Surface Preparation
-
Test patch is recommended
on a new substrate or if the product has not been used before.
-
All surfaces to be clean,
dry, and free of loose material.
-
Thoroughly solvent wipe
wooden surfaces to remove any oily deposits and allow to dry.
-
Method of Application
-
For best results it is
recommended to store , apply, & cure resin in a room with a temperature
of 25 ° C or greater.
-
Coverage for table tops
can be estimated using the 111 “rule” – 1 litre of resin covers 1 sq
metre at 1mm thickness. We generally recommend 2-3 coats.
-
Add 1 part hardener to 1
parts base (by volume) and thoroughly
-
Hand mix small quantities
with a stick taking care to scrape sides & bottom of container then
allow to sit for a few minutes for air to come out - watch pot life.
-
Pour on to surface to be
coated and gently spread with a brush or similar allowing to “drizzle”
over edges.
-
Leave product to self
level then use a gas flame or heat gun (if required) waved gently over
the surface to release any air bubbles.
-
Allow to cure in a dust
free environment
-
The product can be cut and
polished although the finish is usually good enough without this.
-
Cutting & Polishing - wet
sand with 600 then 1200 grit paper until a uniformly flat surface is
achieved. Buff with 3M 5958 cutting compound (or equivalent) until level
of gloss required is achieved. A coat of 3M Perfect-It III polish (or
equivalent such a Diamond Cutting Compound 2.0) can be applied to give a
very high gloss finish.
-
Note: GEMCOAT ES 1:1 is
not recommended for deep pours – use GEMCOAT ES 2:1 LV
