REPAR PLUG

Super-adhesive rendering for cement or minimally absorbing supports

Code: INT.0127

Components: 1

Appearance: Powder

Cement mortar by rendering, monocomponent, super-adhesive, based on binders with high resistance, selected aggregates, polymeric promoters of adhesion and specific agents. Specific for the preliminary treatment by "rendering" concrete surfaces, mixed masonry, rocky walls and other not very absorbing surfaces, for subsequent coating with traditional (INTOSANA), dehumidifying (SANATIGH) and/or thermo-insulating (SANAWARME or CALEOSANA) plasters.

Use fields

Gripping rendering for subsequent plasters, both based on cement and hydraulic lime; protective coatings, renovation of works and structures in reinforced concrete.

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 PLUG and the remaining water; continue to mix until a homogeneous lump-free mixture is obtained. The mixing water should be about 16-18% of the weight of the bag. After mixing is completed wait a few minutes before applying the product by "spraying" ("scratch coat" ), by brick trowel and plastering trowel or plastering machine. The scratch coat, applied by "spraying", must provide a corrugated surface to promote the grip of the plaster that must be applied promptly: within 2-3 days.

In the case of successive dehumidifying (SANATIGH) or insulating (SANAWARME or CALEOSANA) plasters, hold the sprayed surface, "open" (non-homogeneous over the entire surface).

Application methods

- Finishing trowel

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.
