Usage

Sikacrete®-114 AE is used for the structural repair of deteriorated concrete.
It is ideal for casting sections or members where the volumes required are too large for conventional grouts, and too small and inaccessible for normal concreting applications.
A typical application is the re-profiling of damaged concrete members, using formwork.
Also suitable for base plate grouting where thickness exceeds 75 millimetre.

Application steps

MIXING

Always empty the full contents of the bag into a suitable mixer.
Mix dry for 3 minutes before adding the water.
Add 3.5 to 3.75 litre of water per 40 kilogram bag.
Mixing can only be achieved using either a slow speed drill (400 to 600 rpm) fitted with clean, rust free, mixing paddle, or a forced action mixer.
Do not mix by hand or mix part bags!
For best results, first add 3.0 to 3.3 litre of water and mix for at least 3 minutes or until the larger aggregate has thoroughly dispersed and a uniform, free flowing consistency is obtained.
Then add remaining water and mix for additional 2 minutes.

APPLICATION

Dampen all concrete surfaces thoroughly with clean water prior to application.
Before pouring, however, let the mixed grout stand for 2 to 3 minutes after mixing with the mixing water to allow entrapped air to escape.
Maintain sufficient hydrostatic head to keep the product flowing.
Provide channels for the air to escape during grouting.
Protect from rain until initial set has been achieved.

CURING TREATMENT

Treat exposed surfaces with Antisol-E Curing Compound or use other approved curing methods such as polyethylene sheeting or wet hessian.
Do not commence fogging until final set has been reached.

CLEANING OF EQUIPMENT

Clean equipment and mixer after application with water.
Hardened material can only be removed mechanically.
