Step 1

In a clean container add 4,6-4,7 litres of clean water and gradually empty the content of the bag while mixing continuously, in order to produce a homogenous mass of mortar. Leave the mixture to mature for 3 min and mix again briefly.

Step 2

During the application you must also mix gradually.

Step 3

After the preparation of the mixture do not add additional water to correct the workability of the mortar. This shall lead to a decrease of resistances and to the increase of its shrinkage.

Step 4

WRM 512 is applied like common plaster or common masonry mortar.

Step 5

For plaster application: It is normally rubbed with a spongy flute. Note that the waiting time for rubbing varies with temperature, substrate absorbency and mixing water ratio.

Step 6

Apply the first coat of plaster using the repair mortar WRM 512, taking care to bring the repainting plasters back into contact with the existing masonry and old plaster surfaces.

Step 7

Where necessary, insist on the trowel to ensure better contact.

Step 8

Next, when the first coat is coat, the final coat of plaster is followed by WRM 512 repair mortar.

Step 9

When pulling and the final layer is passed through the bar, then if it is it is necessary to smooth it with a bit. Technic al

Step 10

Substrates of heat-insulating panels (eg polystyrene slabs, etc.), such as columns, beams, etc., are recommended to reinforce WRM 512 with glass mesh to prevent cracks. The glass mesh is placed in the following way: A first coat of plaster is applied and while still fresh, the glass strip is pressed gently to become the same with plaster.

Step 11

Then a second and final coat is applied. The purpose is that the grid is fully integrated with WRM 512 and is located at 1/3 of the thickness of the plaster from the outside to the inside. Finally, the mesh should also cover the area on both sides of the thermal insulation plates by 10-15 cm.
