BS 5385 Wall and floor tiling
BS 5385-1:2009 Wall and floor tiling. Design and installation of ceramic, natural stone and mosaic wall tiling in normal internal conditions. Code of practice This part of BS 5385 gives recommendations for the design and installation of ceramic, natural stone and mosaic wall tiling in normal internal conditions; a description of tile types can be found in Annex A. It deals with classes and types of background and their suitability to receive tiling using the following fixing methods.
a) Bedding in cementitious adhesives on an intermediate substrate or as a direct bedding method.
b) Bedding in organic-based adhesive (dispersion or reaction resin) on an intermediate substrate or as a direct bedding method.
c) Bedding in cement:sand mortar on rendering or as a direct bedding method.
Natural stone modular tiles as defined in BS EN 12057 are included within the scope of this British Standard, but natural stone slabs (i.e. units with nominal thickness greater than 12 mm thick) are excluded.
Ceramic tile fittings for corners and edges etc., are less readily available than hitherto, and are now excluded from this British Standard. Specially moulded features, for example trims, are also excluded.
Where the tiling installation needs to meet special functional or environmental requirements, or to assist in counteracting potentially detrimental effects on the installation and/or the structure, see BS 5385-4. The special conditions dealt with in BS 5385-4, for example, swimming pools, shower areas, etc., are listed in Annex B. Agglomerated stone tiles and slabs are not included within the scope of this British Standard. Dimensionally similar to natural stone tiles, they possess different physical and chemical characteristics as a result of the various natural stone, mineral and binder constituents from which they are manufactured.
NOTE 1 Agglomerated stone tiles and slabs are natural stone and/or mineral fragments set in a binder subsequently cut to form tiles with a surface that is normally ground and polished to fi nish. Metal, plastic, resin or mirror tiles and glass tiles of similar construction are not included within the scope of this British Standard, as these require different techniques, adhesives etc., to traditional tiles.
NOTE 2 Mirror tiles are tiles manufactured from fl oat or plate glass with an applied backing.
For the purposes of this British Standard “normal conditions” means normal environmental temperatures and humidity. However, it is not to be inferred from this that all recommendations made in this British Standard are unsuitable for more extreme conditions. Manufacturers’ instructions contain limitations of their products.
BS 5385-2:2006 Wall and floor tiling. Design and installation of external ceramic and mosaic wall tiling in normal conditions. Code of practice This part of BS 5385 gives recommendations for the design and installation of external ceramic and mosaic wall tiles in normal climatic conditions in the UK. It deals with the types of backgrounds and their suitability to receive tiling using the following fixing methods:
a) bedding in cementitious or organic adhesives on an intermediate substrate or as a direct bedding method;
b) bedding mosaics in cement:sand mortar on rendering or as a direct bedding method.
NOTE Cement:sand mortar is seldom used as the bed for external wall tiling but, if needed, see BS 5385-1.
BS 5385-3:2007 Wall and floor tiling. Design and installation of internal and external ceramic floor tiles and mosaics in normal conditions. Code of practice
This part of BS 5385 gives recommendations for the design, installation and maintenance of floor tiling using ceramic tiles and mosaics bedded on concrete, cement:sand screeds, timber, asphalt and existing hard floor finishes in normal conditions. For special conditions see BS 5385-4.
The following flooring materials are not included: natural stone (granite, slate, marble, etc.) tiles and slabs of terrazzo, and composition blocks (see BS 5385-5).
Individual floor tiles with a maximum facial surface area greater than 0.72 m2 and with length to width ratio exceeding 2:1, might require special bedding procedures in accordance with advice from tile or adhesive manufacturers.
Tile fittings for use as skirting, step treads and channels are given in Annex A.
NOTE Where the floor tiling installation needs to meet specific functional or environmental requirements, or to assist in counteracting potentially detrimental effects on the installation and/or the structure, see BS 5385-4.
The special conditions described in BS 5385-4, for example, swimming pools, shower areas, etc., are given in Annex B.
Recommendations for the design and laying of levelling screeds are given in Annex C. Reference is made to tiles bedded directly to a concrete base, but for the design and construction of concrete bases see BS 8204-1.
Annex D contains a recommended method for assessing levels and surface regularity and Annex E is an informative annex providing guidance on the reduction of slip hazards.
BS 5385-4:2009 Wall and floor tiling. Design and installation of ceramic and mosaic tiling in special conditions. Code of practice
This part of BS 5385 gives recommendations for the design considerations and installation of ceramic wall and floor tiling and mosaics in situations where there are special functional or environmental requirements and/or conditions that are potentially detrimental to either the installation or the background or both.
Recommendations are given for the choice of materials, application practices and, where appropriate, for the design of backgrounds and structural bases.
This part of BS 5385 augments the recommendations given in BS 5385‑1, BS 5385-2 and BS 5385-3.
NOTE BS 5385-1, BS 5385-2 and BS 5385-3 give recommendations for internal and external, wall and floor tiling and mosaics for; exchanging information, time schedules, suitable materials, tile backgrounds and bases and their preparation, cement:sand rendering, movement joints, bedding methods for tiles and mosaics, grouting, protection, cleaning and maintenance.
BS 5385-5:2009 Wall and floor tiling. Design and installation of terazzo, natural stone and agglomerated stone tile and slab flooring. Code of practice
This part of BS 5385 gives recommendations for the design and installation of terrazzo tile and slab and natural stone internal and external floorings, and contains recommendations covering the laying of agglomerated stone, a cast manufactured item containing natural stone that is subsequently sawn to size.
The types of bedding methods that can be used and their suitability are given; as well as recommendations for the protection, cleaning and maintenance of the finished floor surface.
