Beware of condensation!
The substrate and uncured floor must be at least 3 °C above dew point to reduce the risk of condensation or blooming on the floor finish.
Note: Low temperatures and high humidity conditions increase the probability of blooming

Metal substrates

Quartz sand recommendation:

• When overlay is with liquid applied membranes, use medium broadcast ~0.8 kg/m²
• When overlay is with bitumen membranes, use full broadcast ~2 kg/m²

Note: These figures are theoretical and do not allow for any additional material required due to surface porosity, surface profile, variations in level or wastage etc.

Strictly follow installation procedures as defined in method statements, application manuals and working instructions which must always be adjusted to the actual site conditions.

Sikalastic®-10 Primer EP must be thoroughly mixed using a low speed electric stirrer (300 - 400 rpm) or other suitable equipment. For the preparation of mortars use a forced action mixer of rotating pan, paddle or trough type. Free fall mixers should not be used.

Cementitious substrates

• The concrete substrate must be sound and of sufficient compressive strength (minimum 25 N/mm²) with a minimum pull off strength of 1.5 N/mm².
• The substrate must be clean, dry and free of all contaminants such as dirt, oil, grease, coatings and surface treatments, etc.
• Concrete substrates must be prepared mechanically using abrasive blast cleaning or scarifying equipment to remove cement laitance and achieve an open textured surface.
• High spots must be removed by grinding.
• Weak concrete must be removed and surface defects such as blowholes and voids must be fully exposed.
• Repairs to the substrate, filling of blowholes/voids and surface levelling must be carried out using appropriate products from the Sikafloor®, Sikadur® and Sikagard® range of materials.
• All dust, loose and friable material must be completely removed from all surfaces before application of the product, preferably by brush and/or vacuum.

Metal substrates

• The substrate must be clean, dry and free of all contaminants such as dirt, oil, grease, coatings and surface treatments, etc.
• Any rust must be carefully removed by wire brushing or using Sika® Rustoff-100, followed by power washing.
• Any damaged metal must be repaired or replaced as suitable.

Primer

1. Prior to mixing, stir part A mechanically.
2. When all of part B has been added to part A, mix continuously for 3 minutes until a uniform mix has been achieved. Over mixing must be avoided to minimise air entrainment.

Levelling layer and Repair mortar

1. Prior to mixing, stir part A mechanically.
2. When all of part B has been added to part A, mix continuously for 3 minutes until a uniform mix has been achieved.
3. When parts A and B have been mixed, add the quartz sand and mix for a further 2 minutes until a uniform mix has been achieved.
4. To ensure thorough mixing pour materials into another container and mix again to achieve a consistent mix. During the final mixing stage, scrape down the sides and bottom of the mixing container with a flat or straight edge trowel at least once to ensure complete mixing. Over mixing must be avoided to minimise air entrainment.

Prior to application, confirm substrate moisture content, r.h. and dew point. If moisture content > 4 % pbw, Sikafloor® EpoCem® may be applied as a T.M.B. (temporary moisture barrier) system.

Primer

1. Pour mixed primer onto the prepared substrate and apply by brush, roller or squeegee then back roller in two directions at right angles to each other. Ensure a continuous, pore free coat covers the substrate. If necessary, apply two priming coats.
2. Immediately broadcast quartz sand on wet primer.
3. Remove excess sand after primer is cured.

Levelling layer or scratch coat

1. Pour the mixed scratch coat material onto the prepared substrate and apply by trowel or squeegee. Ensure a continuous, pore free coat covers the substrate. If necessary, apply two coats.
2. Immediately broadcast quartz sand on wet scratch coat.
3. Remove excess sand after scratch coat is cured.

Repair mortar

1. Apply the repair mortar screed evenly on the substrate, using levelling battens and spatula as necessary.
2. After a short waiting time compact and smoothen the mortar with a trowel.

Clean all tools and application equipment with Thinner C immediately after use. Hardened or cured material can only be mechanically removed.
