Urethane Flooring and Wood Substrate Floor

By dciflooringUncategorized

Urethane based/moisture-cure adhesives offer the largest range of application and highest installation security but are usually more expensive than other adhesives. They can be applied under almost any circumstances and have hardly any restrictions on type of wood floor or sub floor.

ELAST-O-COAT

ELAST-O-COAT Waterproofing Membrane is a tough, high quality, 100% solids, 2 part elastomermodified, high build epoxy coating. It is applied on floors and molded up onto vertical areas, over curbs, etc. as a SEAMLESS ELASTOMERIC MEMBRANE. It can be applied to virtually any shape or contour by brush, paint roller, trowel or squeegee. ELAST-O-COAT is designed for use underneath epoxy flooring systems and as a base coat for vinyl chip seamless flooring to provide a vibration resilient cushion and to deaden sound. It can also be used as a traffic-bearing surface in light traffic areas and as a crack & joint filler. ELAST-O-COAT can be applied on properly prepared concrete, plywood, metal and quarry tile.

In new construction the slab should have cured at least 60 to 90 days before testing and installation. Take several readings with a concrete moisture meter, or perform a calcium-chloride test or a phenolphthalein test according to instructions. If necessary, use the recommended moisture barrier, such as 6-mil poly. A high pH level can also adversely affect the performance of an adhesive, so some manufacturers also
recommend performing an alkalinity test. Installing a floor over an uneven slab can cause the adhesive to adhere to some spots in the flooring and not others. This creates a common customer callback of hollow spots in the floor that make a popping sound when walked on. For glue-down installations, a flat slab has a tolerance of 3/16 of an inch over a 10-foot span or 1/8 of an inch over a 6-foot span. To even out a slab, high spots can be ground down, or low spots can be filled with an approved leveling compound. The sub-floor should be compatible with the adhesive and product you’re installing. Super-slick concrete slabs can interfere with the adhesive’s bonding ability, so the surface of the slab may need to be abraded. Other surfaces, such as lightweight concrete, may not be compatible with certain adhesives, so always double-check with the manufacturer before you install. For a glue-down installation, the plywood sub-floor should be at least 5/8 inch thick in 4-by-8-foot sheets. Always check with the adhesive and flooring manufacturers for sub-floor requirements.
