The construction method of Okotin waterproof patching tape:

First, clean the color steel roof, sunroom, and glass house with water, wait for it to dry fully, and you do not need to apply any material; just stick it directly.

Secondly, the cement roof must be cleaned thoroughly, achieving the effect of high-pressure washing with a car wash machine. If no tools are available, a wire brush can be used to polish the areas to be adhered to a shiny, dust-free state and then clean them with water. After that, allow the area to dry thoroughly.

Thirdly, evenly apply the special undercoat oil, especially for sand holes and cracks, ensure that the undercoat oil is fully filled (one bottle of undercoat oil is recommended to brush 15 meters long);

Fourthly, when the base oil is completely dry, press it firmly after pasting the waterproof tape (recommend using a 15 cm wide tape for the cracks), and wait for a while. After a period of time, the butyl waterproof tape and the cement base surface fully integrate. Before the full integration, the special base oil has the role of sealing the dust on the surface of the cement and preventing water seepage, which can maintain watertightness;

Fifth, apply waterproof tape. Do not try to peel it off to check if it is stuck. A smooth cement roof will quickly integrate, while a rough roof needs some time for the adhesive to fully penetrate. This is because the butyl rubber is not solidified and has the ability to automatically adhere and penetrate. After a while, the tape will fully integrate with the cement.
