The Basics
Apply Tack Coat
Apply a tack coat to your surface using a trowel—1kg covers approximately 1.6m². Create texture with a serrated squeegee to help aggregate adhere.
Mix VubaRend
Mix 1kg of VubaRend with 10kg of aggregates (either 1-5mm blend or 1-3mm). Mix until all aggregates are evenly coated.
Apply the Mix
Apply from the base of the wall upwards using very firm pressure at 6-10mm depth. Smooth the surface until satisfied with the finish.
Mixing Ratios
3-6mm Aggregate
800g to 900g VubaRend mixed with 10kg aggregate
Mixed 1-6mm Aggregate
900g to 950g VubaRend mixed with 10kg aggregate
1-3mm Aggregate
950g to 1,000g VubaRend mixed with 10kg aggregate
Surface Preparation
Porous Surfaces
Apply an initial thin tack coat first, allow to soak in, then apply tack coat over the top as normal.
Smooth Surfaces
Apply Vubaprime EP-TC, broadcast with Vuba Grip Quartz at 65% coverage, cure overnight, then apply tack coat to the profiled surface.
⚠️ Important Notes
VubaRend is moisture-curing and more intolerant to moisture than normal binders. Do not apply in wet conditions. Do not use soapy water to clean the trowel - use Vuba Trowel Cleaner instead.
