TechSlate Glue-Down Installation

Detailed instructions

Techslate is a durable floating flooring system designed with the Uniclic® interlocking profile and a fully waterproof surface layer. While it is typically installed as a floating floor, glue-down installation is recommended in spaces where there’s a higher chance of water intrusion—such as bathrooms, basements, and laundry areas—to prevent moisture from seeping beneath the floor and causing mold or mildew.

Adhesives Recommended for Glue-Down Application

For best results, use a low-moisture or moisture-free adhesive that’s typically used for parquet wood floors. Approved products include:

• MAPEI Ultrabond ECO 995 – a one-part urethane adhesive with built-in moisture protection

• SikaBond® T55 – a low-VOC polyurethane adhesive known for strong bonding and elasticity

These adhesives maintain the structural integrity of Techslate’s core while preventing water-related damage.

Tools & Supplies Checklist

You’ll need the following materials and tools:

• Techslate planks

• Compatible adhesive (ECO 995, T55, or equivalent)

• V-notched trowel (1/4″ or 1/8″, depending on adhesive)

• Chalk line for layout guides

• 100-lb flooring roller

• Moisture meter (for subfloor testing)

• Measuring tape, utility knife, spacers

Installation Instructions

Step 1: Subfloor Preparation

• Ensure the subfloor is smooth, dry, and structurally sound

• Suitable surfaces include: concrete, plywood, OSB, or self-leveling compounds

• Confirm moisture levels with a moisture meter; they must meet the adhesive manufacturer’s limits (e.g., ≤3 lbs MVER)

• Thoroughly vacuum to remove all dirt and debris

• Apply a moisture barrier primer if the adhesive brand recommends it for concrete

Step 2: Acclimation

• Allow Techslate to sit in the room where it will be installed for 24 to 48 hours

• Maintain indoor temperatures between 65°F and 78°F (18–26°C) during this time

Step 3: Planning the Layout

• Use a chalk line to mark straight reference guides on the subfloor

• Work in sections to avoid stepping into areas where adhesive has already been applied

Step 4: Applying Adhesive

• Refer to the adhesive manufacturer’s directions for correct trowel size and open time

• Use the trowel to spread adhesive evenly

• Apply only as much adhesive as can be covered within the adhesive’s working time (usually 30–60 minutes)

Step 5: Installing Techslate Planks

• Place the planks directly into the wet adhesive and press firmly into place

• Leave a small expansion space (2–3 mm) around the room perimeter

• While Techslate has a Uniclic® locking system, you can trim off the groove to convert to a butt joint for easier glue-down

• Avoid sliding planks across adhesive—drop them into place and shift slightly to align

Step 6: Rolling the Floor

• Use a 100-pound floor roller within 30 minutes of laying each section

• Roll in both directions to ensure full adhesive contact

Step 7: Cleaning Up

• Immediately remove any adhesive that seeps out between joints

• Use a damp cloth or mineral spirits, depending on the type of adhesive used

Step 8: Curing Time

• Follow the adhesive’s guidelines for curing:

  • Wait 12–24 hours before walking lightly on the floor

  • Wait 72 hours before moving in heavy furniture or cleaning

• Avoid exposing the floor to water during this time

Additional Tips & Warnings

• Do not install over radiant heat systems exceeding 27°C (80°F) unless your adhesive is rated for it

• Never install over wet or visibly damp subfloors

• In flood-prone spaces, seal edges and expansion gaps with waterproof caulking for added protection
