| Well,
the resin mix was a disaster. It set after 24 Hrs with a 10mm hard
crust but was still soft in the middle. I didn't want to increase the
amount of resin in the mix as it looses that inert feel when you rap
it, so I scooped it all out and cleaned up the top plate and mould box
with Acetone. I will revert to a tried and tested technique and cast it
in concrete. Coated the already Polyester coated underside with PVA and
let it dry. Gave it a second coat of PVA and while this was still wet
poured and tamped the concrete. The concrete was made up of 3 parts
Horticultural grit (4 to 5mm), 2 parts sharp sand to 1 cement, I kept
the mixture fairly dry. I also mixed up some mortar using just the
sharp sand, this was pushed into the small spaces, corners etc where
the gravel would not fit, it was all tamped down
together. PVA was also added to the metering water of the mortar
and concrete. |
