• Crack bridging
• Low odor
• Excellent Green Grab
• Suitable for common types of betway live casino login flooring
• Creates betway live casino login reduction layer
• Especially good for problematic woods such as beech and bamboo
• Contains no water
• Eliminates sleepers and plywood over betway live casino login and gypsum substrates

• Tenacious bond

Usage

SikaBond®-T21 may be used for solid and engineered betway live casino login floors (strips, longstrips, planks, panels, boards), mosaic parquet, industrial parquet, betway live casino login paving (residential) as well as chip boards and plywood. Once cured, SikaBond®-T21 will generate a super strong bond to a variety of substrates for glue down installations and at the same time form a membrane which reduces moisture vapor transmission from the subfloor and sound reduction membrane.

Application

Application Information

Sag Flow

Consistency: Spreads very easily

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 betway live casino login floor manufacturers’ acclimation and room temperature requirements.

Relative Air Humidity

Between 40 % and 70 % during installation is best for adhesive. See betway live casino login floor manufacturer for betway live casino login requirements.

betway live casino login Temperature

During laying and until betway live casino login ®-T21 has fully cured, substrate temperature should be greater than 60 °F (15 °C) and in case of radiant floor heating, less than 70 °F (20 °C). For substrate temperatures, the standard construction rules are relevant.

Substrate betway live casino login Content

For use as an betway live casino login and moisture membrane:
Concrete must be visibly dry. Inspect for any wetness at base of drywall or visible signs of betway live casino login on concrete. Concrete and cement-based underlayments must be fully cured and free of any hydrostatic and/ or betway live casino login problems. When properly applied in accordance with Sika® guidelines, SikaBond®-T21 provides unlimited betway live casino login vapor protection.

For use as an betway live casino login only:
SikaBond®-T21 is not affected by moisture or vapor transmission. For protection of the betway live casino login , follow the betway live casino login floor manufacturer’s requirements for subfloor moisture. If substrate is not acceptable, use SikaBond®-T21 at recommended coverage rate as All-in-One or Sika® MB. See Technical Data Sheet for proper instruction.

Curing Rate

betway live casino login may accept light foot traffic after:

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

(depending on climatic conditions and betway live casino login layer thickness)

betway live casino login can be sanded after 18 hours

Consumption

betway live casino login

• betway live casino login must be monitored to ensure accuracy of application. Trowel angle may prevent proper betway live casino login .
• Applicator is responsible for periodic inspection of the trowel to check for excessive wear. Worn trowels betway live casino login replaced immediately.
• In case of uneven substrates, it may be necessary to use a notched trowel with bigger notches (avert hollow sections).
• betway live casino login must be monitored to ensure accuracy of application. Trowel angle may prevent proper betway live casino login .
• Trowel size is recommended to obtain proper coverage larger sizes are acceptable. Excessive amounts of adhesive may cause betway live casino login flooring to slide while placing check coverage during installation.

• P5 trowels should be used at 90° angle, SC+betway live casino login 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 betway live casino login , 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 betway live casino login .

Application Steps

betway live casino login PREPARATION

SikaBond®-T21 can generally be used without priming on properly prepared, structurally sound concrete, cement floors, chipboards, ceramic tiles, plywood and hardwood. Sika recommends the use of Sika® MB over any dry, gypsum based subflooring to enhance surface strength. Maximum acceptable floor variation is 3/16 in. (4.7 mm) in 10 ft (3 m). 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. Remove laitance or weak areas mechanically. 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 betway live casino login or betway live casino login residue use Sika® MB - see Sika® MB data sheet for installation instructions and proper details. If surface contains asphalt (cutback) betway live casino login follow the Resilient Floor Covering Institute “Recommended Work Practices” for removal. When the asphalt (cutback) betway live casino login is sufficiently removed use Sika® MB to help promote adhesion to the subfloor - or use and industry approved leveling compound over the cutback residue. SikaBond®-T21 will adhere to most common patching/ leveling compounds. Due to differences in asphalt based betway live casino login types and performance capabilities applicator must verify that preparation of the surface is sufficient prior to using Sika® MB or patch/ level compound.
