Flooring Adhesives - SikaBond®-T17

One-component, low odor, polyurethane adhesive for wood flooring

SikaBond®-T17 is a one-component, low odor, moisture cured polyurethane adhesive for full surface bonding of wood flooring. SikaBond®-T17 will tenaciously bond wood to most surfaces, including concrete, plywood, and leveling and patch underlayments that have been properly prepared.

• 100% Elongation
• Bond up to 3/4" solid and engineered wood
• Low odor
• Excellent workability
• Fast curing
• Suitable for common types of wood floors
• Suitable for in-floor radiant heat installation
• Contains no water
• Tenacious bond

Usage

SikaBond®-T17 may be used to bond all engineered wood flooring, solid flat-milled shorts and solid shorts designed by the manufacturer for glue down applications. This adhesive can also be used for many other bonding applications that are common for light commercial and residential applications including acoustic rubber underlayment systems.

Application

Application Information

Sag Flow

Consistency: Spreads easily, holds ridges after troweling

Ambient Air Temperature

Room temperature between 60°F (15°C) and 90°F (35°C). For ambient temperatures the standard construction rules are relevant. Follow all wood floor manufacturer’s acclimation and room temperature requirements.

Relative Air Humidity

Between 40% and 70% during installation is best for adhesive. See wood floor manufacturer for wood requirements.

Substrate Temperature

During laying and until SikaBond®-T17 has fully cured, substrate temperature should be greater than 60°F (15°C) and in case of radiant heating, less than 70°F (20°C). For substrate temperatures, the standard construction rules are relevant.

Substrate Moisture Content

For use as an adhesive only: SikaBond^® T-17 is not affected by moisture or vapor transmission. For protection of the wood, follow the wood floor manufacturer’s requirements for subfloor moisture. If substrate is not acceptable, use SikaBond® T-17 at recommended coverage rate as All-in-One or Sika® MB. See Technical Data Sheet for proper instruction.

For use as an adhesive and moisture membrane: Concrete moisture vapor emission rate (MVER) may not exceed 8 lbs. per 1,000 sq.ft. (5,44 kg per 92,9 m²) per 24 hours, anhydrous calcium chloride test (ASTM F1869). Do not install when the relative humidity (RH) of the concrete slab exceeds 85% (ASTM F2170).

Curing Rate

Floor may accept light foot traffic after:

• at 45-50 SF/gal (P5 trowel): after 6-8 h
• at 30-35 SF/gal (SC+MB trowel): after 12 h

(depending on climatic conditions and adhesive layer thickness)

Floor can be sanded after 18 hours

Skin Time / Laying Time

~ 45-60 minutes

Consumption

Coverage

• Coverage must be monitored to ensure accuracy of application. Trowel angle may prevent proper coverage.
• Applicator is responsible for periodic inspection of the trowel to check for excessive wear. Worn trowels must be replaced immediately.
• In case of uneven substrates, it may be necessary to use a notched trowel with bigger notches (avert hollow sections).
• Coverage must be monitored to ensure accuracy of application. Trowel angle may prevent proper coverage.
• Trowel size is recommended to obtain proper coverage larger sizes are acceptable. Excessive amounts of adhesive may cause wood flooring to slide while placing check coverage during installation.
• P5 trowels should be used at 90° angle, SC+MB trowel or 1/4 in. (6.3 mm) x 1/4 in. (6.3 mm) V-notch at 45° angle to subfloor to get stated coverages.

• Substrate Quality: Structurally sound, clean, dry, homogeneous, even, free from grease, dust and loose particles, paint, laitance, and other poorly adhering particles must be removed.
• The P5 and SC+MB trowel are available from Sika.

Application Steps

SUBSTRATE PREPARATION

SikaBond®-T17 can be used on properly prepared, structurally sound concrete, cementitious patch/underlayments, chipboards, ceramic tiles, plywood. For on-grade sub-floors Sika® recommends the use of Sika® MB for best protection against sub-floor moisture - moisture testing is required by the wood flooring manufacturer for best results with the wood flooring products. Below grade applications are generally not recommended unless proper precautions are taken to protect the wood flooring from sub-floor and in-room humidity extremes. Sika recommends the use of Sika® MB over any dry, gypsum based sub-flooring to enhance surface strength. Preparation is a critical step in the installation process and will ensure a successful long term tenacious bond. All concrete, cement screed and gypsum based subfloors must be structurally sound, clean, dry, smooth; free of voids, projections, loose materials, oil, grease, sealers and other surface contaminants. Thoroughly clean with an industrial vacuum. Remove laitance or weak areas mechanically and thoroughly. For application over ceramic tiles it is necessary to grind tile surfaces and clean thoroughly with an industrial vacuum. For substrates with old well bonded adhesive or adhesive residue use Sika® MB - see Sika® MB data sheet for installation instructions and proper details. If surface contains asphalt (cutback) adhesive, follow the Resilient Floor Covering Institute “Recommended Work Practices” for removal. When the asphalt (cutback) adhesive is sufficiently removed use the Sika® MB to help promote adhesion to the subfloor or use a Sika® Level patch/level product in conjunction with the correct primer. SikaBond®-T17 will adhere to most common patching/ levelling compounds. Due to differences in asphalt based adhesive types and performance capabilities, applicator must verify that preparation of the surface is sufficient prior to using Sika® MB or Sika Level patch/level compound. Due to differences in asphalt-based adhesive types and performance capabilities, applicators must verify that preparation of the surface is sufficient prior to using Sika® MB or Sika® Level patch/ level compound. For unknown substrates.
