ROUGH CONCRETE look
For those looking for a modern and durable finish, a rough concrete surface is a great choice. This type of plaster resists the weather very well, making it an ideal choice for outdoor surfaces. It also has the advantage of being able to mask minor irregularities and imperfections in the substrate. This will give you a modern and perfect look for your exterior.

Use a stainless steel trowel to apply plaster with a grain size of 2.5 mm in one direction.

Use a plastic trowel to make grooves in the plaster.

TIP: For a more pronounced effect, perform strokes in different directions.

If the plaster no longer adheres easily to the stainless steel spatula, smooth it out.

Paint the plaster with a decorative varnish after drying.

Before the varnish dries, wash it off with a wet sponge.

TIP: Wash off the paint to achieve a true concrete look.
