How to use Acrystone® recovery kit?

How to use the Acrystone® Recovery KIT, the solution to repair light scratches on one of our mineral-filled shower trays.
The kit contains a jar with a recovery product, a jar with a catalyst product, a container and applicator roll set, gloves, a mixing cup, a stick, a scouring pad and the instruction manual with the steps to follow:
1️⃣ Clean and degrease the surface of the dish thoroughly until all traces of dust are removed. We recommend the use of acetone.
2️⃣ Shake the repairer bottle vigorously to homogenise.
3️⃣ Pour the catalyst bottle into the recovery can and homogenise the mixture.
4️⃣ Place the resulting mixture into the container provided. Soak the rolling pin in the mixture and drain it in the tray so that it does not drip.
5️⃣ Apply a first thin layer in continuous, even and uninterrupted strokes over the entire tray, in one direction only. Without waiting for it to dry, apply a second coat in the same way but in the opposite direction (cross coats)
6️⃣ When the surface has been uniformly soaked, discard the remaining solution.
7️⃣ Leave the product to act for 48 to 72 hours before using the plate.
