The consumption of Sikalastic® P 691 is between 0.05 and 0.1 kg/m² depending on the condition and porosity of the substrate. The above consumption figures are intended as a guide only and may be higher on very rough or porous substrates.

The surface to which Sikalastic® P 691 is to be applied must be clean and dry and free from oil and grease and any other substance which may impair The temperature of the substrate must be at least 3K above the dew point.

Sikalastic® P 691 is a single component material. Prior to application, it should be conditioned to a temperature of 15°C to 25°C. Pour the amount required from the original container and apply by spreading with a squeegee followed by back rolling. It is important to apply Sikalastic® P 691 thinly and to avoid ponding. The curing time of the material is influenced by the humidity and the ambient and substrate temperatures. At low humidity and low temperatures, the chemical reaction is slowed down; this lengthens the curing time and the recoating intervals. At high humidity and high temperatures the chemical reaction is accelerated thus the time frames mentioned above are shortened accordingly. If the maximum re-coating times are exceeded, Sikalastic® P 691 should be re-applied. Following application, the material should be protected from direct contact with water which will impair adhesion to the subsequent coat. Ensure that the solvent contained in the material is allowed to flash off completely before applying the subsequent coat. The temperature of the substrate must be at least 3K above the dew point both during the application and for at least 4 hours after the application (at 15°C).

Re-useable tools should be cleaned carefully with a suitable thinner (Xylene / MEK / Acetone).
