The maximum weight of tiling which can be supported by a dry,
well-adhered plaster background is 20kg/m². This is equivalent to
ceramic tiles with a maximum thickness of 8mm plus tile adhesive or
natural stone tiles with a maximum thickness of 7mm plus tile adhesive
The weight of tiling to a plasterboard background direct
(without plaster skim) should not exceed 32kg/m². This is equivalent to a
ceramic tile and adhesive with a maximum thickness of 12.
Porcelain tilesare ceramic tiles with a
water absorption rate of less than 0.5 percent that are used to cover
floors and walls. They can either be unglazed or glazed.
Large-scale production of porcelain tile is
undertaken in many countries, with the major producers being China,
Italy, Spain and Turkey. There are also countries undertaking
small-scale production, such as Australia and strong growth in
The hardness of the tile can be rated from zero to
five according to ISO 10545-7 (also, ASTM C1027) test for surface
abrasion resistance of glazed tile, and this can be used to determine
suitability for various end use conditions.
| Sub-floors solid or wood need to be dry. British Standards state a
screed should be tested using Hygrometry as described in annex A in the
standards. The maximum level of relative humidity in the screed is 75%.
There are many manufacturers of moisture testing equipment such as
Tramex and Protimeter whose instruments can be used to identify areas
for further testing with a hygrometer. These instruments can also be
used to check the relative humidity to British Standards. The duration
of the test will depend on the sub-straight.|
Tanking all wet areas prior to tiling is essential.
Tiling onto a wooden floor is a big no no , because it can cause your new tiles to crack with the natural movement and expansion you get with wood, The following over boarding should be used to decouple the tiles from the movement ...
