Application procedures

Preparation of the surfaces. The surfaces to be used should be healthy, rigid, clean, dust-free, and should have suitable dimensions. The surface should be totally free of any fat, rust, paraffin, and other substances deteriorating adhesive force, and should not have small splinters. Edges of cavities and cracks  20 mm depth and width should be cut upright. The V-shape cavities with sharp cut corners are not allowed.

Preparation of mixture. Pour the required amount of the product into clean mixing container, and add the required amount of water during 60 seconds. Put on protective gloves and mix within maximum 30 seconds. Do not add any chemical substances to the mixture.

Application. Enlarge the areas soaked with water to the width by 20 mm. Mix the product with required amount of water in your  hands. When the mixture is warmed up, quickly apply it to cracked areas and areas where the water soaks. Put hand over the treated place and wait for 60 seconds. Carefully remove the hand after the product starts to harden. In case of larger cavities this procedure can be repeated from the cavity’s edges towards its center. Immediately after application the extra product should be removed from the cavity edges.

The product can be used for the purpose of insulation in the joints between walls and floor. Enlarge the joints to the width and depth by 20 mm minimum. Remove any wire, lead, wooden, and other small particles from the enlarged areas. Fill the joints with the IzoKontakt 1 product in appropriate manner. To fasten the metal anchor bolts and/or fastening elements to concrete surface drill a hole larger than the size of anchoring element in concrete surface using mechanical tools. Then clean the hole inside.

Before application of the IzoKontakt 1 wet the holes with required amount of water. Then fill the holes with the IzoKontakt 1 product. Quickly put metal anchor bolts and/or fastening elements to their places moving them in vertical direction, then apply products has been moisture-retaining features.

Recommendations. In case the ambient temperature in the area of IzoKontakt  1 application is below +50C and above +320C, the required temperature should be provided. The treated surface should be kept wet for 15-minute period. For dry surfaces and surfaces with high water absorption ability this period should be 30 minutes. After hardening the product can be removed by mechanical means only.


Differs depending on dimensions of the water soaked areas.
