strips of fabric by at least 10 cm and press the fabric with a flat trowel
to make sure it is perfectly buttered. Please note that the first layer
of product must be applied in pitch areas wider than 1.2 metres, so
that when MAPETEx SEL (width 1 metre) is applied, there will be at
least 10 cm per side of MONOLASTIC or MONOLASTIC ULTRA to
guarantee that it forms a continuous layer when the next pitch of product
is applied. 2 hours after applying the first layer in good weather, and in
all cases never before the first layer has completely dried, the second
layer may be applied. Make sure the second layer completely covers
the mesh, and finish off the surface with a flat trowel. After completing
the application cycle of MONOLASTIC or MONOLASTIC ULTRA,wait
at least 2 days before installing the tiles.
FOR READY-TO-USE PRODUCTS
MAPELASTIC AQUADEFENSE is supplied ready to use and does not
need to be mixed. Apply with a long-haired roller, brush or trowel in two
even layers at around 0.4 mm thick per coat for a final thickness of at least
0.8 mm in order to create a robust, flexible continuous film. Make sure there
are no interruptions in the film caused by imperfections in the substrate.
After applying MAPELASTIC AQUADEFENSE wait approximately 4 hours
for curing and then lay the ceramic tiles. Before tiling, carefully check the
surface of MAPELASTIC AQUADEFENSE to make sure it is continuous
and that there are no pin-holes or small craters. If there are such defects,
apply a further coat where they are located. For indications regarding laying
tiles and grouting and sealing joints, please refer to sections 8 and 9.
