DRYKOTEC 7700
18 Kg
Two-component waterproofing based on thermoplastic resin and cements with active loads incorporated with synthetic fibers (polypropylene), forming after curing a flexible layer that accompanies the workability of the structure. This system has the advantage of resisting positive pressure, in addition to being flexible and applied cold.
Suitable for: areas subject to constant structural movements such as swimming pools, reservoirs, elevator shafts, terraces, balconies, kitchens, service areas, bathrooms, water mirrors, washbasins, gourmet balconies, laundries and kegs.
Perform regularization with a minimum drop of 1% towards the water drainage points, prepared with cement mortar and medium sand 1: 4 trace, adding DRYKOFIX CHAPISCO adhesive emulsion in the mixing water for greater adhesion on the substrate.
It is worth mentioning that no type of water repellent should be placed in the regularization mortar. The mortar must be finished with a minimum thickness of 2 cm. The surface must be moistened with water before applying the product. In the event of percolation or spurts of water from the water table, buffering must be performed before applying DRYKOTEC 1100.
Before applying DRYKOTEC 1100 in swimming pools or in buried concrete tanks, perform a water load test for at least 72 hours to accommodate the structure, checking for possible cracks and cracks that may occur at full load.
Mix the DRYKOTEC 7700 for 5 minutes, components A and B until it forms a homogeneous paste. Mix the product manually every 15 minutes.
Apply with a soft broom or brush. Moisten the surface well and apply 3 to 4 coats of the mixture in crossed directions, allowing to dry at least 4 hours before the next coat.
In critical areas, such as reservoir bottoms and cold joints, drains and pipes, a 2 × 2 mm mesh polyester industrial screen must be incorporated after the first coat. When applied to an area exposed to the sun, it must be hydrated for 3 consecutive days.
In tanks, reservoirs and any other areas that will be in permanent contact with water, the surface of the product must be cleaned, washing with water and neutral soap and rinsing with plenty to remove all soap.
There should be no product accumulated in the corners / corners of the waterproofed area, this excess can cause cracks. The application must be transferred to eliminate the excess. We recommend the use of mechanical p
rotection mortar on the floor for application in water tanks, due to the cleaning services that will be performed in the future.
For laying the final coating, we recommend AC-III glue cement.
DRYKOTEC 7700 cannot be used in places with a pH below 6.
Wait 96 hours after applying the last coat before doing the tightness test.
