Shaw 4151 Universal Performance Adhesive

Shaw 4151 is an enhanced formulated universal performance adhesive designed for multiple backing systems, including resilient (sheet/lvt/lvp), carpet tile and non-patterned EPBL.

• For interior use only.
• Wood Association approved wood underlayment and subflooring. See Resilient Wood Substrate Information
• Sound and properly prepared concrete (on, above or below grade), metal, wood fiberglass and terrazzo.
• Existing resilient products should be over 1 year old, secure and fully adhered with a full spread of adhesive. Remove all waxes and polishes from the existing floor before installation.

• RH - 99% (ASTM F-2170), provided the site is absent of hydrostatic pressure.
• CaCl / MVER - 12 lbs (ASTM F-1869)
• pH - 12 (ASTM F-710)
• For on-grade / below grade installations, CaCl, RH and pH testing are required.
• For above grade installations, RH testing is required.

For older slabs or slabs with a prior history of moisture related issues, Shaw Technical Support recommends moisture mitigation in the form of a 2-part epoxy system, such as MoistureTEK.

For newer slabs with an intact moisture retarder, initial moisture levels should recede over time.

• Substrate must be structurally sound, clean, level and dry.
• Substrate must be free of dust, dirt, oil, grease, paint, curing agents, concrete sealers, adhesives, loosely bonded toppings, loose particles and any other substance or condition that may prevent or reduce adhesion.
• Do not use over substrates containing asbestos or active cutback adhesive.
• Fill depressions or cracks with a cementitious patching / leveling compound that meet or exceed Shaw Industries maximum moisture level and pH requirements. Use of gypsum-based patching and/or leveling compounds which contain Portland or high alumina cement and meet or exceed the compressive strength of 3,000 psi are acceptable.
• Installation site must be acclimated with HVAC in operation or the temperature must be controlled between 65-95 O F (18- 35 O C) and the ambient relative humidity controlled between 30-65% before, during and permanently after the installation.
• Do not use over chemically abated substrates.

Read and follow the product specific installation guidelines for layout, design and any special instructions for installation.

• Spread adhesive using the recommended trowel.
• Spread adhesive evenly over substrate, keeping the trowel at a 45° angle to the substrate.

After installation of floor covering, roll floor covering with a 75 – 100 lb roller.

NOTE: For vinyl, back roll the adhesive with a short nap roller to reduce telegraphing of adhesive ridges.

Note: Coverage rate, flash time and working time may vary based on temperature, humidity, substrate porosity, jobsite conditions and application practices. Coverages are estimates only. Actual jobsite coverages may vary according to substrate conditions, type of trowel used and setting practices. Trowel dimensions are depth/width/space. Areas with lower than normal relative humidity will result in a reduced working time.
