The selection of which Dry-Treat product is the right one for the
proposed application is determined by the objectives required to be
achieved. The most basic important factors are
 |
Corrosion protection |
|
Water absorption to be prevented or
inhibited |
|
Moisture vapour transmission |
|
No undesirable side effects |
|
Porosity
of the substrate |
|
No change to substrate appearance |
|
Durability period desired |
|
Ease
of application |
|
Economy |
|
Environmental friendliness |
Dense low porosity building materials such as reinforced concrete used in
the construction of rail/road bridges/viaducts, port facilities/maritime
structures and similar heavy infrastructure developments are planned for
long service life. Ultra long-term protection is a necessity, especially
for protection against soluble salts induced corrosion, ASR and other
deteriorative mechanisms, therefore Dry-Treat BHN is the product of
choice.
Dry-Treat BSM 40 is suitable for treating all absorbent mineral
facing materials with the exception of natural stones. This encompasses
all lime and cement bonded media such as gas concrete, mortar, plaster,
bricks, ceramic tiles, grouts, pre-cast concrete architectural façade
panels and similar substrates.
Highly porous building materials such as brickwork, sand lime
brick, mineral render and plasterwork are highly absorbent of silane
materials and the use of solvent free silanes is impractical because of
the large quantities of material absorbed by these media and the high
depth of penetration achieved is mostly unnecessary.
Dry-Treat BSM 100W or Dry-Treat WS 405 are suitable products for this
kind of application being economical and effective choices.

Whilst all Dry-Treat products have an excellent effect on maintaining
surface appearance of substrates and reducing microbiological growth,
dirt build up, efflorescence and other similar surface contaminants,
Dry-Treat has a range of products specifically combining waterproofing
and stain resistant properties.
Dry-Treat
FAS 8800 and 8810 are excellent for this use on concrete and all porous
building materials including natural stones such as limestone and
sandstone, terracotta and similar ceramic materials.
For non-
porous substrates such as granite, marble and glazed ceramics, Dry-Treat
FAS 8262 and 8263 impart similar properties and are excellent for
maintaining the appearance of the substrate against the ravages of
environmental weathering.
With these
products and FAS 8261, there are also specialist applications for other
industries involved in protection of totally non-porous materials such as
metals, glass and other smooth substrates.
All
Dry-Treat products exhibit no change to the surface appearance of the
treated substrate and render them hydrophobic and stain resistant to
varying extents. For high resistance to staining, use the FAS grades.
For determining the effectiveness of the
application of the Dry-Treat products, a number of methods are used which
assures the asset owner that the specified material has been successfully
installed.
These
vary from on site in-situ testing to laboratory controlled test regimes.
Detailed application specifications for each product clearly
outline the testing required and indicate minimum standards to be
achieved.
Because
no individual project is exactly identical in nature,
customized
specifications reflecting clients’ needs and requirements can be
developed in cooperation and consultation between the clients
representative and Dry-Treat. Contact your local Dry-Treat representative
for further information and assistance. |
