Definitions
ImperviousCharacterisitc of a subfloor which porosity is very low. Adhesion on such substrates is usually more difficult and requires more attention and preparation.
PrimerLiquid or paste applied onto a substrate to obtain optimum bonding. It helps regulate the porosity of the substrate (reduce absorption, therefore adhesive usage), increase adhesion to non porous surfaces, improves application properties of later on applied adhesive

Working timeTime between end of waiting time and moment when the application is no longer possible

Uses

ROXOL S standard self-levelling compound is suitable for smoothing and levelling of screeds, concrete floors and other hard, rigid bases, up to a maximum thickness of 5 mm in a single work step.

ROXOL S is suitable for normal wear (plastic and textile coverings) in domestic/residential and light commercial locations.

For heavy-duty areas/locations with high point loading, it can be used only with Adjuvant Force 3 additive up to 10 mm thickness ; it is then suitable for heavy duty floor coverings including parquet floors and tiles.

Not to be used as a wearing surface.
For interior use only.

Benefits

Self-levelling
From feather edge to 10 mm
Easy to prepare
Does not shrink, very tolerant in renovation works
No primer needed on normally absorbent surfaces
Pumpable
Suitable for underfloor heating

Safety:

IMPORTANT: before embarking on any work involving ROXOL S the separate Product Safety Data Sheet must be studied carefully by those carrying out the work. Do not breath dust, PREVENT skin and eye contact with powder and particularly the wet material when mixed. Strong alkali when wet – can cause serious eye damage and may cause an allergic reaction resulting in skin disorders.

Shelf life:

Can be stored up to 9 months in dry conditions.

Application

PREPARATION

New construction: mechanically sanded screeds, incorporated cement screeds, concrete slabs, prefabricated concrete floors and asphalt screeds.

Renovation: existing tiling, terracotta, certain glue layers, asphalt screeds, plasterboard, rigid plastic tiles, semi-flexible and vinyl-asbestos tiling.

Preparation should be in accordance with building standards. Subfloors must be sound, of adequate tensile and compressive strength; free from laitance, cracks and structural defects; clean and free from dust, grease, curing compounds, sealers or any other contaminants that would inhibit proper bond.

Substrate residual moisture content must be less than 3%.

For anhydrite slabs, moisture content should be less than 1% for laying textile coverings and ceramic tiles, 0.5% for laying plastic coverings and parquet floors.

Underfloor heating

Underfloor heating systems must comply with current building regulations. In all cases drying time must be respected. Turn off the heating 48 hours before starting the work. The heating should be brought up to its operating temperatures gradually, in stages over 48 hours after laying the floor covering.

The following substrates must be pre-treated with suitable Bostik primers and bonding agents:

Substrates	Recommended Primer	Consumption	Remarks
Absorbent concrete and cement screeds	Unidur 10 1:3 water-diluted	100 g per sqm/layer	Water based primer
Normally absorbent concrete and cement screeds	Unidur 10 1:3 water-diluted or Unidur N 1:1 water-diluted	100 g per sqm	Water based primer
Impervious concrete and cement screeds, tiles, terrazzo and other similar dense surfaces, existing semi-flexible tiles	Unidur N (pure)	100 g to 150 g per sqm	Water based primer
Particle boards, plywood all qualities included waterproof or fireproof, plasterboards, bituminous adhesive residues, magnesite screeds, mastic asphalt screeds	Impreglue	100 g per sqm	Solvent based product - Flammable
Wooden floors, particle boards, plywood all qualities included waterproof or fireproof, plasterboards, adhesive residues ( bituminous, acrylic, alcohol based ), old floor paints, old industrial flooring (epoxy or PU), mastic asphalt screeds, existing semi-flexible tiles.	Primepox	100 g to 150 g per sqm	Water-based epoxy primer 2 components
Wooden floor, particle boards, plywood with gap filling	Primabois	350 to 600 g per sqm	Water-based cementitious primer
Metal decking	Eponal 376	200 g to 250 g per sqm	Epoxy damp proof primer- 2 components
Concrete, cement screeds, old ceramic tiles with humidity above 3% or with negative pressure from the basement	Eponal 376	400 g to 800 g per sqm	Epoxy damp proof primer- 2 components

PRECAUTION: Before using primer read the primer data sheet carefully and respect our recommendations for ground preparation.

Before proceeding with the subsequent application of the compound, always allow primers to dry in accordance with the technical information. Always allow at least 24 hours drying time for anhydrite screeds.

MANUAL APPLICATION

Pour approx. 6 litres of clean water (water temperature +8°C to +20°C) into a clean mixing bucket. Stir the compound powder into water with an electric drill and mixing paddle (<500 rpm) to obtain a lump-free mixture.

After mixing, a maturing time of at least 1 minute is recommended to optimise flow. Stir again for 30 seconds.

The smoothing and levelling compound must be applied to the substrate within the specified working time and smoothed with a trowel.

Hint: For thicker layers, using a spiked roller will help air evacuation and improve surface finish.

Any subsequent application of Roxol S is best performed as soon as the first layer is set for walking but still damp. If it is dry, an intermediate primer coat of water-based primer UNIDUR N (diluted) or UNIDUR 10 is required.

REMARK

Heavy duty area product preparation

Pour approx. 5 litres of water in a clean mixing bucket, add 1 kg of ADJUVANT FORCE 3, mix them prior to addition of compound powder and stir with mixer. Other steps are similar to the above description.

MECHANICAL PREPARATION (PUMPABLE)

ROXOL S can be mixed using a continuous "mixing-pump". In this case the optimum water content is regulated on the basis of product viscosity. This one must be equal to the viscosity obtained by standard mixing of 1 bag in 6 litres of water. (See the technical guidance / procedure relative to the technical system for preparing interior floors for the application of thin floor coverings).

Once mixed, ROXOL S is pumped and applied to the desired thickness (10 mm maximum with additive in one single continuous coat).

Protect from excessively rapid drying, e.g. due to direct sunlight, draught or high room temperature. Conversely, poor airflow and low temperatures will significantly increase drying times. Do not lay floor coverings until the compound is completely dry.

CLEANING
Tools may be cleaned with water whilst the mix is still wet.
