the following are generic guidelines.Residential Commercial IndustrialPVC PVC -Aluminium Aluminium -Anodised aluminium Anodised aluminium -Brass Brass BrassStainless steel* Stainless steel* Stainless steel** Generally suppliers offer profiles and trims in grade 304 and grade 316 stainless steeloptions. The selection of the different grades will depend on the application and exposure tochemicals.Material properties:Stainless steel can sustain high mechanical stresses and is especially suited for applicationsrequiring resistance against chemicals and acids, e.g. swimming pools, hospitals and foodindustry applications. All cleaning agents should be free of hydrochloric and hydrofluoric acid.Stainless steel profiles are offered in various grades providing chemical resistance againstcommon substances that are encountered in tiled environments. Whilst stainless steel isresistant to a variety of chemical substances it does not negate the need to employ a cleaningregime for the profile(s).Areas ofuseGrade304Grade316Domestic Commercial SwimmingPoolsExternal ChemicalResistanceFoodIndustryMedicalIndustry x x x x The above chart is a generic guide to the use of stainless steel profile grades in tileinstallations; verify individual suitability with the supplier.Brass can sustain high mechanical stresses and is resistant to some chemical exposure. Incontact with air, solid brass will oxidize and develop a natural patina. This oxidation can becleaned with a suitable polishing agent.Aluminium profiles should be verified for their suitability in the environment they are to beused. Aluminium is sensitive to alkaline substances, which may result if the formation ofcorrosion products (aluminium hydroxide). As cementitious materials in conjunction withmoisture become alkaline it is important to solidly bed the profiles and ensure all adhesiveand grout residue is removed from the profile. Oxidation films can be removed with acommon polishing agent.PVC profiles should be checked with the manufacturer for suitability and chemical resistance.Wall profilesThe manufacture of ceramic tiles with glazed edges is not common these days. Theconsequence being the body of the tile is visible at external corners or where tile edges arevisible at the edges of skirting or transitions to other coverings.The basic purpose of wall trim profiles is to provide a decorative edge whilst protecting the tileedge from damage.A variety of materials, colours and surface finishes are available offering increased designflexibility to provide protection to the exposed edges and create beautiful design features for adurable installation.TTA Technical advice note 10 – Tile Trim Profiles© The Tile Association 2013
Trim profiles are usually available for most applications and include edge protection anddecoration profiles in square and rounded formats, with other options being available fromindividual manufacturers.Square Edge Trim Round Edge Trim Cube Shaped TrimInstallation (generic installation guidelines for profile with anchoringlegs):• Select the profile according to the tile thickness.• Using an appropriate notched trowel, apply tile adhesive to the area where theprofile is to be placed. If using the profile on an external wall corner, tile one wallfirst, then trowel tile adhesive over the corner of the second wall.• Press the anchoring leg into the fresh adhesive and align.• Trowel additional tile adhesive over the anchoring leg to ensure full coverage andsupport of the tile edges.• Solidly bed the tiles over the anchoring leg, so that the top of the tile is eitherflush with the top of the profile or up to 1 mm lower.• Set the tile to leave a grout joint of approximately 1.5 - 3 mm.• Fill the joint completely with grout material and remove any residual from thevisible surfaces of the profile.To overcome the need to mitre profiles at internal and external corners, a large number ofsuppliers provide corner pieces to compliment the trim profile being used. The corner piecescan enhance the finished application and speed the installation process. Consult individualsuppliers on what is offered.Floor profilesCeramic and stone tiles are inherently brittle by nature; therefore their exposed edges canchip or crack if left unprotected. Transitions between floor surfaces and at thresholds areparticularly vulnerable to damage. There are a wide variety of profiles and trims available toprovide edge protection and transitions at thresholds and between adjacent surfaces,resulting in durable, maintenance free tiled coverings.The profiles can be generally grouped into two categories, transitions between same heightsurfaces and transitions between different height surfaces.Selection of the appropriate transition profile will be determined on individual applications,taking account of the environment and traffic conditions, etc.When selecting transition profiles careful consideration should be given to the exposure of theprofile to traffic load and chemical exposure. Where residential and light commercialenvironments are encountered the majority of material listed will be suitable, however forhigher traffic loads, brass and stainless steel profiles would be preferable.Where floors are subjected to frequent wetting or have aggressive cleaning regimes, stainlesssteel profiles would be favourable.TTA Technical advice note 10 – Tile Trim Profiles© The Tile Association 2013
