Waterproofing and protection of
concrete structures, renders and cementitious
Some application examples
concrete basins used for containing water.
Waterproofing bathrooms, showers, balconies, terraces, swimming pools,
etc. before laying ceramic tile finishes.
plasterboard, render or cementitious surfaces, lightweight cement blocks and
• 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)
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
approx. 1.7 kg/m² per mm of thickness. Spray gun application:
approx. 2.2 kg/m² per mm of thickness.
component A may be stored
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
