A fire resistant, light weight cement supplied as a pre-mixed dry
powder for mixing on site with water. This cement is white in colour
for ease of identification and provides up to a 4 hour fire rating in
masonry or concrete block walls and concrete floors when installed
as per the instructions on the bag and on the reverse side of this
data sheet.
INSULATION on the penetrating services will vary depending upon
the services that penetrate the barrier. PROMASTOPB Cement is
fire tested to BS 476: Part 20 and AS 1530: Part 4, with reference
Feature Advantages
Tested in floors and walls.
Economical thin application.
Quick setting.
Non-shrinking.
Readily drilled or penetrated for post installation of services.
Easy to mix to various consistencies.
Hard surface finish.
When mixed with 15 to 19 litres (kg) of clean water, the bag will produce
approximately 25 litres of mix which will fill an area approximately
0.63m2
at 40mm deep or 0.42m2 at 60mm deep.
This equates to approximately 1.6 x 22kg bags per m2 of clear opening
at 40mm deep or 2.4 x 22kg bags at 60mm deep (other usage depths
can be calculated directly from these figures). The final yield will
depend upon the volume of water used. The figures given in this data
sheet are for guidance only.
PROMASTOPB Cement can be mixed to a consistency to suit the
application. For floors, if services are close together, a wetter,
pouring mix is preferable. For walls, it is always preferable to use
a dry, packing mix. The amount of water used will also depend on the
weather conditions at the time, but do not use a ratio of less than 2:1.
The following may be used as a guide:
Pourable mix: 1.8 litres of water to 2kg of compound.
Packing mix: 1.35 litres of water to 2kg of compound.
