Water repellent for external masonry and injection dampcourse systems.

REISOL 69/60WS is a poly-oxo aluminium stearate which may be represented by the formula (0=AL-X)n' Where X is the stearate radical. REISOL 69/60WS is a solution of the product in white spirit which is diluted
with further solvent for application (see below for recommended dilution rates).

Although REISOL 69/60WS is not based on silicones, never the less when the tests
specified for Class "A","B" and "C" silicone water repellents in British
Standard 3826:1969, are applied to REISOL 69/60WS the results obtained correspond to
those specified in the standard.

AGREMENT CERTIFCIATES
 The British Board of Agrement has issued certificate No 79/627 relating to REISOL 69/60WS for use as a transparent water repellent treatment for external masonry and certificate No 81/873 relating to the REISOL 69/60WS dpc system. Packages containing REISOL 69/60WS carry the certificate number and are
marked with the British Board of Agrement logotype.

PHYSICAL PROPERTIES
 REISOL 69/60WS is a solution of polyoxo aluminium stearate in white spirit. It is free flowing liquid at temperatures above 10^oC,but at lower temperatures it tends to set to a soft paste.
 

Aluminium content	5.3oC    0.1%
Specific gravity at 25oC	approX 0.9
Viscosity at 25oC	approX 0.3 poise
Flash point (closed cup)	39oC minimum

SURFACE WATER REPELLENT FOR MASONRY
 REISOL 69/60WS Should be diluted with seven parts by volume of white spirit or any similar non-polar solvent and must be liberally applied to the dry porous surface of the masonry. The solution is usually applied with pneumatic spray apparatus, but small areas can be adequately treated with a large paint brush.

 The area covered depends entirely upon the porosity of the surface and varies between 2 and 4m²/litre. The solution is quickly absorbed into the surface,
and the water repellent effect will extend well below the surface of the substrate.
The depth of the penetration in the case of relatively porous material,can be as much as 0.5cm.

 The full water repellency is produced immediately all the solvent has evaporated, no intermediate curing or ageing is required.

 If the masonry to be treated is wet, or has a non-porous surface, the REISOL 69/60WS solution may not be absorbed, resulting in white staining. The absorbency of the surface can be checked by treating a small test area and if doubt exists about the receptivity of the surface, it is recommended that advice should be sought before the treatment is commenced.

 REISOL 69/60WS should be applied to clean, dry surfaces and will normally not cause any significant change in the appearance of the surface to be treated.
In certain cases, however,as with other water repellents, the nature of the substrate may result in the treated area appearing to be slightly darker.
This is usually considered insignificant but can easily be checked by a trial treatment of a small area. The REISOL 69/60WS coating itself is virtually colourless, and the effect is an optical one due to decreased light diffraction.
The rapid shedding of water by REISOL 69/60WS treated walls results in the maintaining of a clean appearance for much longer than would otherwise be the case.

 * Reduction in porosity *
 The REISOL 69/60WS treament renders a surface water repellent but does not seal it, although the vapour permeability of the substrate is slightly lowered, a treated surface will stil allow the passage of air and water vapour.

 * Resistance to water under pressure *
 Because the REISOL 69/60WS treatment produces water repellency rather than a complete sealing of a surface, it will not prevent the penetration of water at pressures in excess of about 1.4Kg cm² (20 lb/square inch).     

 * Substrates *
 REISOL 69/60WS is suitable for use on the following substrates:

Cement/lime/sand finishes
roughcast or pebble - dash
weathered asbestos cement sheets
weathered concrete
brickwork (excludng denseor semi-glazed engineering bricks)
natural stone
artificial stone
 
 * Durability considerations *
 Compounds based on aluminium stearate have been used for many years for masonry waterproofing and have been recognised as retaining their effectiveness for period of up to 10years (Buiding Research Station Digest No 90,July 1956,page 3) REISOL 69/60WS can be regarded as an anhydrous form of aluminium stearate.

 The results of long term weathering tests are given in the following table, which % shows reduction in water absorption. This figure is obtained by comparing in a standard test, the water absorbed by a treated and an untreated brick.

 If A represents the weight of water absorbed by an untreated brick and B the weight absorbed by an identical treated brick, the effectiveness of the treatment can be expressed as follows:

 

(A  -  B)X 100	=Percentage reduction in water absorption
A

   Percentage reduction in water absorption

Test material	Initially	1Years	2Years	3Years	4Years
Standard brick	99.6	99.5	99.2	98.6	97.5
Bath Stone	99.8	99.0	98.9	97.4	93.6
Portland Stone	99.2	96.1	97.7	84.0	38.6

 Tests indicate that portland Stone has a higher alkalinity than Bath Stone, and this may account for the considerable reduction in the proofing of the former.
Despite this high alkalinity the figures above show that some measure of proofing remains even after for Years.

 In order to establish the long term durability of REISOL 69/60WS a test wall was erected in 1965.The wall consisted of sections of three types of brick and two types of limestone. It was divided vertically into two equal sections, one of which is treated with REISOL 69/60WS and the other untreated.

 Annual testing was carried out by an independent authority and after ten years exposure the REISOL 69/60WS treated section still showed no sign of allowing water penetration and was less affected by atmospheric pollution than the untreated portion.

* Internal surfaces  *
 Internal walls subject to damp patches have been successfully treated and the dampness prevented from striking through.This type of surface has been satisfactorily wallpapered.These surfaces have also been painted with conventional oil paints, but some emulsion paints do not soread satisfactorily.

INJECTION DAMPCOURSE SYSTEMS
 For this application we recommend a solution of REISOL 69/60WS in white spirit containing 0.4% aluminium; since REISOL 69/60WS contains 5.3% aluminium,this works out to a dilution of 1 part REISOL 69/60WS to 12.25 parts of white spirit(by weight).
It was for such a solution that Manchem was awarded Agrement Certificate 81/873.

 To determine the aluminium content of both REISOL 69/60WS and dpc solutions we recommend the use of the DCTA analytical method given in BCDA publication TIC4.

 The Agrement Certificate 81/873 for REISOL 69/60WS dpc should be consulted for installation details.

STORAGE AND HANDLING
 REISOL 69/60WS is essentially a solution in white spirit of a poly-oxo aluminium stearate compound.It is flammable liquid and should be stored and handled accordingly
For shipping purposes it is classified as a flammable liquid since it has a flash point between 73^oF (23^oC) and 141^oF (61^oC)

 REISOL 69/60WS deteriorates when exposed to the atmosphere due to reaction with moisture, containers should therefore be kept sealed and once opened, should be used as quickly as possible.

 The dilutions in white spirit of REISOL 69/60WS which we recommend for masonry water repellent and dpc applications, are much less sensitive to water, and will not thicken appreciably when exposed to the atmosphere for up to 8 hours under normal site conditions.

 However for long term storage it is still essential to avoid water contamination and to ensure that containers are tightly sealed.

 Although the toxicity of REISOL 69/60WS had not been determined, to the best of our knowledge this product does not constitute a health hazard if handled in the proper manner. However, inhalation, ingestion and skin and eye contact should be avoided. It is therefore advisable to wear gloves, protective clothing and goggles when handling REISOL 69/60WS .

 A Material Safety Data Sheet is available for REISOL 69/60WS and users are recommended to refer to it before starting work with this product.
