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.

• 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

• 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)
