Everbuild 903 Bitumen Trowel Mastic 1 Litre - Black

Everbuild 903 Bitumen Trowel Mastic is suitable for use on mastic asphalt, roofing felt, corrugated iron, metal guttering, and downpipes.

Apply using a trowel. Ensure the surface is clean and dry before application. Smooth the mastic evenly.

It's best to apply the mastic to a dry surface for optimal adhesion. Try to remove any moisture or standing water.

The mastic forms a surface skin, but the material underneath remains soft, allowing for movement. Drying time can vary depending on temperature and humidity.

Store in a cool, dry place, away from direct sunlight.

It is not typically recommended to paint over bitumen mastic. The paint may not adhere properly.

The product's shelf life is typically 12 months from the date of manufacture when stored properly.

Ensure the mastic is at room temperature. If it is too thick, try warming it slightly (do not overheat).

Make sure the surface is clean and dry before applying. Use a primer if necessary.

Ensure adequate ventilation. The curing time can be affected by temperature and humidity.
