Perfect Concrete Finish

Nafuclar’s range of surface retarders enables the architect to design the surfaces and exteriors and interiors in various types. Nafuclar range of surface retarders for the production of exposed aggregates concrete finishes is manufactured by utilising the latest polymer technology of MC-Bauchemie Germany by MC-Bauchemie (India) Pvt Ltd. It is used for roughening the concrete surfaces, enabling keying of future plasters to obtain better bonding. Availability The range is available in several grades like W 32, W 16, W 08, W 04, for different sizes of aggregates and for different depths of etching. Nafuclar S is also available for providing sand faced effect on the surfaces. These properties of Nafuclar enable the architect to design the surfaces and exteriors and interiors in various types. Rounded and coloured aggregates can be incorporated in the mix to give several effects. Nafuclar is also an excellent aid which can be used by precast manufacturers of vases, flower beds, ashtrays, garden paving, kerb stones, etc. The use not only imparts the surfaces aesthetic view, but also avoids the dusting of surfaces as cement slurry does not come into contact with foot traffic, etc. Its usage Nafuclar in the normal face down process, should be applied to the form work and allowed to dry. Its mould release properties avoids the need for additional form oil. Also, a special grade of Nafuclar called Nafuclar P 20 is available for spraying on the wet surfaces. This enables exposed aggregate surfaces on both the sides for compound walls, partition walls, etc. The concrete, normal or with special aggregates can be cast in the normal fashion. After opening the form work the next day, the surfaces should simply be cleaned with water to obtain a flawless exposed aggregate surface with even depth of etching. By virtue of formulation, only the top cement skin is retarded and other aggregates are more firmly bound in the mass of concrete to avoid falling off of the aggregates.
