Determination of the individual levels of slip gluing can be done with the help of a masonry cord, a traditional leveler or a laser level.
The surface area covered by the adhesive should be adjusted to the air temperature so as not to allow it to dry. The adhesive should be fresh and moist. If the adhesive dries too fast, we can use a spray to dampen the surface of the adhesive. We can also spray a surface of the adhesive in the bucket.
The slips are much more comfortable to cut than fold. The brick slips are made almost entirely of natural materials, not of "rubber", and these have a limited stretch. By cutting the slips we can finish one wall completely and then return to the second surface. In case of bending, we have glue immediately on both surfaces and you need to remove it from one of them before it dries and then reapply. And it takes a lot of time. When the adhesive is dry, add the adhesive to the substrate after the adhesive is dry (the material from which the slip is made). We suggest bending to the interior where the details are very important and the pace of work may be smaller.
Ensure that the entire surface of the slip adheres well to the glued wall so that there is no void beneath it.
Remember that the smoothed adhesive tightly covers the edges of the slips so that no water gets in.
