DRYTEKT 760

DRYTEKT 760 fiber reinforced is a premium quality, cement-based self-leveling underlayment. Its fast-drying formulation is designed for use over a wide range of substrates, including concrete, pvc, vct, wood, ceramic and quarry tile. This unique formulation contains special fibers which provide added reinforcement. Also recommended for use with radiant heating systems.

PERFORMANCE CHARACTERISTICS

TECHNICAL INFORMATION

PREPARATION OF SUBSTRATE
Substrate shall be free from dust, oil or any contaminants which may contribute to decreased bond. Weak surfaces must be mechanically cleaned to sound and solid substrates by shot-blasting, scarifying or similar. Remove any loose particles such as adhesive residues and then vacuum. Surface bond strength of substrate should be minimum 72 PSI (0.5 MPa). Surface should be primed with DRYTEKT Primer. Substrate temperature should be a minimum 43°F (6°C) during application and air temperature maintained between 50-77°F (10-25°C). Adequate ventilation should be provided to ensure uniform drying. Moisture content of substrate should be RH 95% or less prior to application of DRYTEKT 760. Reinforcement ( Diamond Lath, Standard steel concrete reinforcement lath or similar ) should be used over substrates with high deflection or movement. Felt-backed floor coverings should be removed prior to application of Drytek.

MIXING
DRYTEKT 760 should be mixed with 4.5 to 5 quarts (4-4.5 L) of water per 55 lb.bag. Do not over water. For manual application, add product to water and mix for 2-3 minutes with a heavy duty drill (650 rpm) to obtain a lump-free mix. DRYTEKT 760 can also be used in most pump equipment, please consult with Drytek representative to verify equipment compatibility. A slump test should always be performed to ensure that mix is homogenized and free from separation.

APPLICATION
Pour blended material onto substrate at a thickness of between 1/8"- 2" (2-50 mm) for all surfaces except lightweight concrete, where a thickness of 1/4"- 3/4" (6-20 mm) must be maintained or wooden substrates where a minimum thickness of 3/4" must be maintained, where no reinforcement mesh or lath will be used. If using reinforcement mesh or lath over wood, a minimum 3/8" pour depth shall be maintained. Perform slump test and adjust water accordingly until ideal patty size of 10-11 inches is obtained. DRYTEKT 760 has a liquid merger time of 3-5 minutes at 68°F (20°C). Immediately smooth the poured slurry with a notched trowel or smoother. After intitial set of material (approx. 20-30 min.) remove all overlap marks, seams and inconsistencies by scraping with steel trowel. Material can be walked on after 1-2 hours.

FLOORING INSTALLATION
Finished floor goods can be applied to surface 6 hours after application, depending on thickness, drying conditions and type of finished floor. Due to the relatively low pH level of DRYTEKT floor leveling products, finished floor goods can be applied rapidly without risk of adhesive bond failure. As a general rule, permeable materials such as carpeting may be adhesively or mechanically applied to DRYTEKT underlayments when RH level of substrate (i.e. concrete slab ,etc) is 95% or below. Non-permeable items such as pvc can be applied at RH levels of 85% or below. RH levels should be determined according to ASTM standard F2170. Always test performance suitability and compatibility of finished floor systems prior to their application. Sample surfaces should be installed as a field test so as to be representative of entire surface and tested for intended use. Always refer to finished floor manufacturers recommendations regarding installation instructions, restrictions and compatibility.

LIMITATIONS
For indoor applications only. Not for applications exposed to continious water of intrusion. Must allow for eventual drying of substrate.

PACKAGING

WARNING: Dust may cause skin, eye, nose, throat, or respiratory irritation. Avoid dust inhalation and exposure to dust. If dusty, wear a NIOSH/MSHA-approved dust respirator. Use proper ventilation to reduce dust exposure. Portland cement is strongly alkaline and can be corrosive to eyes, skin and respiratory tract. Wear eye and skin protection. If eye contact occurs, immediately flush thoroughly with water for 15 minutes and get medical attention. Do not ingest. If ingested and any discomfort occurs, call physician.
