out of the joints of the brick work etc., plus thorough washing and sluring.
Slurry is made with 1 part of to 2 parts of water mixed with cement to creamy consistency.
(iii) Floor Toppings
It consists of cement either with
lGranite : The Granite aggregate should consist of 10 mm (3/8") material graded down to fines.
lSand : Really coarse and gritty washed sand with both aggregates, a mix of 2:5 is advised.
4 litres of must be used with 100 kg (2 Bags) of cement. This is roughly equivalent to gauging with a mixture of 1 part of to 4 parts of water.
UNDER NO CIRCUMSTANCES MUST FLOOR TOPPING BE LAID TOO WET OR TROWELLED EXCESSIVELY.
The following general directions should be observed :
(1) Render the toppings smooth with a wood float and when the set commences, bring to smooth finish with a steel trowel. It is bad practise to break the set of the cement by wetting and trowelling after too long an interval.
(2) At a proper consistency, no water should rise to the face. If this occurs, it must NOT be sprinkled with neat cement.
(3) Mature the topping wet, by keeping covered with wet sacks of saw dust, or by watering at intervals for five or six days.
lWhere concrete is more than three days old, it is essential that the surface be -
(a) Close hacked or otherwise roughened.
(b) Thoroughly washed free of dust.
(c) Slurried with cement
Rapid hardening of mass concrete and renderings :
(i) Undiluted mixed with neat cement produces a hard set in two or three minutes where fast setting is required.
(ii) Mortar mixed with diluted with an equal amount of water sets in about ten minutes and must be used within that time.
(iii) Floor repairs - 1 part of with 2 parts of water normally provides sufficient acceleration as is also the case when 4 litres of is used per 100 kg (2 bags) of

cement of concrete mixed stiff.
The given figures can only be rough approximation, as the hardening time of cement is dependent upon the prevailing temperatures, the make and freshness of the cement, the amount of water used, the proportion of cement and the suction in the background. Thus in quantity sufficient to half the setting time of concrete during the summer, may only suffice to maintain ordinary setting times during cold weather. One or two trials are required under the actual conditions involved.

Concrete Hardening and Waterproofing Liquid is made available in 5 lt. and 30 lt. Jerry cans, which are made of hard durable HDPE material which is not only non-reactive with
but enhances the storage stability and also preserves it, making it reusable at intervals when needed.
