Floor Preparation
This guide intends to serve only as an outline for the most common floor preparation required.
Please contact us for any additional advice.
Concrete Subfloor Preparation
The concrete must be completely cured (this can take up to 8 weeks)
The floor surface must be smooth, unpainted and free of dust, oil, grease, tar and glue residues
Clean and sweep or vacuum floor surface
Timber Subfloor Preparation
The floor should be rigid and free from movement
Install a fibre cement underlay or insulation board over the timber structural floor before tiling
The floor surface must be smooth, unpainted and free of dust, oil, grease, tar and glue residues
Clean and sweep or vacuum floor surface
After the heating is placed, Coldbuster recommends laying a 10-15mm sand cement or liquid
leveller over the heater so there is a medium between the heating element and the flooring
Prepping Subfloor Surface with a Bonding Liquid (If heater(s) don’t stick due to dusty floor surface)
1. Apply a coat of bonding liquid mixed 1:4 with water using a paint roller & tray (avoid ponding),
2. Allow bonding liquid to dry completely before installing heater(s)
