Plastimul is a solvent-free paste consisting of selected water-emulsified bitumens, special fine-graded aggregates and additives which form a waterproof plastic coating. Plastimul has a thixotropic consistency making it easy to use on flat, curved, vertical and sloping surfaces.
Mapei Plastimul can be used for waterproofing structures below ground level such as foundations, man-made tunnels and underpasses. When completely dry Plastimul will resist re-emulsifying after prolonged immersion in water, even when slightly acid or alkaline and will resist aggressive agents present in soil.
Formulated as a general purpose easy to use bitumen emulsion, Plastimul can be used for waterproofing foundations, bearing walls, underground tunnels and underpasses.
Preparation of the substrate
The surface to be treated must be sound and perfectly clean. Horizontal surfaces (which are then buried or remain below screed level) must have a slope of at least 1% so that water can run off towards the sides or towards drainage points. Remove cement laitance, loose and crumbling parts and all traces of dust, grease, oil and form-release compounds. Before applying Plastimul on masonry in general (bricks, vibro-compressed concrete blocks, etc.), make sure the surface is sufficiently even. Carefully remove from the surface all traces of mortar protruding from between the bricks or blocks and fill any gaps in the joints with Mapegrout Fast-Set rapid-hardening, fibre-reinforced cementitious mortar, Mapegrout Thixotropic shrinkage-compensated, fibre-reinforced mortar or Mapegrout T60 if sulphate-resistant mortar is required.
As an alternative, use sand/cement mortar admixed with Planicrete latex rubber for cementitious mixes. Concrete surfaces, on the other hand, must have no uneven areas or gravel clusters. Repair or smooth over any rough areas with the same products from the Mapegrout line mentioned above. Round off all sharp edges on horizontal and vertical surfaces with suitable power tools, and blend in the areas between foundations and vertical walls by forming a fillet joint made from the Mapegrout product chosen. Seal any breaks in correspondence with structural joints with Mapeband TPE bonded to the substrate with Adesilex PG4.
Waterproofing
First of all, prime the substrate. Dilute Plastimul with approximately 45-50% of water and mix until completely blended. Apply the primer by brush, roller or spray. Alternatively, prime the surface with Plastimul C diluted 1:10 with water, as indicated in the relative Technical Data Sheet. Then apply Plastimul in two layers, as follows: First coat
· When the primer is completely dry, apply a coat of neat Plastimul at least 1.5 mm thick (wet thickness) with a trowel, brush or by spray. Second coat - Spread on a coat of neat Plastimul at least 1.5 mm thick (wet thickness) with a trowel or by spray.
Please note that, to achieve performance levels in compliance with EN 15814 standards (see final performance details in the Technical Data table), at least two coats of product must be applied with a final dry thickness of at least 3 mm.
Protecting the waterproofing layer
When filling the foundation trenches or applying successive protection layers, Plastimul must be dry. The drying time varies according to weather conditions, surrounding temperature, level of humidity, wind, the thickness applied and the type of substrate. Before filling in protect the waterproofed surfaces with suitable protective drainage layers. Only use suitable material for filling in excavated trenches, that is, well assorted material without stones against the protective drainage compacted into a series of layers 40 to 50 cm thick.
