Usage

Sikacrete®-214 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 procedures. A typical application is the re-profiling of damaged concrete members, such as the underside of bridge beams, using formwork. Sikacrete®-214 provides a compatible surface for the application of Sika coatings and finishes.

Application steps

MIXING

Mixing can only be achieved using either a slow speed drill (set at 400 - 600 rpm) fitted with a clean, rust free, mixing paddle, or standard mortar mixing equipment. DO NOT ATTEMPT TO MIX BY HAND.
Add 3,0 -3,12 litres of water to a suitable mixing vessel and then add Sikacrete®-214 powder slowly whilst mixing. Mix for at least 3 minutes until you have a homogenous mix, then add the 5kg bag of aggregate to the grout and mix until aggregate has thoroughly dispersed and a uniform, free-flowing consistency is obtained. Full mixing time should be 5 minutes.

APPLICATION

Dampen the surface thoroughly with clean water prior to the application of Sikacrete®-214.
Place the mixed Sikacrete®-214 directly after mixing ensuring that any displaced air is allowed to escape. Maintain sufficient hydrostatic head to keep the product flowing.
Protect from rain until initial set has been achieved.

CURING TREATMENT

Where ambient conditions may lead to rapid surface drying, the use of light water fogging for 48 hours or suitable water based curing compound is recommended. (Do not commence fogging until initial set has been reached; typically 1 - 2 hours depending upon ambient conditions).

CLEANING OF TOOLS

Clean all tools and application equipment with water immeadiately after use. Hardened material can only be mechanically removed.
