DO NOT apply if subfloor temperature is below 5°C or above 25°C. All direct to earth subfloors must have either an effective integral damp proof membrane or alternatively a surface damp proof membrane applied.


Substrate must be hard, sound and free from dust, oil, grease, paint, plaster, laitance or any other contaminant that could prove a barrier to adhesion. Heavily contaminated floors may require special treatment and specific advice should be sought. Generally substrates are best prepared by mechanical methods such as shot blasting, planing or scabbling. The substrate must be vacuum cleaned prior to application of primer. The substrate must not leach moisture. Anhydrite screeds must not have a moisture content greater than 0.5% or 75% relative humidity (RH) is required. This can easily be tested with a hygrometer. Once the screed has dried it is essential that surface laitance is removed. This is achieved by scabbling, followed by vacuum cleaning to remove any dust. Recently laid cement / sand screeds must be fully cured before covering. Indoor air and floor slab temperature must exceed +5°C with relative humidity not exceeding 95%. Can be applied directly to adhesive residues if it is thin and firmly bonded to the substrate and is not susceptible to moisture.


Porous substrates must be primed with StoneFix Acrylic Primer. Non porous substrates such as ceramics, flooring grade asphalt and highly polished stone should be primed using a slurry coat of StoneFix XP220 2 Part using part (A) & (B). The slurry coat should be one part powder to one part liquid by volume. Apply thinly with a brush and allow to dry.


Materials are supplied in ready to use quantities of 25kg StoneFix XP220 2 Part (A) powder and 5 litres of StoneFix XP220 2 Part (B) liquid. Shake the liquid vigorously before pouring into a suitable mixing container. Add the powder gradually, stirring continually for approximately 2 minutes using a suitable drill with whisk attachment allow to stand for 2 minutes then re-mix. This process allows the polymer additives to dissolve and activate. Use the mixed compound immediately. If the mix stiffens before it has been spread, it must be discarded. Do not add extra water or liquid.


The mixed material is poured onto the prepared subfloor and spread with a smooth edge trowel to the required thickness in one operation. Alternatively the use of a spiked roller will ensure a smooth even finish that will not require any further attention prior to the floor coverings being applied.


For every 1mm thickness 1.7kg of dry powder per square metre will be required, i.e. 1m2 at 10mm thickness will require 17kg of dry powder.
