Pot Life: Sika® Primer AFP is designed for fast curing. Higher temperatures combined with higher air humidity will increase the speed of the curing process. Therefore, material in opened containers should be applied immediately. Once the container has been opened, the material will form a film after 1–2 hours approx. (+20°C / 50 % r.h.).

Application

• Apply Sika® Primer AFP using a 4”(100mm) roller.
• All surfaces must be clean, sound, dry and free from frost, dust, grease and oil. Paint, laitance and other poorly adhering particles must be removed.

Primer Application

Before applying Sika® Primer AFP, several conditions have to be met:

• Substrate temperature is between 5°C min. and 60°C max. and 3°C higher than the dew point temperature of the air in order to avoid the formation of condensation on the surfaces.
• Relative air humidity is between 5 % r.h. min. / 85 % r.h. max.
• Substrate moisture content is ≤4 % pbw.
• Ambient temperature is required to be between 5°C min. and 35°C max.

If these conditions are not met, Sika® Primer AFP can not be applied.

Drying

• SikaBond® -TF Plus can be applied, depending on the weather conditions, between 6-18 hours after Sika® Primer AFP was applied.
• The minimum drying time before applying SikaBond® -TF Plus is approximately 6 hours at 20°C.

Note: Times are approximate and will be affected by environmental conditions.

Storage Conditions

• The product must be stored properly in original, unopened and undamaged sealed packaging in dry conditions at temperatures between 0°C and 25°C.
• Higher storage temperatures may reduce shelf life of product.
• Reference shall also be made to the storage recommendations within the safety data sheet.
