StoneFix XP350 Self Levelling Smoothing Compound can be applied in thicknesses from 3-50mm in a single pour. It provides an economic means of levelling and renovating existing floors, prior to the installation of floor coverings such as ceramic tiles, natural stone, timber or carpet.
This product is suitable for use in homes, schools, office buildings, public buildings, sports halls, department stores and hospitals. StoneFix XP350 Self Leveling Smoothing Compound is protein/casein free and can be used in biologically sensitive areas. Suitable for use with underfloor heating installations and is not affected by heat from central heating pipes and radiant heat mats once the product is cured.
PLEASE NOTE 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%.
StoneFix XP350 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 XP350 and StoneFix Acrylic Primer. The slurry coat should be one part powder to one part liquid by volume. Apply thinly with a brush and allow to dry.
LAYING ON WOODEN FLOORS (INCLUDING TONGUE & GROOVE AND CHIPBOARD)
The timber should be stable and able to carry the weight of the leveling compound and the overlayment. Flooring must not move when stepped upon. Partitions must not flex when pressed by hand. If this is not the case, reinforce the floor with noggins between the joists and replace the boards. Brace unstable partitions.
The surface of the timber should be primed with StoneFix Acrylic Primer diluted 1:1 with clean water.
Each 25kg bag should be mixed with 4.25 litres of clean cool water. Slowly mix for 3-5 minutes using a suitable drill with whisk attachment. Once mixed, the material is immediately ready for use and has a workability time of approximately 20-30 minutes. 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.
