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


Approximately 2.0 kg/m² of REPAR SM BIC for each millimetre of thickness to be made.

Use fields

Repairs, finishing coats, protective coatings and waterproofing, regularisations planar surface coatings, adhesives etc., on concrete supports, masonry, plaster walls, floors and other surfaces even at low absorption (wall plastic coatings), and in mountain, marine, urban and industrial environments.

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

Mix the concrete powder (component A) with the polymeric hydrating dispersion (component B), preferably with a mixer at a low number of revolutions, gradually pour the powder into the liquid (in case of manual mixing add the liquid to the powder); continue to mix until a homogeneous lump-free mixture is obtained. The optimal consistency of the product and the consequent physical-mechanical performances declared in this technical data sheet can be reached using 4.5 kg of COMPONENT B for each 25 kg bag. The excess quantity of COMPONENT B (0.5 kg) is particularly useful for priming the substrate, or for wetting the trowel in the final smoothing operation, or in hot and arid environmental conditions where the mixed product is kept at rest in the bucket it may require some light addition of liquid to regain its optimal consistency, thus avoiding uncontrolled water additions.

Application methods

- Brick trowel

- Finishing trowel

- Spatula

Tool cleaning

- Water

Permitted supports

- Acrylic wall coatings

- Cement-based or lime-based mortars

- Concrete

- Plasters

- 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.
