Characteristics

REPAR SM is a fine plaster, monocomponent, thixotropic, rheoplastic, composite , "multipurpose"; based on high-resistance cements, superpozzolanic fillers, hydrodispersed polymeric resins, plasticisers, stabilisers, and anticorrosives, antiallergic additives, selected aggregates, microfibres.

Consumption

Approximately 1.65 kg/m² of REPAR SM for each millimetre of thickness to be made.

Use fields

Repairs, finishing coats, protective and waterproofing coatings, planar regularisations, surface coatings, adhesives, etc., on concrete and masonry supports, even in cold weather.

Preparation of supports

Application surfaces should be clean, free of soiling, crumbling and non-adhering parts, dust, etc., conveniently saturated with water until they reach the condition "saturated with dry surface".

Use method

Pour about 2/3 of the mixing water into the mixer, add REPAR SM and the remaining water; continue to mix until a homogeneous lump-free mixture is obtained. The mixing water should be about 15-18% of the weight of the bag. After mixing is completed wait a few minutes before applying. It is recommended to prepare a limited quantity of mixture at a time, to avoid waste.

Smoothe the surfaces to be regularised by applying the product with a spatula, sponge float, etc.

Application methods

- Brick trowel

- Finishing trowel

- Spatula

Tool cleaning

- Water

Permitted supports

- Plasters

- Concrete

- Cement-based or lime-based mortars

- Prefabricated concrete

Warnings, precautions and Ecology

Do not apply in case of direct exposure to sunlight; cure the protection and the prolonged moist hardening of exposed surfaces.
