Where to use

Waterproofing and protection of concrete structures, renders and cementitious screeds.

Some application  examples

•  Waterproofing of concrete basins used for containing water.

•  Waterproofing bathrooms, showers, balconies, terraces, swimming pools, etc. before laying ceramic tile  finishes.

•  Waterproofing of plasterboard, render or cementitious surfaces, lightweight cement blocks and marine-grade plywood.

•  Flexible smoothing layer for light-sectioned concrete structures, including those subjected to minor deformation when under load (e.g. pre-cast panels).

•  Protection of renders or concrete with cracks caused by shrinkage, against the infiltration of water and aggressive atmospheric elements.

•  Protection, against the penetration of carbon dioxide, of concrete pillars beams and road and railway viaducts repaired with products from the Mapegrout range, and structures with an insufficient layer of concrete covering on the reinforcement rods.

•  Protection of concrete surfaces which may come into contact with seawater, de-icing salts, such as sodium or calcium chloride, and sulphates

Preparation of the mortar

Pour component B (liquid) into a suitable, clean container, then slowly add component A (powder) while stirring

with a mechanical mixer.

Carefully mix Mapelastic for a few minutes, making sure that no powder remains stuck to the sides or the bottom of the container.

Keep stirring until a perfectly homogenous mix is obtained.

Use a low-speed mechanical mixer for this operation to avoid too much air being dragged into the mix.

Do not prepare the mix by hand. Preparation of Mapelastic may also be carried out with a mortar mixer, which is usually supplied with mortar sprayers.

If this technique is used, make sure that the mix is homogenous and has no lumps before it is poured into the hopper of

the pump.

  CONSUMPTION

Manual application:

approx. 1.7 kg/m² per mm of thickness. Spray gun application:

approx. 2.2 kg/m² per mm of thickness.

STORAGE

Mapelastic component A may be stored

  for up to 12 months in its original packaging.

Mapelastic component B may be stored up to 24 months.

Store Mapelastic in a dry place and at a temperature of at least +5°C.
