Agnew's Water Putty
Australian Made

Agnew’s Water Putty is proudly 100% Australian made and owned since 1929.

Agnew’s Water Putty, the original and the best since 1929

Agnew’s Water Putty is an excellent filler for patching and levelling wood, plasterboard, cement sheet, concrete, etc. Agnew’s Water Putty is particularly suitable if you need a hardwearing surface.

Agnew’s Water Putty sets hard, adheres permanently and fills to any depth without shrinking or cracking. It can be sawn, drilled and sanded. Agnew’s Water Putty is also ideal for architectural and hobby moulding.

Agnew’s Water Putty is not a flexible compound. Use only in an exterior situation if you have ensured that the substrate has a low propensity to expand and contract as the ambient temperature changes and have ensured that the putty is dry and then sealed.

Features and Benefits


Use Agnew’s Water Putty for lasting repairs

Agnew’s Water Putty is great for repairs as it sticks and stays put. Plus, it’s easy to use, dries rock hard, and never shrinks. It fills voids completely and is ideal for wood repair and plaster patches.

Fill Holes In Wood

Agnew’s Water Putty is ideal for filling knotholes, nail holes, oversized screw holes, and other defects in wood. Leave the putty uncoloured if it is to be painted, or coloured if it is to be matched with the wood.

Fix Door Bumpers

Tighten loose door bumpers and trim with Agnew’s Water Putty. Simply fill the oversized hole with putty, insert the bumper and let set. It may hold better than when originally installed.

General Repair Uses

Use Agnew’s Water Putty to patch cracks and holes in walls, repair furniture, tighten loose wood joints, fill holes in wood so dowels and/ or screws can be reset, fill edges and imperfections in plywood, and repair all kinds of antiques.

Floor Levelling

Ideal for levelling floors or ramping for minor floor level variations. Can be used on concrete, timber and ceramic tile substrates.

Patch Cracked Plaster Walls

Use a putty knife to spread Agnew’s into cracks and cavities of plaster walls. Agnew’s Water Putty does not shrink so the cracks disappear. Plus, your Agnew’s Putty repair will last and last.



Filling knot/nail holes, oversized screw holes, and defects in wood

Ensure that the substrate is sound (no loose floorboards, rotted wood, loose mortar, etc.), free from dirt, oil, dust, flaking paint or other contamination and not impregnated with a sealant. Do not prime first. If already primed, sand and provide some keying. If applying a clear finish, for example the punched nail holes on timber ceiling or wall cladding, minimise the spread and need for excessive sanding by applying a coat first and then fill. Any excess will then easily wipe off.

Add 3 parts filler to 1 part water in a clean vessel and blend into a workable paste. A stiffer mix makes work easier on a vertical surface (lightly dampen surface first). A thinner mix makes work easier on a floor with many defects.

Agnew’s Water Putty can be coloured by adding oxides, dry colour tinters, acrylic paints, etc., however too much can critically retard setting.

Press the filler firmly into the effect and smooth with a putty knife. Slightly over fill and after 30 minutes, scrape level or shape as required. A light wipe of a damp sponge can give a smoother finish.

The filler begins its initial set in about 20-30 minutes and cannot be effectively thinned or worked after this. In 2-3 hours the filled area can be sanded.

Agnew’s Water Putty is not a moisture barrier. If the substrate and/or Water Putty are not dry, moisture can be trapped under impervious finishes or coverings with unsightly or damaging effect. For finishes or coverings that can “breathe” allow 2-3 hours drying time. For impervious finishes allow 24 hours.
