HOW TO USE IT:
Mixing
TopCoat 2-1 is mixed at a 2 parts resin to 1 part hardener by volume or weight. The mixing ratio must be accurately followed. It is not possible to change the ratio as this would result in lower mechanical properties and the resin not curing properly. Mix by hand. Regularly scrape the sides, base, and corners of the mixing vessel to ensure full homogeneity. Mix until it is a uniform colour & consistency (usually 3-4 mins).
The resin component has a purplish colour in the bottle, this is the strong UV inhibitor and will not be visible in a thin layer.
Application
Apply by hand pouring or brush/roller. The resin can be tinted any colour with the addition of polymer pigments available in solid and translucent colours.
Eli-Chem’s resi-TINT Acrylic Inks and resi-TINT MAX range are ideal.

LEVEL: Ensure your piece is perfectly flat and level, otherwise the resin will run to the lowest point and pool in the centre, leaving too little resin at the corners. On large canvas paintings / pictures you should tighten the canvas as much as possible or place a board underneath to support it uniformly.
BUBBLES: Any bubbles created by hand mixing can be easily popped by using a sharp object or by passing warm air over the surface of the resin with a blowtorch or hot air dryer on slow speed settings. Do not hold closer than 30cm to your artwork otherwise you risk creating ripples and dimples in the resin finish. If you use alcohol inks DO NOT use a flame to remove the bubbles, as alcohol is flammable.
DUST: You will need to protect the piece from dust accumulation for at least 12-24 hours. You can do this by using a raised cover or box to cover the piece.
