Using Agnew’s water putty as a wood, concrete or plaster filler and more!

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 to say, the punched nail holes on timber ceiling or wall cladding, to minimise the spread and need for excessive sanding you may apply 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 overfill 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.

A longer drying time should be allowed if:

  1. A thinner than 3:1 mix is used;
  2. The defects are deeper than 5mm;
  3. The weather is cold or humid; or
  4. Any retarding agent has been used

Unless coating with a clear finish, prime the filled area before decorating. Water Putty does not absorb stain in the same way as wood. However 2 to 3 coats of stain or colouring the putty to the colour of the stained timber can provide a satisfactory result.

Safety Information

Agnew’s Water Putty is NOT toxic, although if dust is to be created wear a dust mask approved by AS 1716. Water will dilute and wash off any errant unset filler.
