Watco Sand Additive is a dry silica additive for use with Roofite where a thicker repair consistency is needed. Mixing it into the compatible Roofite coating produces a trowellable compound for suitable larger cracks and local depressions.

It supports the Roofite repair system rather than acting as a separate coating. Use it where the manufacturer's instructions call for additional body, such as cracks wider than 3mm. For a ready-made repair compound, Watco Roofite Repair Mortar is a separate product with its own application and coverage guidance.

  • Dry silica additive supplied separately.
  • Increases the body of compatible Roofite.
  • Helps create a trowellable repair mix.

Surface Preparation

Prepare the roof and repair according to the Roofite system instructions. The surface must be sound and free of loose material and contamination. The range sheet calls for priming deep pits and cracks with Roofite before placing the Roofite and additive mortar.

Technical Data

Pack size 5kg
Material Dry silica sand additive
Intended use With Roofite for thicker repair applications
Application area Exterior roof repair system

Coverage

There is no single standalone spread rate. Material consumption depends on the Roofite mix and the dimensions of the repair. Follow the manufacturer's system guidance for the amount of additive rather than applying a coating coverage figure to the dry sand.

Directions for Use

  1. Prepare and prime the defect as specified for the Roofite repair.
  2. Mix the additive with the compatible Roofite material to the manufacturer's specified repair consistency.
  3. Trowel the prepared mixture into the primed defect, following the system detail.
  4. Allow the complete Roofite repair to dry before further treatment or access.

Limitations

This additive is not a waterproof coating by itself. Do not use it to alter unrelated coatings without manufacturer approval, and do not assume that a stronger or drier mix will improve the repair. Follow the Roofite instructions and additive safety sheet, including controls for handling dry material.

Product FAQs

What does the additive do?
It gives compatible Roofite more body so it can form a trowellable repair compound.

Is it for larger cracks?
The product page specifies mixing with Roofite for cracks greater than 3mm, following the complete repair system.

Can I use the sand on its own?
No. It is an additive for a specified Roofite repair mix, not a standalone waterproofing product.

Does it have a fixed coverage rate?
No. Consumption depends on the mix and repair dimensions; use the manufacturer's system guidance.
