I followed the instructions that came with the spartite.
It pours easy and is self leveling. Short pot life. Max 10 minutes..
I put tape around the edge of the partners so the hardened spartite is over the top edge of the partners and should be watertight there.
After lining up the mast with short wedges, I built a dam from below with supplied foam rolls and modeling clay. Then I poured the fluid spartite between mast and partners up til the wedges. Let that harden up. 24 hours later I removed the wedges and made the final pour.
Total height of the spartite wedge is 7,5-8 cm.
the Weicon 85 was not as fluid and more difficult the use. Not such good self leveling properties, but longer pot life to work it in place.
