Repair Mastic & Waterproofing

If you’ve got a roof that needs repairing, whether it is leaking or there is some damage to the roof surface, Using repair mastic and waterproofing products may be just what you need. 

Repair mastic

Trowel mastic, or repair mastic, is the term typically used to describe a bituminous mastic that can be used to fill any joints, cracks, splits or damage within roofing materials, as well as general building materials. Trowel mastic can be used on a wide range of roofing materials, including roofing felt, asphalt, concrete, cement and metal gutters and downpipes, and applying mastic is incredibly effective because it is resistant to water penetration as soon as it is applied. The exact method of how to apply trowel mastic varies between roofing materials, so it is important to read the application method clearly, but trowel mastic is typically applied by a steel trowel or putty knife.


Waterproofing coatings are manufactured with the main aim of preventing water from penetrating through the roof surface and into the space below. Choose from general all weather roofing compounds, or opt for specific waterproofing products that can be mixed into a render, screed or mortar.
