REPAR PLUG

Super-adhesive rendering for cement or minimally absorbing supports

Code: INT.0127

Components: 1

Appearance: Powder

A single-component, super-adhesive cementitious mortar for rough coating, with a base of high-strength binders, selected aggregates, adhesion-promoting polymers and specific agents. Ideal for the preliminary “rough coat” treatment of concrete surfaces, mixed masonry, rock walls and other poorly-absorbent surfaces, for subsequent coating with traditional (INTOSANA), dehumidifying (SANATIGH) and/or thermal-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).

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.
