Sand 0,8mm

Dry sand in bucket

Manual

Carry out an adherent sandblasting on the fresh resin, by manually projecting the dry sand at a rate of 3 to 4 kg / m². Use studded shoes that allow you to walk on the resin. The sand should cover the entire surface and have a dry appearance (not coated with resin). Leave to polymerize for 24 hours. Then, remove the loose sand by brushing and vacuuming with an industrial vacuum cleaner. The sand used as an adhesion bond must be dry uncoated, perfectly adherent and encrusted with the primer.
