Use method

• The support must be prepared by mechanical scarification or hydro-scarification for a depth of not less than 8 mm. The scarification of the support is an absolutely necessary operation to ensure sufficient grip of the coating applied. In the case of localized patches or repairs, cut the contours at right angles with an angle grinder.
• The support must not have traces of oils, greases, detergents.
• The support must be in good condition, clean, course, without crumbling parts or dust (suction of all dust and debris with an adequately equipped vacuum system). Wash the surface with pressurized water. Saturate the support with water before applying and eliminate any excess water on the surface.
• Application temperature: 5°C to 35°C.
• We strongly recommend the use of a vertical axis mixer with planetary or double horizontal helical movement, for optimal performance of site operations.
• MIXING: The powder is mixed with potable water in the measure of 11% - 12%, referred to the total weight of the mortar (about 2.75 lt per 25 kg bag) creating a homogeneous mixture. Mixing time: approximately 4 minutes with high-efficiency mixer.
• In the case of large thicknesses (e.g.: manhole repairs) use compaction with a vibrating needle or tamp it down in a very intense way.
• Level the surface with a vibrating screed on the prepared templates.
• The surface must be protected after application by polyethylene sheets or anti-evaporation treatments. The latter should be sprayed on the freshly cast and restored surface (provide anti-evaporation treatments only if no other protective or aesthetic-protective applications are planned above: contact our technical service for advice on the most indicated surface protection methods and on the type of product that can be used as a curing compound).
In the case of thicknesses exceeding 20 mm, FLOOR TENAX must be laid out, supported and floated on a suitable sub-base only with appropriate measures to ensure the structural adhesion and anchoring to the support itself. The methods of anchorage suggested include: laying with a special epoxy resin for structural construction joints (SYNTECH RGS or SYNTECH PAVISHEER); or positioning a galvanized steel net with 5x5 cm mesh and 2 mm wire, which is spaced from the support plane of half the expected thickness of FLOOR TENAX and anchored to the same by "L"-shaped connectors fixed in holes resinated with SYNTECH PROFIX or fixed by nailing with "nail guns".
Provide a cover with wet TNT and waterproof sheet as soon as the surfaces are walkable.
