Instructions for Use

The material is applied in 2 layers. Each layer requires approximately the same amount of material.
We do not recommend mixing more than 2.5kg of Concrete Effect at once, as the material thickens quickly. Processing Time: approx. 30min.
Mix the CONCRETE EFFECT Powder with water in a 5:2 mixing ratio (e.g. 2.5kg Powder with 1L water).
Colour the material by adding approx. 2% WB Pigment to it.
Apply a thin layer of the material using a trowel.
Wait approximately 30 minutes before applying the second layer.
Mix fresh material again and use both trowels to dab it onto the surface until it is fully textured.
Smooth the texture using a clean trowel with light pressure. Move the trowel from top to bottom.
Finally, lightly dab the surface with a bristly brush to create additional texture.

I first trie on a small piece of wood as I never used any plaster before and after a few tries i got a hand of it. You can see the final result on my picture :)

The first time, I mixed too much material at once and had to rush a little. After that, I worked with smaller quantities and the process became much more manageable. The 30-minute window is sufficient as long as you’re not working on too large an area at once. In the end, I was very pleased with the result and would do it again without hesitation.

I’ve been doing this work for several years now, and Rock Design plaster is one of the more enjoyable materials to work with. The large room was quite a job, but the material handles well as long as you don’t mix too much at once, as it thickens quickly. The client was immediately enthusiastic when they saw the first walls. You do need to be patient with the second coat and the trowel finish, but if you do it properly, it produces a really beautiful texture. The result speaks for itself.

The rocky plaster is a really great product. It helped me create the effect I was looking for. The selection of pigments is also excellent, and I decided to go with Cappuccino. The result is really impressive.
