ECOLOGY, HEALTH AND SAFETY

User must read the most recent corresponding Safety

Data Sheets (SDS) before using any products. The SDS

provides information and advice on the safe handling,

storage and disposal of chemical products and contains

physical, ecological, toxicological and other

safety-related data.

APPLICATION INSTRUCTIONS

EQUIPMENT

SikaRep Microcrete-4 can be mixed both in paddle

type and slow speed (max. 500 rpm) grouting mixer or

drum type concrete mixer.

SUBSTRATE QUALITY / PRE-TREATMENT

The substrate should be prepared by suitable mechanical

preparation techniques such as high pressure

water, breakers, grit blasting, scabblers, etc.

Concrete surfaces must be sound, clean, free from

frost, oils, grease, all loosely adhering particles and

other surface contaminants. All absorbent surfaces

must be well saturated with clean water, but be free

of any surface water or puddles immediately prior to

the application of produced micro-concrete.

Metal surfaces (iron and steel) should be clean, free

from scale, rust, oil and grease.

Bonding agent and steel protection

Embedded steel reinforcing should be free from scale,

rust, oil and grease, and treated with a suitable anticorrosion

coating such as Friazinc R, SikaTop

Armatec-108 Plus or SikaTop Armatec-110 Epo-

Cem. The application of a suitable bonding agent,

such as Sikadur-32 LP IN or SikaTop Armatec-110

EpoCem, will improve adhesion on large areas or

where particularly dense concrete substrates are involved.

MIXING

Place about 8090 % of the premeasured clean water

into a clean mixer and gradually add the whole

bag of SikaRep Microcrete-4 into it while continuously

mixing.

Add the remaining water and additional clean 510

mm aggregates (if needed as per design) until the

desired consistency is obtained.

3. Mixing time should be minimum 3 minutes.

IMPORTANT

Concrete can also be produced with addition of 10

mm down properly graded silt-free aggregate in proportion

of 2 : 1 (SikaRep Microcrete-4 : coarse aggregate)

by weight.

IMPORTANT

Do not mix more material, which cannot be used within

pot life.

IMPORTANT

Do not add extra water.

IMPORTANT

Mix only full bags for best results.

APPLICATION

Strictly follow installation procedures as defined in

method statements, application manuals and working

instructions which must always be adjusted to the actual

site conditions.

IMPORTANT

Formwork

Ensure formwork is secure and watertight to prevent

movement and leaking during placing and curing.

IMPORTANT

Working in thick sections

Do not pour more than 100 mm of layer thickness

without addition of aggregates.

Small localised repairs

Small volume mixing may carried out with a suitable

low-speed (500 rpm) drill and mixing paddle. After

mixing, stir lightly with a spatula for a few seconds to

release any entrapped air. The microconcrete is then

poured immediately into the prepared formwork.

Large repairs

When carrying out large scale repairs or column /

beam jacketing, ensure sufficient pressure head is

maintained for uninterrupted concrete flow. Formwork

must be firmly placed and kept watertight. When

placing microconcrete over large area, it is important

to maintain a continuous flow throughout the process.

Work sequence and equipment must be properly organised

to ensure an uninterrupted flow of microconcrete.

Ensure proper air displacement when pouring.

In large areas, microconcrete may be mixed and

pumped using heavy duty screw feed and piston

pumps. Equipment suitability should be tested and

checked prior to actual grouting works.

Cold weather working

Consider storing bags in a warm environment and using

warm water to assist with achieving strength gain

and maintaining physical properties.

Hot weather working

Consider storing bags in a cool environment and using

cold water to assist with controlling the exothermic reaction

to reduce cracking and maintaining physical

properties.

CURING TREATMENT

Formwork must remain in place for at least 3 days.

Upon removal of the formwork, cure the exposed surfaces

immediately with Sika Antisol curing compound

or use other approved curing methods.

CLEANING OF TOOLS

Clean all tools and application equipment with water

immediately after use. Hardened or cured material

can only be removed mechanically.

LOCAL RESTRICTIONS

Note that as a result of specific local regulations the

declared data and recommended uses for this product

may vary from country to country. Consult the local

Product Data Sheet for exact product data and uses.
