PROPERTIES



Fiber reinforced, brushable cementitious mortar that protects, from water absorption, light weight fill materials to be covered with cement screeds. The protection is essential when those surfaces crack or they are unstable and dusting.
Penetration points, like cracked grout joints around tiles and marble, will soak lightweight fill materials, storing water within them.
A frequent occurence, resulting in the oxidization of the concrete steel reinforcement (rebars). The penetrating water gradually oxidizes them, and equally disintegrates the plaster and paint on the surfaces underneath resulting in bursting and peeling. Classified as a protective for concrete surfaces (c) per EN 1504-2.

APPLICATION



HYDROSTOP FLOOR is absolutely necessary before installing tiles and marble, to waterproof substrates in swimming pools, bathrooms and showers, balconies, as well as terraces and aircrete.
Necessary for surface protection from moisture and  their smoothing out.
Surfaces with hairline cracks, exposed to intense temperature variations, as well as any intersecting points of vertical with horizontal surfaces to be covered with skirting boards, require flexible sealing.
The addition of DUROSTICK D-20, acrylic emulsion in the mixing water, at a ratio of 1 part D- 20 to 1 to 2 parts water or 1 part DUROMAX to 5 parts water, will increase the flexibility of the product, its surface  resistance to abrasion, its adhesion, and will also increase its waterproofing properties.
It is highly recommended to tile after at least two days.

USE

1. Surface preparation
Clean all surfaces from dust, oil, grease, loose debris, and necessarily rinse with water thoroughly. Empty the mortar into a clean container with cool water, at a ratio of 7-7.5lt of water to 25kg of powder, and mix with a low speed electric mixer or a cement mixer, until a lump free, homogenous mass is created.

2. Application
Apply HYDROSTOP FLOOR, on soaked surfaces, in 2-3 crosswise layers of equal thickness, 1mm each, with 3-4 hours between coats. Use an emulsion brush (pic.2), roller (pic.3), or a floor squeegee or even the flat side of a notched trowel (pic.1) used for tile installations, to apply the product.
If the time between coats is more than 3-4 hours, then soak the surface again.

NOTE


• The product, after hardening, is harmless to health.
•The newly coated surface must be protected from rain or frost for the next 24 hours, after completion of each coat.
