BASIS OF PRODUCT DATA

All technical data stated in this Product Data Sheet are

based on laboratory tests. Actual measured data may

vary due to circumstances beyond our control.

IMPORTANT CONSIDERATIONS

Do not exceed water addition.

▪

Not to be used for concrete repair works.

▪

Do not use vibrating pokers.

▪

Use only on clean, sound substrate.

▪

Avoid application in direct sun and / or strong wind.

▪

Pour or pump from one side only.

▪

Keep exposed surfaces to a minimum.

▪

Do not add additional water during the surface fin-

ishing, as this will cause discoloration and / or crack-

ing.

▪

Protect freshly applied material from freeze-thaw ac-

tion.

▪

To avoid cracking in warm temperatures, keep bags

cool and use cold water.

ECOLOGY, HEALTH AND SAFETY

For information and advice on the safe handling, stor-

age and disposal of chemical products, users shall

refer to the most recent Safety Data Sheet (SDS) con-

taining physical, ecological, toxicological and other

safety-related data.

APPLICATION INSTRUCTIONS

SUBSTRATE QUALITY / PRE-TREATMENT

Concrete, mortar, stone:

Surfaces must be sound, thoroughly clean, free from

ice, oils, grease, standing water and any loose or fri-

able particles, and any other surface contaminants.

Steel, iron:

Clean, free from oil or grease, rust and scale, etc.

Shutter / Formwork:

Where formwork is to be used, all formwork should be

of adequate strength, treated with release agent and

sealed to prevent leakage. Sealing can be achieved by

using Sikaflex®-11FC+ sealant beneath or around form-

work, and between joints. Ensure formwork includes

outlets for extraction of the pre-soaking water.

A header box / hopper should be constructed on one

side of the formwork so that a grout head of 150 to

200 mm can be maintained during the grouting opera-

tion.

MIXING

Pour the required quantity of clean water (4.5 litres

per 25 kg bag, or 180 litres per one tonne) into the

mixing vessel for each complete unit of Parex 100

Newton Grout to be used. Slowly add the powder to

the water whilst continually mixing. Mechanical mixing

should be carried out using either a high torque slow

speed drill with a grout stirrer, or a grout mixer set on

slow speed for small mixes. For larger mixes, use

forced action type mixers (high speed or colloidal mix-

ing may cause thixotropy leading to loss of flow). This

material is not suitable for mixing by hand. It is of up-

most importance that the product is mixed thoroughly

enough that a grout consistency is obtained without

the addition of further water (at least 3 minutes).

Fresh grout should be allowed to stand until the air

entrapped by mixing has been released.

APPLICATION

Grout should be placed within 10 minutes of mixing,

or 60 minutes if kept mobile prior to placing. Continu-

ous placing is important, pouring or pumping from one

side of the form until the grout appears at the oppos-

ite side of the grouting area. Do not disturb once

grouting has been completed. Parex 100 Newton

Grout may be placed at temperatures between 5°C

and 35°C.

For placing at temperatures outside this range, con-

tact Sika® Technical Services Department for advice.

CURING TREATMENT

After the grout has initially hardened, remove form-

work and trim edges while concrete is ‘green’.

Protect the fresh material from premature drying us-

ing an approved curing method (e.g. curing compound

such as Sikafloor® ProSeal, moist geo-textile mem-

brane, hessian, polythene sheet, etc.). In cold weath-

er, apply heat blankets to maintain a constant temper-

ature.

Placed grout, which is exposed, should be cured in ac-

cordance with good concrete practice.
