Injection Mortar
Description
A specially formulated dry mix of cement,
quartz and reactive chemicals which when
mixed with water, and inserted as described
will create a chemical damp-proof course.
The product is particularly useful
in random stone wall constructions.
The chemicals released react and form a
crystalline growth which penetrates and
blocks the capillaries, pores and fine cracks
in mortar joints.

Lectros Waterproofer
First Coat
|
1
|
Mix 3 parts sand to 1 part cement.
|
|
2
|
Mix gauging water with Lectro Proof
at 30-1 ratio as specified.
|
|
3
|
Add minimum amount of gauging water
to dry mix to ensure a dense coat.
An approximation of not more than
8 litres per 50 kilos of dry mix should
be used, as a guide.
|
|
4
|
Render the surface to give an overall
thickness of between 10-15mm ensuring
that the mix is compacted into the
joints. Scratch to form a key when
the cement obtains its first set.
Do not overtrowel.
|
|
|
 |
|
|
Second Coat
This mix is as for the first coat applied to give
an overall thickness for two coats of about 25mm.
Apply this coat before the first coat has finally
set in order to obtain satisfactory adhesion between
the rendering coats. Scratch the surface to form
a key. Do not overtrowel.
Finish Coat
This should be a porous mix of multi finish or
similar board finish.
