Sikafloor® DecoDur Quartz UEF
Sikafloor® DecoDur Quartz UEF is a multi layer moisture control and decorative quartz floor system. The first layer creates a moisture vapor tolerant barrier between the concrete substrate and finished with Sikafloor® System that consists of a self-leveling, cementitious urethane slurry, which is either finished smooth or broadcast to rejection with Sikadur® aggregate. The second layer is decorative color quartz broadcast, sealed with a high performance epoxy, polyaspartic, or urethane finish. It is designed to provide excellent resistance to abrasion, impact, chemical attack and other physical abuse. Sikafloor® DecoDur Quartz UEF is broadcast with color quartz aggregate to increase surface texture, slip resistance and provide a decorative appearance. The system is typically installed @ 5/32 - 3/16'' (4.0 - 6.3 mm).
- Can be applied on green concrete, typically 7-10 days. Full 28 days cure time is not necessary.
- Can be applied over partially cured concrete substrates (> 4% mass (pbw –part by weight) as measured with Tramex® CME/CMExpert type concrete moisture meter surface moisture).
- Can be applied to concrete substrates where <100 % relative humidity is measured as per ASTM F2170.
- Substrate has tensile bond strength in excess of 218 psi (1.5 MPa). Substrate has tensile bond strength in excess of 218 psi (1.5 MPa).
- Resists a very wide range of organic and inorganic acids, alkalis, amines, salts and solvents. Consult Sika Technical Service for full details.
- Similar coefficient of thermal expansion to concrete allowing movement with the substrate through normal thermal cycling. It will perform and retain its physical characteristics through a wide temperature range from -40 °F (-40 °C) up to 248 °F (120 °C).
- Non-tainting, odorless.
- Behaves plastically under impact / deforms but will not crack or debond.
- High abrasion qualities result from its aggregate structure.
- Extra Expansion joints are not necessary; maintain and extend existing expansion joints up through the Sikafloor® DecoDur Quartz UEF Flooring System.
- Minimal maintenance costs, superior life cycle cost advantage versus tile.
- Meets the requirements of USDA for use in food plants.

SUBSTRATE PREPARATION
Concrete surfaces must be clean and sound. Remove all dust, dirt, existing paint films, efflorescence, exudates, laitance, form oils, hydraulic or fuel oils, brake fluid, grease, fungus, mildew, biological residues or any other contaminants which may prohibit a good bond.
Prepare the surface by any appropriate mechanical means, in order to achieve a profile equivalent to ICRI - CSP 3-6. The compressive strength of the concrete substrate should be at least 3,625 psi (25 MPa) at 28 days and a minimum of 218 psi (1.5 MPa) in tension at the time of application.
Repairs to cementitious substrates, filling of blowholes, leveling of irregularities, etc. should be carried out using an appropriate Sika profiling mortar. Contact Sika Technical Service for a recommendation.
Edge Terminations
All free edges of a Sika® Ucrete® floor, whether at the perimeter, along gutters or at drains, require extra anchorage to distribute mechanical and thermal stresses. This is best achieved by forming or cutting grooves in the concrete. Grooves should have a depth and width of 2 times thickness of the Sika® Ucrete® floor. Refer to the edge details provided at http://usa.sika.com.
If necessary, protect all free edges with mechanically attached metal strips. Do not featheredge, always turn into an anchoring groove.
Expansion Joints
Expansion joints should be provided in the substrates at the intersection of dissimilar materials. Isolate areas subject to thermal stresses, vibration movements, or around load-bearing columns and at vessel sealing rings. Refer to details provided at http://usa.sika.com.
