Description

LAYBOND GRIPFILL(tm) is a solvent-borne, filled rubber resin, developed to
bond virtually any rigid materials together, regardless of the evenness of the
surfaces.

Uses

LAYBOND GRIPFILL(tm) is a high strength, one part, gap-filling adhesive
specially formulated to bond a large variety of materials, such as plywood,
blockwood, chipboard, hardboard, laminated plastics, uPVC (excluding foamed
PVC), rigid insulation materials (excluding expanded polystyrene), metal
sheeting (including aluminium, steel, galvanised iron, tin plate and non-ferrous
metals) to themselves or to brick, stone and breeze block, sand/cement
screeds, concrete, plaster, plasterboard and insulation boards. If further details
of a particular application are required, please contact our Technical
Department at the address below.

LAYBOND GRIPFILL(tm) is suitable for bonding aluminium and uPVC stair
nosings, carpet edging strips, carpet grippers, building boards, timber battens,
etc. to stairs, floor boards and walls.

LAYBOND GRIPFILL(tm) can also be used successfully for bonding wall
signs, window frames, sink units, fitted furniture (including light fittings)
to a variety of surfaces; in the building of home extensions, caravans and cars.

Although LAYBOND GRIPFILL(tm) will bond mirrors, care should be taken to
ensure no reaction takes place with the coating, as this may occasionally occur.

Where LAYBOND GRIPFILL(tm) is used externally, it must be protected from
driving rain, ponding water or permanently wet situations.

Preparation

Surfaces to be bonded must be clean, structurally sound, dry and free from
dust and loose material. Porous surfaces, such as plaster and fibre cement
board, should first be primed with LAYBOND ISOBOND (diluted 1:6 with clean
water) and allowed to dry thoroughly before LAYBOND GRIPFILL(tm) is applied.
Building panels should be cut to shape beforehand.

Application

Fix the cartridge into the extruder.

Cut the nozzle to the desired width and angle and push a nail through the
nozzle to break the seal at the base.

a) Stair Nosings, Window Frames, etc.

Apply a continuous bead (usually 6mm in diameter) to the surface being
bonded. Position on the substrate, if possible by sliding into place and apply
pressure overall. If the object is to be applied to a vertical surface, temporary
mechanical support (eg. panel pins, masonry nails, etc) may be required.
Allow to dry overnight prior to any further operation eg. fixing boards to battens, etc.


b) Wall Panels

For most work, LAYBOND GRIPFILL(tm) should be applied as a bead approximately
6mm diameter to the rear of the panel. Extrude a continuous bead around the
panel approximately 25mm from the edge. Additional beads should then be
applied across the panel at 600mm centres (450mm for heavy panels).

Immediately present the panel to the wall slightly above its required position
and applying pressure slide it into place in order to break any surface skin.
Press firmly to ensure maximum overall contact, using a soft mallet if necessary.
Continue as above with further panels making sure they are flush with each other.
Any adjustment must be made within 5 minutes of placing.

Alternatively, LAYBOND GRIPFILL(tm) may be applied in the form of blobs
approximately 10-12mm in diameter at 300mm centres, in rows either 450mm
or 600mm across the board (depending upon the weight as above). The blob
application is not recommended when bonding plastic materials.


c) Impervious Materials

Where two impervious materials are to be bonded, apply LAYBOND GRIPFILL(tm)
as above, press firmly together and break the bond by pulling away immediately
ensuring good transfer has occurred. Wait for approximately 10 minutes and
re-bond the two materials.

Safe Handling Precautions

Flammability: Keep away from sources of ignition including pilot lights and
sparks (see Note). Take precautionary measures against static discharge.
Ensure thorough ventilation. DO NOT SMOKE.

Note: Electric motors, light/power switches and steel tools may generate
sparks sufficient to ignite the product or its vapour, resulting in explosion and/or fire.

Skin Contact: Contains solvents which cause de-fatting of the skin and, in
extreme circumstances, dermatitis. Avoid contact by careful working and use
of barrier cream on hands, arms and other exposed areas, or gloves. Remove
contamination with a proprietary cleanser and wash with soap and water.

Eye Contact: Could be harmful. In the event of accidental contact, irrigate
eyes immediately with clean water for 15 minutes and obtain medical attention.

Inhalation: Gives off irritating vapours. Use only in a well ventilated area and
use respirators containing cartridges suitable for use with organic solvents where
necessary. In the unlikely event of discomfort as a result of inhalation, remove
the person to fresh air and obtain medical attention.

Oral Ingestion: With proper handling this should not occur. The possibility can
be minimised by not consuming food in the working area and by washing hands
thoroughly before eating, drinking or smoking.

Spillage: Spilt material should be mopped up immediately with an inert, absorbent
material, such as sand, and disposed of in accordance with regulations.

Disposal Of Containers: Do not leave empty containers on site where residue
could be a hazard to children, animals or the environment.

Remove any containers to a central disposal point.

Cleaning Of Tools

Carefully clean with white spirit before film has dried.

Cleaning Of Surface

Carefully clean with white spirit.

Containers

350ml cartridges and 310ml on request.

Storage Life

12 months under good storage conditions in original, unopened cartridges away
from direct heat and out of sunlight.

Storage Conditions

12 months under good storage conditions in original, unopened containers.
Keep out of direct sunlight at a temperature of between 5ºC and 40ºC. Store under
cover in tightly closed containers, in accordance with the Liquids and Liquefied
Petroleum Gases Regulations (1972).
