In special cases, the suitability of a proposed type of profile must be verified, based on anticipated chemical, mechanical, and/or other stresses.
Schlüter-DECO-M, in solid brass, is resistant to most chemicals used in tiled environments. Solid brass that is exposed to air will oxidise, resulting in a natural patina. If exposed to moisture or aggressive substances, heavy oxidation and spotting may occur.
Schlüter-DECO-MC is particularly suited for coatings, e.g. to match chrome plated bathroom fixtures. All visible surfaces must be protected against abrasion. Remove mortar or grout residue immediately from visible surfaces.
Schlüter-DECO-E is made of roll formed V2A stainless steel (material no. 1.4301). Stainless steel is particularly suited for applications that, in addition to heavy mechanical stresses, require resistance to chemicals (e.g. exposure to acids, alkalis, oils, greases and solvents). Even stainless steel is not resistant to all chemical stresses, and may be affected by hydrochloric and hydrofluoric acid or certain chloride and brine concentrations. Special anticipated stresses should therefore be verified in advance.
Schlüter-DECO-A, in aluminium, must be tested to verify its suitability if chemical stresses are anticipated. Cementitious materials, in conjunction with moisture, become alkaline. Since aluminium is sensitive to alkaline substances, exposure to the alkali (depending on the concentration and penetration time) may result in corrosion (aluminium hydroxide formation). Therefore, it is important to remove adhesive or grout residue from visible surfaces. In addition, ensure that the profile is solidly embedded in the setting material and that all cavities are filled to prevent the collection of alkaline water.
Schlüter-DECO-AE, made of anodised aluminium, has an anodised surface finish that will not change under normal circumstances. The surface must be protected against abrasion or scratching.
Aluminium is sensitive to alkaline media. Cementitious materials, in conjunction with moisture, become alkaline. Since aluminium is sensitive to alkaline substances, exposure to the alkali (depending on the concentration and duration of exposure) may result in corrosion (aluminium hydroxide formation).
For this reason, remove mortar or grouting material immediately from all visible areas and do not cover freshly installed coverings with foil. In addition, ensure that the profile is solidly embedded in the setting material to prevent water from accumulating in small cavities.
