How can you remove contamination and laitance?

Following British Standard 8204 all subfloors/substrates must be free from contaminants that may prevent adhesion such as dust, oils, grease, surface laitance, water soluble adhesive residues and weak smoothing underlayments etc.

Various methods and machines exist which are designed for the preparation, removal and finishing of subfloors/substrates prior to the application of any UltraFloor product. They include STGs, Shotblasters, Planers, Grinders, Multi-strippers and Dust Extractors.

We recommend that you contact The Preparation Group for advice on the appropriate method for your job and hire details www.ppcgroup.co.uk.

Smooth dense surfaces can be roughened by mechanical scabbling to enhance the key.
