The value-engineered, easy-to-use, self-leveling underlayment designed for use over various substrates including concrete and ceramic tile. It’s proprietary Low Alkali Cement (LAC) based formulation provides a protective, smooth and flat surface on which sensitive finished floor goods can be laid directly without additional preparation.

ACCEPTABLE SUBSTRATES / PERFORMANCE CHARACTERISTICS

DRYTEK® 4000 INSTALLATION INSTRUCTIONS:

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 vacuum. Cutback adhesive must be removed down to a thin residue by razor scraping or equivalent. Surface bond strength of substrate should be minimum 72 PSI (0.5 MPa). Surface should be primed with DRYTEK® 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 DRYTEK® 4000. Contraction joints, construction joints, and cracks in the substrate which may be subject to movement after installation of DRYTEK® 4000 must be maintained as joints in the new surface. For use over wood substrate reinforcement (Diamond Lath, Standard steel concrete reinforcement lath or similar) must be used. Felt-backed floor coverings must be removed prior to application of DRYTEK.

MIXING

DRYTEK® 4000 should be mixed with 4.0 to 4.5 quarts of water per 50 lb bag. Do not over water. For manual application, add product to water and mix for 2-3 min. with a heavy duty drill (650 rpm) to obtain a lump free mix. DRYTEK® 4000 can also be used in most pump equipment. Please consult with a DRTYEK 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 1/8” to 3” (3-76mm). Perform Drytek Flow Kit test and adjust water accordingly until ideal patty size of 10-11 inches is obtained. Immediately smooth the poured slurry with a smoother. After initial set of material, remove all overlap marks, seams, and inconsistencies by scraping with steel trowel. Material can be walked on after 3-4 hours

FLOORING INSTALLATION

Finished floor goods can be applied to surface 72 hours after application, depending on thickness, drying conditions and type of finished floor. Due to the relatively low pH level of DRYTEK 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 DRYTEK underlayments when RH level of substrate (i.e. concrete slab, etc) is 95% 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

Apply only over ceramic or quarry tile which is applied to a concrete substrate and well-bonded. Indoor applications only. Not for applications exposed to continuous water of intrusion. Must allow for eventual drying of substrates.

PACKAGING

DRYTEK® 4000 is available in 50 lb polyethylene-lined paper bags and in 2200 lb Bulk Sacks.

WARNING: Dust my 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.
