Substrate Quality / Pre-Treatment

Ensure surfaces are clean and free from contaminants before application:

Steel and iron: Must be clean and free of oil, grease, and rust
For optimal adhesion, create a roughened or “V” shape profile at the leak
Porous substrates should be pre-soaked before applying

Quickly combine powder and water in a container
Mix thoroughly and apply immediately with a gloved hand or trowel

Application Process

Firmly press the mixed mortar into the leaking area
Hold in place until it hardens

Colour accuracy disclaimer: We have taken care to display the most accurate visuals of our products. However, we are not responsible for the colour accuracy of the device you are viewing our swatches on. These variations arise due to different computer monitors and devices (make, model and technology, as well as resolution, contrast and brightness control settings) in much the same way a scan will differ from an original image and a colour photocopy. Furthermore, coatings can exhibit variation in perceived colour depending on gloss level and application method. If you require a very specific colour match, please make your selection via actual swatches and colour boards available at our showroom.
