Easy Flowing Polyurethane Wood Floor Adhesive

DESCRIPTION

Surtek 3546 is a one component easy flowing polyurethane adhesive for wood floor installation. It cures fast, and is solvent free, environmental friendly.

ADVANTAGES

1-component, ready to use Solvent free

Fast cure

Floor can be sanded after 12 hours (full surface bonding, +23°C/50%r.h., up to 1 mm adhesive thickness)

Excellent workability, very easy to extrude Good initial tack

Odorless

Elastic, footfall sound-dampening adhesive Suitable for most common types of wood floors

Especially suitable for problematic woods including beech, maple and bamboo Suitable for bonding wood floors directly onto old ceramic tiles

Reduces stress to the substrate: the elastic adhesive reduces stress transfer between the wood floor and the substrate

Suitable for use with sub floor heating Compensates for some substrate unevenness Adhesive can be sanded

CHARACTERIST

*= at 23°C and 50% rh.

APPLICATION FIELDS

For Full Surface bonding:

Solid and engineered wood floors (strips, longstrips, planks, panels, boards), mosaic parquet, industrial parquet, lam parquet, wood paving (residential) as well as chip boards can all be fully bonded

Elastic Bonding of skirting boards/ baseboards and door thresholds etc.

APPLICATION DETAILS

Consumption:

Full Surface Bonding:

700 - 900 g/m2 with notched trowel B3 (acc. To IVK guidelines) or 3/16" 1/8" 1/8" (engineered strips / planks, mosaic parquet etc.).

800 - 1000 g/m2 with notched trowel B11 (acc. to IVK guidelines), AP 48 or 3/16" 3/16" 3/16" (solid wood, engineered planks / panels, industrial parquet, wood paving (residential), chipboards etc.).

For bonding of long or wide boards or on uneven substrates it may be necessary to use a notched trowel with bigger notches (to prevent hollow sections).

Beaded Application:

~ 44 ml per running meter = 250 - 500 g/m2, dependent on bead spacing (solid wood boards, 3-ply engineered wood, chipboards).

Substrate Quality:

Clean and dry, homogeneous, even, free from grease, dust and loose particles. Paint, laitance and other poorly adhering particles must be removed. Standard construction rules must be observed.

Substrate Preparation:

Concrete / cement screed:

Must be ground and thoroughly cleaned with industrial vacuum cleaner.

Anhydrite screed / Anhydrite flowable screed: Must be ground and thoroughly cleaned with industrial vacuum cleaner shortly before bonding starts.

Broadcast mastic asphalt

Must be primed with Comens Primer. Instructions for use, see Technical Data Sheet for Comens Primer.

Glazed ceramic and old ceramic tiles: Degrease, clean with Comens Cleaner or grind the tile surfaces and vacuum thoroughly.

Wood-/gypsum boards (e.g. chipboards, plywood):

Glue / screw the boards to the substructure. They must be fixed to the substrate. For floating sub floors, please contact our Technical Service Department.

Other substrates:

Please contact our Technical Service Department for advice and assistance.

Surtek 3546 can be used without priming on cementitious floors, anhydrite floors, chipboards, concrete and ceramic tiles.

For broadcast mastic asphalt, cementitious floors with an excessive moisture content and for use over old adhesive residues or on weak substrates use Comens Primer. For detailed instructions consult the Product Data Sheet of Comens Primer or contact our Technical Service Department.

APPLICATION INSTRUCTIONS

Application:

Full Surface Bonding:

Surtek 3546 is applied to the prepared substrate directly from the pail and uniformly distributed by notched trowel. Press the wood floor pieces firmly into the adhesive so that the underside is fully wetted. The pieces can then be joined together using a hammer and an impact block. Many types of wood floors have to be tapped from the top. A distance of 10 - 15 mm from the wall to the wood floor must be maintained.

Beaded Application:

After inserting the sausage into the gun, extrude a triangular shaped bead of adhesive approximately 10 mm high and 8 mm wide at 100 - 250 mm centres (dependent on wood floor type) on the prepared sub floor. Press the wood pieces firmly into the adhesive (at right angles to the adhesive beads). The elements can then be joined together using a hammer and an impact block. The required distance from the wall to the wood floor in the laying instructions from the wood floor manufacturer must be maintained.

Note: The laying instructions of the wood floor manufacturer must be observed.

PACKAGING

600 ml sausage (20 sausages per box);

STORAGE AND SHELF LIFE

9 months from date of production if stored in undamaged, original sealed containers, in dry conditions and protected from direct sunlight at temperatures between +10°C and +25°C.

CAUTION

To avoid allergic reactions, we recommend the use of protective gloves. Change soiled work clothes and wash hands before breaks and after finishing work.

Local regulations as well as health and safety advice on packaging labels must be observed.
