Some wall tile glazes, particularly
the more specialised effects used to create surface features and strong colours, are subject to crazing. This aspect is an
inherent characteristic of the glazes and may occur after fixing but will not affect the performance of the tiles.
Non-spacer tiles should be spaced
by the use of readily available spacer pegs. It is recommended that proprietary tile edging trims are used for all external
corners and exposed tiling edges.
Specialist Fixing (Installation)
The Minton Hollins ‘Studio Collection’ is a range of ceramic
glazed wall tiles that have been designed to replicate the appearance of
an authentic handmade tile. Given this, the variation in shade and crazing are deliberate factors which contribute to the
overall appearance of the finished product and could vary
from batch to batch. Due to this fact these tiles are susceptible to crazing prior to,
during and/or after installation and can not be covered by the regular crazing/staining standards. Johnson Tiles can not accept
responsibility for any complaints associated with staining/crazing.For the best results we advise that they are installed by a professional fixer.
In any instance we suggest
the use of pre-grouting sealer prior to grouting and an impregnating sealer once the tiles have been fixed.
It is recommended that all
cuts are carried out using a ‘wet’ diamond-wheel cutter (as the use of rail-cutter could result in ‘chattered’
This particular glaze system can
be vulnerable to prolonged contact with certain proprietary commodities of an acidic nature, examples of which include particular brands of hair products, cleaning
agents, red wine, beetroot juice, etc; of which overnight contact could
lead to permanent discolouration.
N.B. Please note that tiles within
this range must be sealed with an appropriate sealer i.e. ‘Aqua Mix Sealers Choice 15 – Gold’ or equivalent
Bullnose (Round-Edge) Tiles
Prismatics, Formations Minton
Hollins and Spirit all come with a glazed Finishing Strip and/or plain or decorated bullnose to match the associated field tile.All the company’s wall field tiles, do not have fully glazed edges, which makes grouting easier.
Care should be taken during installation
and grouting to avoid damage. Abrasive cleaners and strong chemicals, which may harm the decoration, should not be used.
Glass Wall Tile Borders
This decorative ranges include
glass wall tile borders manufactured from Tempered Glass. They are designed to be used in conjunction with ceramic tiles.
Details for fixing and cutting these products are given on the product cartons.
If coloured grouts are used then
the manufacturer's instructions for use should be carefully followed. A trial area should be grouted before proceeding with
the whole tiled area to check whether any staining of the tiles occurs. Johnson Tiles accepts no liability for staining or
damage to tile surfaces incurred during grouting of the tiles. Generally, the use of such grouts is not recommended with satin
or matt glazed products.
Grouting and Cleaning
Care should be taken during installation,
particularly when grouting, to avoid scratching the glazed surface. Abrasive cleansers and strong chemicals that may harm
the decoration should not be used. The Formations scored products
are intended to be fully grouted. It is particularly important for tiling which will be subject to wet applications such as
showers for the scoring to be grouted.
Slight variation in overall size
and shade of floor tiles occurs during the manufacturing process. Where possible, sufficient tiles for the area to be covered
should be obtained in one consignment to ensure that a supply of compatible sizes and shades is achieved.
Only porcelain floor tiles may
be suitable for certain external situations. Please check the suitability before installing any floor tiles in areas subject
The correct floor tile adhesive
and grout suitable for the installation must be used.
Large Format Wall
The large format wall tiles require
spacing by the use of proprietary tile spacers. Nominal joint widths of 2 to 3 mm are recommended to ensure that the modular
co-ordination is maintained.It is recommended that proprietary edging trims
are used for external right angle detailing. Johnson Tiles large
format wall tiles can be fixed to a variety of background types. All backgrounds must be dry, flat and free from surface contamination.
New backgrounds must have been allowed to dry for the appropriate length of time prior to the commencement of tiling. The
background should be sufficiently strong and rigid to support the weight of the new tile work. Friable or weak backgrounds
should be made good prior to tiling. Appropriate advice as to the suitability
of walls in respect of tiling should be sought from a qualified person before commencing tiling. This is particularly important
if the new tile work is over existing tiling.
It is important that an appropriate
adhesive is used which suits the particular wall background and service conditions. Johnson recommends that water resistant
adhesives are used for wet areas and grouted with a water impervious grout.
Format Wall Tiles- Cutting
The high quality white body of
the Johnson large format wall tiles can be cut, shaped and drilled in the same manner as the smaller format wall tiles. The
use of a heavier gauge floor tile cutting tool is used to facilitate the cutting process due to the thicker gauge of the wall
tile body. For intricate shaping and cutting Johnson recommend the use of a wet
diamond wheel cutting machine.
Large Format Wall
Large format wall tiles are heavy
and particular care should be taken when lifting and handling the tiles to avoid injury. Any carton banding used to stabilise
the cartons whilst in transit should be removed prior to lifting and opening the cartons. The transit banding should not be
used to lift the cartons.
