Today I purchased the epoxi resin. My choice is SR 5550*. It is good for composite sea boats. Contains no fenols and amins.

For thickening the gluing surface I’ll use Trecell and Silicell. These work like Wood Fill (substitute Wood Flour and Carbosil).

A chemical engineer of A-P have given me an advice: do not glue under 20 degrees (Celsius) and you have no problem with gluing.

The balance is also important. Difference between the resin and the aggregate is maximum 5 percent.
