What does a wall mean to you
Are plaster rails for you plaster on rails? Here you can find out why you need plaster profiles for all interior and exterior plastering work. You also get an overview of which profiles you are using for which plaster.
What are plaster rails?
Plaster rails, also called plaster profiles, make it easier for you to plaster indoors and outdoors. They have the shape of rails and are made of expanded metal, wire mesh and perforated metal strip made of different materials.No exterior or interior plaster can do without these plaster rails. They give the surface a clean finish and enable straight edges and stable corners.
Plaster rails are profiles for interior and exterior plasters.After plastering, you can't see anything of them - except for those with a smooth PVC edge. Because it must be visible after plastering.
Why plaster rails?
Plaster protects the facade and is an important design element of buildings. Edges give the building clear lines and character. It is all the more important that these edges are perfectly implemented and plastered. You can do this relatively easily with plaster rails. They also give the house stability and protect it from mechanical loads.
So you need plaster rails when you plaster your facade, plaster the base of your house, plaster your interior wall, plaster the window or door reveal or do plastering work in other areas of your house.
Plaster rails for inside and outside
In outdoor areas, in bathrooms, in the kitchen or in rooms near the ground, the plaster and plaster profile are exposed to increased moisture. Here it is important to use plaster rails made of a corrosion-resistant material, e.g. B. made of stainless steel. With galvanized rails there is a risk that they can corrode, rust and cause damage in connection with materials containing synthetic resin.
For finishing plasters made of synthetic resin, silicone resin or silicate plasters on mineral substrates, galvanized profiles must also be protected with a quartz-filled, organically bound plaster primer (undiluted).
Interior plasterWith interior plasters, the profile edge must remain visible or be covered with plaster, depending on the specifications (single-layer or two-layer plaster).
Always follow the manufacturer's instructions.
For finishing plasters with a grain thickness of <3mm, the finishing plaster must be processed in such a way that the profile edge of the plaster rail is covered and can no longer be seen. Stainless steel profiles or profiles with a coating are best suited for exterior plasters. Galvanized profiles with a coating or aluminum plaster rails with a coating must be covered at least as thick as the mortar slurry. The covering in grain thickness is even better. Again, follow the manufacturer's instructions.
Under no circumstances may galvanized profiles with a smooth PVC edge be plastered over in the edge area. Therefore, clean them immediately after plastering, before the plaster has dried and is difficult to remove.
Which plaster rails do I need for what?
Select the material of the plaster rails
Do you want to know which plaster rail you need for your project? The selection of the material for your plaster profiles depends on the one hand on the plaster chosen and on the other hand on the use of the plaster rail. The following table gives you an overview of which materials are suitable for inside and outside as well as for which plasters and mortars. If you use unsuitable rails, they can rust and damage the plaster and thus also the building.
