DAMPPROOFING, SEALANTS & ADHESIVES
With the trend for outdoor living on the up, Stuart Ross, technical advisory service supervisor, Building
Adhesives Ltd, advises on the best way to protect external tiles and natural stone from water damage.
In September 2011 a publication by the Royal
Institute of British Architects entitled ‘The
Case for Space’ showed results from a survey,
which indicated that 49% of people moving
home wanted more outdoor space.
This trend for outdoor living via applications
such as balconies, terraces and patios has led to
growth in the domestic market for external tiling
and a wide range of colours, textures and finishes
are currently available. Inside/outside tiling is
preferred over cheaper finishing alternatives,
mainly due to the durability, longevity, lower lifecost
(replacement of materials not usually required
etc.) and for being low maintenance i.e. easier to
clean than many non-tile coverings and structures.
Many types of tile applications are possible
externally, when they are specified with the
correct system assemblies. This includes the use of
finishes such as ceramics, porcelain, some natural
stone and pavers.
