Description n1-component, ready-to-use polyurethane adhesive nSikaBond-T53: Fast curing for early green strength and superior holding power Color White Packaging 20 oz (600 ml) unipacs, 20 unipacs per box Shelf-Life 12 months from date of production if stored in undamaged original sealed containers, in dry conditions and protected from direct sunlight at temperatures between +50°F and +77°F (+10°C and +25°C) Application Details - Sika AcouBond-System: 1 roll SikaLayer-03 + 1 box SikaBond-T53 = 269 SF (25 m2) Consumption Approximately 13.4 ft2 per sausage (1 box of 20 sausages cover 269 ft2). All cut-outs must be filled. Use application tip with triangular cut out to a 0.32 x 0.4 inch (8 x 10 mm) opening. Tips are included in the shipping carton. Tips can be reused. Do not discard. Allow adhesive residue to cure in the tip min. 24 hours and then remove. Substrate Quality Clean and dry, homogeneous, even, free from grease, dust and loose particles. Paint, laitance and other poorly adhering particles must be removed by mechanical means. Substrate Preparation SikaBond-T53 can generally be used without priming on properly prepared, structurally sound substrates - concrete, cement floors, chipboards, ceramic tiles plywood and hardwood. For on-grade sub-floors Sika recommends the use of Sika Primer MB for best protection against\ subfloor moisture – moisture testing is required by the wood flooring manufacturer for best results with the wood flooring products. Below grade applications are generally not recom- mended unless proper precautions are taken to protect the wood flooring from subfloor and in- room humidity extremes. Sika recommends the use of Sika Primer 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. The surface must be prepared by mechanical means, e.g. sanding, grinding, shotblasting, and clean thoroughly with an industrial vacuum. 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 adhesive or adhesive residue use Sika Primer MB see Primer 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 Primer MB to help promote adhesion to the subfloor – or use an industry approved levelling compound over the cutback residue. SikaBond-T53 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 suf- ficient prior to using Sika Primer MB or patch/level compound. For unknown substrates please contact Sika Technical Services for best practices at 800-933-SIKA.

Construction Application Conditions/Limits Substrate Temperature During laying and until SikaBond-T53 has fully cured substrate temperature should be greater than 60°F (15°C) and in case of floor heating, less than 70°F (20°C). 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. Substrate Humidity Moisture requirements are set forth to protect the wood flooring products that can expand and contract with different moisture levels. SikaBond-T53 is not affected by moisture or vapor transmission. The below guidelines are included to provide the best practices in moisture vapor testing that exists today. Permissible substrate moisture contents are listed on the below chart. For more information on the use of the CM method please contact Troy Corporation at 973-443-4200. The National Wood Flooring Association recommends the use of moisture testing devices that identify actual moisture content in percentages (%). For best results in measuring the moisture levels in cement based subfloor use the Tramex measuring device to find the highest reading in the application area and then run the CM method at that highest point to determine the worst case. As a general guideline for floors with no in-floor heating if the Tramex is below 4% the Sika Primer MB will not be necessary and between 4% and 6% Sika Primer MB will be required - however, the CM method must be used to make final determination of concrete moisture levels - use chart above. For moisture content and quality of substrates the guidelines of wood floor manufacturer must be observed. Relative Air Humidity Between 40% and 70% Application Instructions Application Method/ Roll out SikaLayer-03 mat on the properly prepared substrate, Tools parallel to the laying direction of the wood floor. The mat does not get glued to the subfloor – unless adhesive is used to keep the mat from sliding. The foam mat should be placed approximately 3⁄4” away from walls and approximately 3⁄4” away to any adjacent mat. This will allow for placement of both a perimeter adhesive bead and an adhesive bead between any two adjacent mats. To apply the adhesive a sausage-gun is required. Apply the adhesive with manual-or air-pressure-gun into all cut-outs with the supplied triangular nozzle. Also apply adhesive beads at room perimeters and between adjacent mat as mentioned above. Take care to place only enough adhesive to allow sufficient time to place wood into adhesive while the adhesive is still very wet. Filling of all cut-outs is a must. The nozzle must be held vertical to the substrate - 90 degree angle. Take care not to apply adhesive on top of the mat. Position wood boards and firmly press into the adhesive until they lay tight on the SikaLayer mat. The wood boards can then be joined together using a rubber mallet or hammer and an impact block. Follow the required distance from the wall to the wood floor in the laying instruction from the wood floor manufacturer. Spacers should be used to ensure perimeter space is maintained. When working at or near room perimeters, door ways or tight areas additional slots may be needed in the SikaLayer-03 mat to accommodate short edge pieces and to ensure enough adhesive to securely hold wood down. Use razor knife to make cut outs in mat the same size as existing pre-cut openings.

Construction Fresh, uncured adhesive remaining on the wood floor surface must be removed immediately with Sika Equipment Cleaner, mineral spirits, or a standard industry cleaning solvent. Failure to do so could result in a dulled finish. The laying instructions of the wood floor manufacturer as well as standard construction rules must be observed throughout the installation process. Note: For Solid and Wide Engineered Hardwood applications: Sika recommends the use of clamps to keep joints tight – for most projects a set of 5 will be adequate. If bowed boards are expected, Sika recommends placing several rows of straight boards across length of room and allow to cure overnight – these will form starter rows that will act as anchor for the clamps. For moderately bowed boards – clamp boards from the starter row. Clamp each individual row or several rows – if clamping several rows this must be done while adhesive is still wet. Clamps can then be loosened until successive rows are place and clamped accordingly. Be careful not to over-tighten. Best practice is to leave clamps in place when work is stopped for the day. For severely bowed boards – cut boards down to shorter pieces so that bow is removed. For situations where wood flooring does not rest flat - Sika recommends as a best practice the use of weights to ensure intimate contact between the wood-adhesive-substrate. Leave clamps and/or weights on critical areas for a minimum of 12 hours. Clean Up All tools should be cleaned immediately after use with Sika Equipment Cleaner. Any adhesive that is permitted to cure on the tool will need to be removed by mechanical means. Use a dry towel and a good quality adhesive remover that will not damage the wood finish to remove adhesive from pre-finished wood surface before it cures. Finger prints or small amounts of adhesive residue can be removed immediately from pre-finished wood using adhesive remover. Remove any adhesive residue from hands using immediately soap and water or other commercial hand cleaner. Limitations n Sika AcouBond-System should be used with 2” (5 cm) wide or larger structurally sound solid hard- wood and structurally sound engineered hardwood that can be either floated or nailed or stapled. n SikaBond-T53: Bonds solid wood flooring up to 8” (18 cm) wide and engineered planks up to 14” (36 cm) wide directly to concrete substrates. n Minimum wood length 1’ (one foot) is required to ensure that wood spans 3 (three) adhesive strips for standard placement. No maximum wood length. n Structurally sound sufficient tongue and groove stability is necessary for this system. n Minimum application temperature 50°F n Sika recommends following the wood floor manufacturer’s recommendations, as to acclimation, maximum moisture content and application conditions. n Do not use on wet, contaminated or friable substrates. n Sika recommends the use of Portland Cement based patching and leveling compounds for best results. n Gypsum-based subfloors are very susceptible to excess moisture and will be degraded if exposed to excess moisture from below or above. n Do not use in areas subject to hydrostatic head or in areas subject to secondary source of moisture. n Do not use over concrete with curing compounds, sealers or other surface treatments that could impact the adhesion. n This adhesive will not prevent moisture related damage to wood flooring installations. n Subfloor should be level - do not use adhesive as a leveling agent. n Cutback or other asphalt based adhesives should be removed. n Chemically treated woods (ammonia, wood stain, timber preservatives, etc.) and woods with high oil con- tent must be tested for adhesion prior to application. n Adhesive should be kept above 60°F for best workability. n Sufficient ambient moisture is necessary for proper curing. n Solid wood applications are best performed by an experienced installer. n When bonding solid wood Sika recommends the use of straps to fully connect tongue and groove - espe- cially when wood pieces are not perfectly straight - a starter row may be appropriate to form a fixed loca- tion to tighten straps. n Installations over radiant heat require that slab temperature be kept below 70°F during installation and for 48 hours after installation - then raised slowly up to final desired temperature. Follow wood floor manufacturer’s temperature guidelines. Wood floors in noninsulated areas or areas without a damp proof membrane, must only be installed after the application of Sika Primer MB to control the moisture, if within product limitations. For detailed instructions consult the Product Data Sheets or contact our Technical Service Department. In case of chemically pre- treated types of wood floors (eg. ammonia, wood stain, timber preservative or woods that have been pre/ sealed on the back side) and woods with high oil content SikaBond should only be used if adhesion tests are run by applicator prior to starting application. Do not use on PE, PP, TEFLON, and certain plasticized synthetic materials. (Carry out pretrials). Some primers can negatively influence the adhesion of SikaBond (pretrials suggested). Do not expose SikaBond to alcohol; his will impact the curing of the SikaBond.
