Rapid setting fiber reinforced hybrid floor leveling compound with Hybrid Active Dry Technology

SCHÖNOX HS 10 F combines the advantages of a low tension calciumsulphate based leveling compound with the fast drying of cementitious systems. Embedded fibres provide reinforcement, making it unnecessary to use a reinforcing mat. Especially suitable for wood floor boards, chipboards, OSB-boards, mastic asphalt screeds and other critical substrates. Because of the innovative Hybrid Active Dry Technology it is ready for covering already after 6 hours.

Technical Data

Applications

SCHÖNOX HS 10 F is suitable for filling, smoothing, evening and levelling of substrates:

• under textile and elastic coverings as well as parquet
• in combination with lamina panel heatings (warmwater or electrical), e.g. Uponor or Magnum in interior areas.

Substrates

SCHÖNOX HS 10 F is suitable for filling, smoothing, evening and levelling of:

• Wood planks
• OSB boards (class 3 - 4)
• Particle boards (P4 - P7)
• Fixed parquet
• Dry screeds
• Calcium sulphate based screeds
• Mastic asphalt screeds (sanded) IC 10 and IC 15 according to EN 13 813, layer thickness 3 to 10 mm
• Magnesia screeds
• Xylolite screeds
• Old substrates such as ceramic tiles, natural stones and terrazzo
• Old substrates with old water-resistant adhesive residues
• Concrete
• Cement and rapid cement screeds

Requirements of Substrate

• Adequate strength, load bearing capacity, dimensional stability and permanent dryness.
• Free of residues which reduce adhesion, e.g. dust, dirt, oil, fat and loose particles.
• Surface treatments or any "friable" areas of the subfloor must be mechanically removed and the subfloor repaired with SCHÖNOX levelling compounds as required.
• Old, loose and weak levelling layers should be removed mechanically.
• With subsequent installation of floor coverings, cement screeds are required to display a residual moisture reading of ≤ 2.0 CM-% (heating screeds ≤ 1.8 CM-%), calcium sulphate screeds should have a reading of ≤ 0.5 CM-% (heating screeds ≤ 0.3 CM-%).
• Layers of water-soluble adhesives, e.g. sulphite-waste-adhesives, are to be mechanically removed. Remaining adhesive residues should be primed with SCHÖNOX HP RAPID.
• Old water-resistant adhesives are to be mechanically removed as far as possible.
• Old floors, such as ceramic tiles are to be thoroughly cleaned and sanded.
• Rooms in buildings without a basement, are to be sealed against rising dampness in compliance with the standard.
• Timber floors must be stable, sound and requires a normal moisture content of wood. Let some space (joint approx. 10 mm) to the walls while levelling to ensure ventilation of the construction.
• Loose boards and planks must be firmly screwed down. Change damaged wooden planks.
• The requirements of the relevant valid standards, guidelines and data sheets apply.

Priming

Normal absorbent substrates such as:

• Cement screeds
• Rapid cement screeds
• Concrete

Prime with SCHÖNOX VD (1:3) or SCHÖNOX KH FIX.

Non-absorbent, smooth, sound substrates such as:

• Mastic asphalt screeds, insufficient sanded
• Ceramic tiles (throughly cleaned and abraded)
• Water-resistant adhesive residues (re- moved as far as possible)

Prime with SCHÖNOX SHP or SCHÖNOX VD (neat).

Calcium sulphate substrates such as:

• Calcium sulphate screeds
• Dry screeds

Prime with SCHÖNOX KH FIX or SCHÖNOX VD (1:1).

Magnesia screeds (not xylolite):

Prime with SCHÖNOX SHP.

Xylolite screeds

Contact our technical team (on 0113 2455450 (option 2) or send a message to [email protected]) or Sika Technical for advice.

Wooden substrates like e.g.:

• Stable laid wooden planks
• Chipboard or OSB
• Parquet

Protect against moisture with SCHÖNOX VD (neat)(drying time 2 hours).

For layer-thickness exceeding 10 mm on substrates sensitive to mois- ture (e.g. calcium sulphate screeds, wooden substrates etc.) SCHÖNOX recom- mend priming with a reaction resin based primer e.g. SCHÖNOX HP RAPID.

Mixing Ratio

For 25,0 kg SCHÖNOX HS 10 F - approx. 5,5 l water

Recommended Method of Working

• The ideal working temperature is 15 ° C floor temperature, 18°C air temperature, ≤ 65 % relative humidity.
• Using a clean receptacle, add SCHÖNOX HS 10 F to cold clean water to form a homogeneous mixture. Use of a mixer with 600 rpm is recommended. After letting it stand for approx. 3 minutes, mix again thoroughly. Then pour out the levelling compound and spread using a smoothing trowel.
• Due to the high fibre content, full containers should be mixed to guarantee even distribution of the fibres.
• In the case of higher layer-thickness, contact with vertical structures should be avoided by putting in an perimeter isolating strip.
• If a second layer of levelling compound is to be applied, the first levelling compound layer should be primed with SCHÖNOX VD (1:1) or SCHÖNOX KH FIX when dry. The maximum layer thickness may not be exceeded in case of two-layer application. The second layer may not exceed the layer thickness of the first.
• Possible joints in the subfloor, e.g. in wooden planks, should be closed previously with a sturdy material.
• Carry out preparatory work - such as filling joints, evening out hollows and unevenness - using the sturdy repair mortar SCHÖNOX RR.
• Protect curing SCHÖNOX HS 10 F levelling layers from high ambient temperatures, direct sunlight and draughts.
• If grinding of SCHÖNOX HS 10 F is necessary use a paper or net with grit-size ≥ 80.
• Contact to metal like water-bearing pipes must be avoided (e.g. sealing of pipe penetrations), because especially galvanised steel pipes have no sufficient corrosion protection.
• Clean tools in water immediately after use.
