|That's the first plinth poured, I will give it a few hours drying and then polish the top with a float.
When filling the mould I mixed a small amount of sand and cement and applied this first around edges and corners and of course the base of the inserts, to make sure the detail was picked up, then the concrete mix was poured in and tamped down and levelled. Both were a strong mix and had PVA added to the metering water. PVA was applied neat to the inserts and spacers the night before and left to dry, a second coat was applied half an hour prior to adding the mortar/concrete, which will aid bonding. The mould had two coats of Danish Oil applied to seal the timber and a generous coating of furniture wax was rubbed over the internal surfaces as a mould release prior to casting.
