How to prepare?


This product is specially designed to be applicated with projection machinery.

It's recommended to adjust the machine in a 25% mortar/water relation and modify this relation until getting the paste density wanted.

The mortar/water relation may change depending on working conditions.

In case of hand application, mix in a 6-7 water litres bowl per each 25 mortar kgs.

How to use?

Project the mortar on the wall.

The water volume must be graduated to get a paste density with no slipping-off.

Once projected, mortar must be smoothed with a trowel, trying that all the surface is covered and eliminating at once possible air bags.

Resultant coat width must be between 5 and 8 mm.

Fix the fiberglass or rockwool panels through manual pression.

Fix the panels during the "open time" (20 minutes).

Out of this time, its properties are reduced.
