Wet out

2aGENERAL COATING and BONDINGApply the mixture with the brush as a

waterproof coating, or to pre-wet porousbonding surfaces before applying thickenedepoxy.

Dispense and mix

Read all directions, including safety informa-tion on Resin/Hardener packet, before us-ing. Prepare parts to be bonded. Check forproper fit. Bonding surfaces should beCLEAN, DRY and SANDED.

1Empty entire contents of a Resin/Hard-ener packet into the Handy Pack con-

tainer. Mix the resin and hardener togetherthoroughly using the square end of the mix -ing stick.

Apply epoxy, assemble and clamp partswithin fifteen minutes. Working and curetime will be shorter in warmer tempera-tures—longer in cooler temperatures.

Add Filler

3Thicken the remaining epoxy by stirringin filler until it reaches the desired con-

sistency. The mixture should be thickenough to fill gaps between mating surfaceswithout sagging. The more uneven or widerthe gap, the thicker the mixture should be.The mixture may be thickened to a verythick, peanut butter-like consistency formaximum gap filling or for filling and shap-ing low area or filling holes.

Apply thickened epoxy

4aApply thickened epoxy to the matingsurfaces using the mixing stick.

Clamp the parts in position using onlyenough pressure to assure good contactand prevent movement.

4bApply thickened epoxy to the cleanedhardware bonding surface, fastener

holes and threads. Position the hardwareand tighten fasteners until epoxy squeezesout. Do not over-tighten.

Important! Once resin andhardener are combined, youwill have 10-15 minutes ofworking time.

5bScrape off excess epoxy with thesquare end of the mixing stick. Wipe

away remaining residue using the alcoholcleaning pad or a paper towel and nail pol -ish remover. Allow 24 hours at 72°F beforesubjecting to load.

Shape or clean excess

5aIncrease bonding area by shaping ex-cess epoxy mixture into a fillet using

the round end of the mixing stick.

Apply reinforcing

6aAdd extra reinforcing to a joint by ap-plying fiberglass tape over the fillet.

Trim tape to the appropriate size then usethe brush to saturate the fabric with epoxyand smooth the fabric in place.

The fiberglass tape can be used to patchcracks and holes, or provide abrasion resis -tance to wear points such as stems andkeels or the edges of paddle blades andcenterboards.

2bHARDWARE BONDING Beforebonding hardware, pre-wet porous

fastener holes using the pipe cleaner.

Using epoxy

Mixing and CuringRead and follow the directions, includingsafety information, on the Resin/Hardenerpackets.Mixing resin and hardener together starts achemical reaction that transforms the com-bined liquid ingredients into a solid.Before the curing epoxy begins to gel in themixing container, about 10 minutes at 70°F(21°C), you must—• Apply and smooth epoxy if you are coat -

ing.• Apply epoxy, assemble and clamp parts if

you are bonding.• Wet out and smooth fabric if your are ap-

plying fiberglass reinforcing.• Spread the epoxy to a thin layer, to extend

the working and cure time.Epoxy cures faster in warmer temperaturesand in a thicker layer (as it is in the mixingcontainer). Epoxy cures slower in coolertemperatures and in thinner layers. A thinfilm of epoxy can take 2–3 hours to gel.The epoxy mixture will reach a workablecure in 5–7 hours. Clamps can be removedand the epoxy may be sanded, but it shouldnot be subjected to high loads for 24 hours.When a quicker cure is desired, applyingmoderate heat will reduce cure time.

Gluing tips• Before mixing epoxy, check all parts to be

bonded for proper fit. Gather all necessaryapplication tools and clamps. Keep a rollof paper towels handy.

• For maximum adhesion, be sure bondingsurfaces, including surfaces to be coated,are clean and dry. Sand all non-poroussurfaces with 80-grit paper.

• Use only enough clamping pressure tohold parts in place without moving. Useenough epoxy adhesive so that a smallamount will squeeze from the joint whenclamped. Avoid squeezing all of the epoxyout of the joint with too much pressure.

CleanupClean uncured epoxy from skin and clotheswith a waterless skin cleaner, followed bywashing with soap and water. Remove ex-cess epoxy from work surfaces with the flatend of a mixing stick or with paper towels.Cleanup residue with a solvent such as ace-tone or lacquer thinner.Because West System Inc. cannot control how this productwill be used, it makes no warranties, either expressed or im-plied, including no warranties of merchantability and fitnessfor purpose intended.
