Two component waterproofing flexible mortar
EP LASTIK is a two-components water-based flexible mortar consisting of:
EP LASTIK may be applied on both horizontal and vertical surfaces and after curing forms a totally waterproof film with a good elasticity level.
The resulting layer is resistant to attack by thawing or de-icing salts, sulphates and chlorides and protects the substrate against carbon dioxide.
EP LASTIK is used for:
Comp. A: 25 kg bag, on pallets of 56 bags
Comp. B: 7.5 kg can
Two component waterproofing flexible mortar
Preparation of the substrate
Take normal professional care by thoroughly cleaning all substrates in a workmanlike manner and removing loose parts, oil, grease, paint and anything that could prevent correct adhesion of the product.
Special preparations
1.Balconies and terraces:
2.Concrete structures:
3.Plasters:
Preparation of the mix:
EP LASTIK may be applied with a trowel or by mechanical means.
With a trowel, apply a first thin render onto the substrate (wetted if necessary); then apply a second coat wet on wet to obtain a total thickness of at least 2 mm.
If the product is being applied to balconies, terraces, swimming pools, tanks, etc. or to areas subjected to particular stress, insert fibreglass mesh reinforcement (4 x 4.5 mm mesh) RETE DI VETRO 160 between the render and flush second skim coat; wait for the first layer to set before applying a second final coat of product.
By mechanical means, use a spraying machine with skim coat nozzle, taking care not to exceed a thickness of 2 mm per coat.
It is almost always preferable in soffit areas to insert mesh reinforcement since these areas are subject to particular stress: after laying the mesh, go over with a smooth sleeker and apply a second final coat.
Two component waterproofing flexible mortar
It is necessary to apply approx. 1.7 kg/m2 to obtain a film thickness of approx. 1 mm.
