PALACE FAST-FLEX is a polymer-modified, cement-based, protein-free, sub-floor smoothing underlayment, giving a consistently level screed up to 30mm thick.

PALACE FAST-FLEX incorporates specially blended cements, graded sands, built-in polymer, anti-shrink agents and organic super-plasticisers, which when mixed with water give the ideal properties for application over a comprehensive range of floor surfaces such as tamped or worn concrete and sand/cement floor screeds, plywood and dense impermeable surfaces. It is also suitable for heated sub-floors.

PALACE FAST-FLEX will give improved adhesion to all types of substrate and provide enhanced abrasion and point-load resistance. This product is not suitable for external application.

The receiving floor surface must be hard, sound and free from grease, dust, floor polish, laitance and loose deleterious materials such as worn surface coatings & plaster. Any adhesive & coatings residues must first be tested to determine if they are “moisture sensitive” and then removed if necessary. Prior to laying PALACE FAST-FLEX, the base concrete or sand/cement screed should be tested to confirm that it has had sufficient time to dry out to reach a consistent moisture reading of <75% R.H. (< 3.0% residual moisture content) - tested as per BS 8203:2017 - Annex B. Where it is not known whether an effective structural DPM is in place, or where the moisture test results show values in excess of 75% R.H (or > 3.0% residual moisture content), then a liquid damp-proof membrane such as moisture suppressant PALACE 1-COAT DPM should be applied onto the prepared concrete sub-base, before it is over-laid with. PALACE FAST-FLEX Although PALACE FAST FLEX will bond readily to most solid sub-floors, the application of a primer on highly porous surfaces will assist with maximising flow time & adhesion strength. PALACE MULTI-PRIME diluted 1 part to 3 parts water which can be used for this purpose. Highly porous substrates may need a pre-coat of primer at 3 parts water mixed with 1-part primer (allowed to completely dry) and then a second coat diluted 1 part water to 1 part primer before applying the levelling underlayment. Note: on very absorbent substrates a third coat may be required diluted 1-part water to 1-part primer. Anhydrite Screed (Calcium Sulphate) based floors are being over-laid, the application of two coats of PALACE MULTI-PRIME will be necessary to form a barrier & avoid any adverse interaction between the cement-based PALACE FAST-FLEX and the gypsumbased anhydrite screed beneath it.
