Products : Adhesives : Resilient Adhesive : Vinyl PSA Pressure Sensitive Adhesive

Vinyl PSA Pressure Sensitive Adhesive

Vinyl PSA is an advanced pressure sensitive adhesive designed for the challenges of today’s most popular resilient and soft surface flooring. Adding to its versatility, this unique formulation allows it to be used in permanent or releasable applications. Vinyl PSA is solvent and glycol free, making it ideal for projects that require low VOC’s. The high moisture and pH resistance make this product ideal for even the toughest applications.

Suitable as an adhesive

  • LVT-LVP / Luxury Vinyl Tiles and Planks
  • Carpet Tile (Vinyl and non-vinyl backed)
  • Vinyl sheet goods
  • Fiberglass sheet goods
  • VCT/Vinyl Composition Tiles

Conformance to Building Codes

Installation must comply with the requirements of all applicable local, state and federal code jurisdictions.

Environmental Consideration

Custom® Building Products is committed to environmental responsibility in both products produced and in manufacturing practices. Use of this product may contribute to LEED® certification.

Suitable Substrates

  • Concrete (industry approved)
  • Cement/epoxy terrazzo
  • Plywood and other approved wood substrates
  • Cement-based self-leveling underlayment and patching compounds
  • Properly prepared primed/sealed gypsum underlayment per ASTM F2419
  • Radiant heated floors (temperature should not exceed 85° F)
  • Existing well bonded floor coverings
  • Epoxy Coatings / Mitigation systems

* All surfaces / substrates above require proper surface preparation

Acceptable Substrate Conditions

  • RH – 95 % / ASTM F2170 Relative Humidity in Concrete Floor Slabs – situ Probes
  • MVER – up to 12 lbs. / ASTM F1869 Moisture Vapor Emission Rate
  • pH [Substrate] – up to 12

* Contact Technical Services for test results/readings outside above conditions.

General Surface Prep

All surfaces must be structurally sound, clean, dry and free from contaminants that would prevent or inhibit adhesion bonding. Concrete and cement-based underlayment/patching compounds must be fully cured and not exhibit signs of moisture or hydrostatic conditions/issues. Any existing adhesive must be removed to an embedded residue. All surfaces must be level, even, flat and smooth. Self-leveling underlayment Concrete as well as cement-based underlayments and patches must be fully cured and free of any hydrostatic and/or moisture problems.

CUSTOM® products may be used in assemblies over concrete with high moisture vapor emission levels provided that other materials such as finish flooring, adhesives or membranes are approved in these conditions. Consult the manufacturers for their limitations and requirements. Additionally, any sources of moisture are to be limited to initial concrete placement and not from sources such as water intrusion or from a lack of an effective vapor retarder/barrier. Substrate must be prepared per ASTM F710 standards.

It is the responsibility of the installer to determine the suitability of the substrate and any required preparation work necessary to ensure a successful installation.

Assembly mockups will determine suitability for these conditions on specific projects. Contact CUSTOM Technical Services for product information (800) 282-8786.

Fill all surface cracks, grooves, depressions, control joints and non-moving joints According to ASTM F710.

Contaminants or curing compounds should be mechanically removed before installation. Concrete must be free of efflorescence and not subject to moisture beyond the floor covering manufacturers' limits or hydrostatic pressure. Lightweight concrete surfaces must have a tensile strength in excess of 200 psi (1.4 n/mm²). HVAC must be operational between 60-95°F/30-65% relative humidity a minimum of 72 hours prior to installation enabling the substrate, adhesive and flooring to be properly climatized – See flooring manufacture’s requirements.

Disable radiant system 24 hours prior, during and after installation – Follow radiant system manufacture’s instruction for start-up procedures.

Limitations to the Product

IMPORTANT NOTE: Finished Flooring limitations and requirements will supersede recommendations of Vinyl PSA adhesive. Consult flooring manufacturer for performance data and recommendations.

  • For interior use only. Do not use when ambient and/or substrate temperature is below 50° F (10° C) or above 95° F (35° C) or when condensation exists.
  • Do not install into/over standing water (existing substrates and/or new concrete).
  • Existing adhesive must be removed to an embedded residue with no surface trowel ridges.
  • Do not install over treated plywood.
  • Concrete pH not to exceed 12, consult flooring manufacture for limitations.
  • Do not install when MVER exceeds 12 lbs. per ASTM F1869.
  • Do not install when RH/Relative Humidity exceeds 95% per ASTM F2170.

*Not for use as a moisture mitigation system [see CustomTECH™ MVC]

Cleaning of equipment

Clean with water before adhesive dries. Dried adhesive can be cleaned with mineral spirits.

Product Maintenance

Allow seven days after installation before cleaning flooring with saturated water and liquid compounds. General Contractor, Flooring Contractor and Building owner must provide proper climate controls per flooring manufacturers requirements before, during and after flooring installation.

Properly installed product requires no special maintenance, see flooring manufacture for service and maintenance requirements.
