Product Features

Armstrong S-995 adhesive is a premium high-strength adhesive for installing commercial sheet and dimensionally stable commercial vinyl tiles and vinyl plank over porous and non-porous substrates. Armstrong S-995 is a solvent-free, acrylic adhesive suggested for use in demanding commercial installations. When used to install commercial sheet, seams can be heat welded after two hours and can be used under hospital beds. The low odor is ideal for occupied buildings. 

IMPORTANT: Proper substrate preparations is essential. Moisture and pH testing must be performed and documented before installation begins. 

USAGE: Follow Armstrong Flooring’s installation instructions and proper adhesive application rate. All substrate preparation and testing procedures must conform to appropriate ASTM F710 guidelines and comply with Armstrong Flooring’s specification. 

NOTE: It is up to the end user to determine the coverage that is appropriate for flooring type and jobsite conditions. A Bond test prior to the installation will help identify the appropriate application rate, open and working time, and any potential bonding problems to the substrate or flooring. Follow Armstrong Flooring’s installation instructions and guidelines regarding adhesive application rate and methods.  

SUBSTRATES: Substrates must be clean and dry, free of dust, dirt, paint, wax, existing adhesives, or other contaminants including curing compounds that may interfere with the adhesive bond. Do not use on chemically cleaned substrates. Asphalt-based or cutback adhesive stains must be removed completely. 

POROUS SUBSTRATES: Commercial sheet flooring may be placed into adhesive after 10–20 minutes open time (flash off). Roll the installation in both directions with a 100 lbs roller immediately after flooring is placed and positioned.  

When installing vinyl plank and tile over porous or non-porous substrates, the adhesive should be allowed to dry to the touch to prevent slippage. Loss of adhesion can result if the flooring is not installed within the 2-hour working time of the adhesive. Roll the installation in both directions with a 100 lbs roller immediately after the installation is complete.  

NON-POROUS SUBSTRATES: Install vinyl sheet, tiles, and plank flooring into adhesive as it becomes dry to the touch with little or no transfer to finger. This will normally require 30–45 minutes of drying time at suggested installation temperature and humidity. To achieve a satisfactory bond when installing sheet goods over a non-porous substrate, the working time should be limited to no more than 60 minutes after the adhesive has become dry to the touch. Do not install flooring into wet adhesive on non-porous substrates. Roll the installation in both directions with a 100 lbs roller. 3-section roller immediately after flooring is placed.  

IMPORTANT: Do not use Armstrong S-995 as a releasable adhesive. Loss of adhesion can result if the flooring is not installed within the working time of the adhesive.  

PLEASE NOTE: Due to the many additives being entrained or topically coated on concrete substrates, it is critical that a bond test be performed. Some treatments will repel any sealers or adhesives. If usage instructions are not completely followed, DO NOT USE THIS PRODUCT. 

TRAFFIC: Follow Armstrong Flooring’s installation guidelines; otherwise restrict foot traffic for 24 hours after installation. No heavy traffic, rolling loads or furniture placement for 48 hours after installation. Allow at least 48 hours following the installation before conducting wet cleaning procedures or initial maintenance. Additional time may be necessary if the installation is over a non-porous substrate. 

CLEAN UP: Dry– clean, white cloth and mineral spirits Wet– clean, white cloth with neutral detergent and water

SUBSTRATE CONDITIONS: HVAC must be in operation and interior ambient air temperature must be maintained between 65-85°F for at least 48 hours prior to, during and continuously after the testing, preparation, and final installation.

IMPORTANT: Use the specified trowel and replace the trowel blade when worn to ensure proper spread rate. Adhesive application must be sufficient to achieve 100% transfer or contact of adhesive to the backing of the floor covering.  

LIMITATIONS: Not for outdoor use. Shelf life 2 years from date of manufacture in unopened container. Store indoors at a temperature between 65-95°F. Cannot be used over substrates that have been chemically cleaned. A bond test MUST be performed. Do not allow product to freeze. Seam preparation and heat welding of commercial seams in vinyl sheet must not be performed before the minimum 2-hour adhesive cure time or adhesive displacement could occur. Over non-porous substrates along with job site conditions, extended curing time of the adhesive may be required before heat welding.

DISCLAIMER: Users should determine the suitability of this information or product for their own particular purpose or application. This adhesive does not protect floor coverings from the effects of pH and moisture. Please follow Armstrong’s flooring installation instructions, paying special attention to moisture and pH limitations. Armstrong S-995 adhesive is not a moisture barrier and should not be installed/treated as such. This adhesive is not a substrate moisture sealer, does not form a protective barrier, and is only warranted to maintain an adhesive bond when used over bare concrete substrates conforming within the specified restrictions of ASTM 2170 in-situ Relative Humidity and pH readings. A functional working moisture barrier/retarder under the existing slab must be in place to use this product.  

Recommended Substrates

Will bond to all substrates listed below, but refer to the flooring installation system for specific installation recommendations:

DO NOT USE OVER: Concrete with excessive moisture and/or alkali; existing cushion-backed resilient flooring; substrates treated with fire-retardant chemicals, fungicides, preservatives, release agents, adhesive removers, sealers, curing compounds or other incompatible treatments
