KAVASSU CUREX

For application on freshly cast concrete or newly exposed concrete surface after removal of frame work, to form a temporary membrane which will retain sufficient moisture for effective curing to take place. The membrane eventually breaks down and disintegrates after which the surface can be painted. It is used for concreting generally, but especially useful for large areas of concrete such as pavements, runways, bridge decks and industrial floors also for vertical or slopping surface as on chimneys, towers, silos, canal lining, columns and beams where water curing is difficult or unreliable.

Single  application   forms  moisture  barrier  for  whole  of  curing  period.  No other curing necessary eliminates using of water, Hessian or sand completely. Reliable no risk erratic or poor curing and ensures cement hydration efficiently.

Increase strength gives rise to about 12-15% higher strength than water-cured concrete. Ensures hard wearing surface minimizes risk of drying shrinkage, cracks & dusty surface.

Protection against a “burning” of the fresh concrete surface, which is exposed to strong solar radiation, further protects concrete surface against influence of aggressive atmospheric conditions.

Easy and safe application, non-toxic and non-inflammable. Eco-friendly.

Free cure is a membrane forming ready to use, white colour emulsion of specially blended synthetic waxes, complying with ASTM C 309-86.

Concrete is the most versatile construction material and is widely used in a variety of constructions. However, along with correct composition and preparation it is essential to carry out proper curing of concrete in order to realize its advantages. Common method of curing such as, continuously spraying water on concrete surface and ponding etc. are inconvenient and also expensive evaporation of water from concrete will deprive it of its much needed water for hydration resulting in capillary type pores, lower compressive strengths, chipping off on the surface,& development of surface cracks. Liquid membrane forming, concrete curing compound is based on the principle that concrete has enough water for uninterrupted hydration.

One full coat until a continuous, uniform film has been achieved.

Kavssu Curex should be applied following the final finishing operation & immediately after the disappearance of water seen from concrete surface. It is important not to apply Kavssu Curex when standing water is still present on concrete. If the concrete has already lost some of its surface water than it is recommended to fog down the surface before application of Kavssu Curex.

Low-pressure spray, roller equipment most preferred & generally used is a knapsack sprayer of the type commonly used in horticulture or pest control while spraying, the distance between the sprayer and the concrete surface should be approximately 1meter. Thus a uniform coating is guaranteed. It should be made sure that the spraying is properly carried out. Immediately after use the equipment should be cleaned out thoroughly with fresh water. Kavssu Curex has a shelf life of minimum  12 months when stored at ambient temperature. Container should be kept airtight to prevent surface evaporation. Prolonged exposure to direct heat or direct sunlight must also be avoided.
