DESCRIPTION

Bostik Climb™ is a one-component, easy gunning, non-sag adhesive

that is specifically formulated for hardwood flooring, planks and blocks

on interior, above-grade walls and installation of stair tread caps. The

Climb™ formula has superior green grab (grab strength while wet) and

cures quickly to form a tenacious bond. Once cured, Climb™ remains

tough yet flexible for extreme durability, helps reduce stair squeaking,

and reduces the sound of footsteps on the stairs. This specialty

formulation is also easy to clean off of flooring, prefinished tread caps

and risers even after cure. Climb™ has 0% solvents and low odor.

ELASTOMERIC PERFORMANCE

Climb™ has superior elasticity allowing the adhesive to move with

the wood as it expands and contracts with changes in humidity and

temperature over the life of the stair tread or hardwood flooring.

APPLICATIONS

•

Adhesion to sub floor assemblies of plywood, OSB, solid hardwood,

engineered hardwood, or existing wood floor treads & risers.

•

May eliminate squeaks and nail pops when used in conjunction

with mechanical fasteners

•

Adhesion to drywall, plywood, concrete, or masonry in dry, above-

grade applications

LEED

CONTRIBUTION

This low VOC formulation (as calculated per SCAQMD Rule 1168), may

contribute toward LEED

credits under section NC-v2.2 EQ 4.1: Low-

Emitting Materials—Adhesives & Sealants.

DIRECTIONS FOR USE

Read and understand data sheet completely before beginning

installation. Follow industry standards, as well as stair tread cap

manufacturer’s recommendations for acclimation, design, layout

and application of wood flooring material. If jobsite conditions are

outside of flooring manufacturer’s recommendations, take necessary

corrective actions. WARNING: On stair tread cap applications,

Climb™ is to be used in conjunction with mechanical fasteners to

prevent movement of the stair tread cap while the adhesive cures.

Failure to use appropriate mechanical fasteners may lead to slipping

or falling down the staircase. See installation instructions for more

detail.

SURFACE PREPARATION

Surface must be clean, dry and smooth; free of voids, projections,

and loose materials. Finishes, oils, greases, sealers, waxes and all

other surface contaminants must be sanded down to bare wood.

INSTALLATION

Cut the tip of the nozzle at a 45 degree angle to produce a bead of

adhesive between 1/4" and 3/8" in diameter. Puncture the foil seal

inside nozzle.

Hardwood Wall Planks: Gun adhesive onto the back of the wall plank

in an "S" pattern within 1" (2.5cm) of long edges and repeating every

6-8" (15-20cm). Press wall plank firmly into place and secure with

brad nails along the tongue every 6-8" to ensure the board does not

slip or slide before the adhesive is fully cured.

Stair Treads Caps: Dry fit all parts prior to application of the adhesive

to ensure a proper fit. Gun adhesive onto the back of the stair tread

cap approximately 1" from the edge around the entire perimeter, then

apply an “S” pattern repeating every 6-8" between the perimeter

beads. Run one additional bead along the corner of the front molding.

Press tread cap firmly into place and secure with brad nails along the

back edge every 6-8" to ensure the tread does not slip or slide before

the adhesive is fully cured. Weights applied to each side of the stair

tread until cure are recommended to improve contact.

Reposition work, if necessary, prior to adhesive skinning; usually in

15 minutes. Lower relative humidity and temperature will extend

curing time. Although relatively easy to remove Climb™ from the

face of prefinished hardwood even after cure, it is recommended to

clean with a non-abrasive towel as you work prior to cure.

Stair Risers: Dry fit all parts prior to application of the adhesive to ensure

a proper fit. Gun adhesive onto the back of the stair riser approximately

1" from the edge around the entire perimeter, then press firmly into

place and secure with a few brad nails around perimeter.

CLEAN UP While Climb™ bonds tenaciously to wood, it is designed not to bond with most finishes on pre-finished flooring making it relatively easy to remove from the finish even after cure. Although it is relatively easy to remove after cure, it is recommended to clean with a nonabrasive towel as you work prior to cure. After cure, adhesive may be removed with a plastic scraper and dry, non-abrasive towel, taking care not to damage the finish. Immediately clean all tools and equipment before material cures.
