terraces and balconies, swimming pools, water tanks and cellar sealing, and protecting concrete against carbonation
  • Application temperature +5°C to +30°C

Coverage

The datasheet gives consumption of approximately 1.3 to 1.6kg/m² per mm of layer thickness.

Working and drying times

  • Pot life: approximately 45 minutes at 20°C. Use the mixed material within 45 minutes, and do not add water or liquid once it has started to set
  • Time between coats: minimum 90 minutes
  • Covering possible: after 4 hours. Ceramic tiling after 4 to 5 hours
  • Walkable: after 24 hours
  • Exposure to water pressure: after 3 days
  • Shelf life: 6 months unopened, stored dry and protected from extremes of temperature

Drying depends on temperature, air movement, humidity and layer thickness. Outdoors, protect the coating from heavy sunshine at higher temperatures while it hardens.

Preparation

The surface must be solid, supportive, free of gypsum and widely level, with oil, grease and other separating layers removed. Fill pockets of loose gravel, pinholes and uneven areas with a mineral filler. Pre-wet the surface thoroughly so it is slightly damp, with no puddles. Residual moisture must not exceed 2.0% for cement screed, 0.5% for anhydrite screed and 0.3% for heated anhydrite screed.

Application

Mix the powder for each coat 1:1 with the liquid in a clean pail until lump-free. Apply richly and evenly with a hard brush, wide paint brush, spatula or suitable spray device. Do not modify the slurry with other additives. Protect the fresh coating from rapid water evaporation, extreme heat, draughts, frost and rain. Where joints or gaps are wider than 1mm, reinforce with fleece tape pressed into the first coat while it is wet and tacky, then apply the second coat after 90 minutes.

Safety

The powder component contains cement and is irritating to eyes and skin. Avoid inhaling dust and contact with eyes and skin, and wear suitable gloves. The liquid component is not classified as hazardous. Consult the safety data sheet before use.
