Close containers after use.

Seal porous mold surfaces first (ebalta mold sealer).

For optimum mold releasing we recommend a special release agent (like T1-1), which can be applied easily with a brush or be sprayed. Releasing of the mold 2-3 times, evaporate for about 20 min. after each releasing.

Mixing ratio resin/hardener according to instructions.

Stirring rods etc. with residual resin can be easily cleaned with ebaclean.
