To apply: Use full-strength. Rub or brush an even coat of Weldbond to all thoroughly cleaned surfaces to be bonded. Clamp lightly. This eliminates any problem of glue rinse-out caused by pressure, particularly important for hardwoods such as ash, walnut and oak. For warped wood or hard dense wood where heavy clamping is usually required, or when laminating, we recommend you use Weldbond PROFESSIONAL WOOD GLUE. It's designed for fast-clamp release or less than 30 minutes with a bonding strength of up to 3500 P.S.I.

For a smooth finish: All glue lines and drips can be removed up to 20 minutes after gluing, by washing thoroughly with warm water and sponge until surface is free of all glue. Let dry; then stain for a uniform finish.

End-grain bonding: Prime both surfaces with a solution of 1 part Weldbond and 5 parts water. Allow to dry and make the final bond with full-strength Weldbond applied to both surfaces. Light clamping only.

Economic strength: Even diluted, Weldbond provides an exceptional bond. Try thinning it with up to 25% water to make a lower-cost glue suitable for some applications such as dense wood and glass to glass.

For plywood, hardwood, gypsum board and plastic laminates on vertical surfaces: Prime porous surface with 1 part Weldbond and 5 parts water. Let dry. To bond a smooth surface, use concentrated Weldbond on both surfaces and bring together. If surface is rough or uneven, use a plaster or cement slurry to take up the unevenness. (To make a slurry, add plaster or cement to Weldbond to form a paste.) Brace large boards or hold in place with nails until set. Apply daubs no smaller than 2" in diameter, 16" apart. If placing foam plastic under the boards, support with tack strips, top and bottom, until set.

Ceilings and horizontal surfaces: Apply concentrated Weldbond to both surfaces and bring together. If a ceiling is to be covered with plywood, gypsum board or insul-board, the material should be tacked, weighed down, taped, or braced until dry (approx. 1 to 2 hours depending on temperature and humidity).

Fix parquet and strip flooring: Apply concentrated Weldbond to floor backing. To fix uneven surfaces, add a little plaster or cement to Weldbond to form a paste. Porous floors must be primed with 1 part Weldbond to 5 parts water.

Veneering: For extremely porous wood, seal surfaces with a mixture of 1 part Weldbond, 5 parts water. Allow to dry. Coat both surfaces with a mixture of 5 parts Weldbond, 1 part water. Let dry fully, then press together with a domestic iron at wool setting. For other woods, let Weldbond dry completely on the surface to be veneered, then apply veneer with a hot iron at medium or wool setting. Test iron by placing a piece of brown paper under it while veneering. Doing this will allow a too-hot iron to scorch the paper; not your veneer work.

Plastic Wood: Weldbond mixed with fine sawdust (wood flour) makes an excellent plastic wood filler of tremendous strength. Make up a paste with Weldbond and sawdust, or wood flour, to required consistency. Add stained tint if required. Apply in usual way, allow to dry thoroughly before doing any work on it. Repeat if shrinkage occurs.
