Application

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:

• treat the angle fillets and joints as described in the instructions for use of BETONGUAINA and BETONGUAINA.S; seal the cracks with NORPHEN RICRETE;
• alter the pitch or slope (if necessary) with GROVE MASSETTO and GROVE PRIMER;
• abrade the surface of tiles with BOSCH GBR 14 CA grinder, or wash with NORDECAL FORTE. Wet absorbent surfaces with water.

2.Concrete structures:

• remove any cement laitance by specific abrasion; wash with water under pressure; damaged surfaces must be scarified and made good with products from the CONCRETE REPAIR range;
• wet absorbent surfaces with water.

3.Plasters:

• leave to cure for 1 or 2 weeks according to the thickness; if necessary consolidate with NORPHEN SW SOLID diluted 8-10 times in water and wait 2 days;
• wet absorbent surfaces with water.

Preparation of the mix:

• pour EP LASTIK comp. B into a suitable working container and add EP LASTIK comp. A while stirring continuously; mix thoroughly using a low speed mixer (500÷600 rpm);
• mix until a smooth lump-free mix is obtained.

Product application

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.

Average Consumption

It is necessary to apply approx. 1.7 kg/m² to obtain a film thickness of approx. 1 mm.

Features

Note: test methods are in accordance with the standard referred to in the table.

Warning and informations

• Do not apply onto substrates that are too warm due to a high summer temperature: in this case wet the substrate with water to lower the temperature and apply if possible in the afternoon.
• Do not apply onto surfaces that are frozen or could freeze within 24 hours after application.
• Do not apply with a single coat thickness exceeding 2 mm.

• Wait for approx. one week before tiling over the product.
• Apply at a temperature between +5 and +35°C.
• Foot traffic: 24÷36 hours.
• Complete curing under normal conditions: 7 days.
• The product is not dangerous: a safety sheet is, however, available.

Preservation

Comp. A: 12 months in the original packaging, in a sheltered, dry place, at a temperature between +5°C and +35°C; the product must be protected against damp.

Comp. B: 24 months in the original packaging, in a sheltered place, at a temperature between +5°C and +35°C; the product must not be allowed to freeze.
