Putty W™ is a two-component, water-based filler/putty
material comprised of Aqua-Resin L Liquid and Putty W
Powder. It adheres to wood, metal, rigid foam and most
plastics.* It is compatible with chopped fiberglass or
fiberglass mat. It is highly flame resistant.
It is useful as a wood filler and a sculpting material as well
as a replacement for polyester filler putties.
Putty W is permanent in all applications, including exterior
use. For long term applications out of doors, an exterior
sealer or good quality exterior paint is recommended.

Pour a quantity of L Liquid into a disposable container. A
self-cleaning (non-stick) silicone rubber cup is also useful
for this purpose. Add the Putty W Powder while stirring. No

to achieve desired viscosity. Coloring can be achieved
Or if by weight, 100 parts L Liquid to 150 parts Putty W
Powder is a good starting point.
For most applications, a “peanut butter” consistency is the
most useful. Apply with a spatula or putty knife. However,
the mix proportion may be adjusted to give a thinner,
“soupy” mix for wetting through fiberglass mat, or to a
thicker clay-like consistency for plugging large holes or
working over an armature.
Mix until homogeneous; then an additional 30 seconds.
There will be about 10 to 15 minutes working time.
