The Product must be stored in original, unopened and undamaged sealed packaging in dry conditions at temperatures between +5 °C and +40 °C. Protect from frost and humidity.

NOTE: Crystalline compounds in Sika®-101h penetrates into the concrete up to complete capillary depth available, in the process forming crystals and multiplying to keep sealing the capillaries bottom upwards constantly reducing the ingress of water. This takes some time to happen as the process of migration of the crystal forming compounds depend on various other factors like, quality and grade of concrete, cover of concrete, porosity of concrete, presence of free lime, etc. Hence minimum of 28 days of exposure of the coating under normal site conditions after application is recommended.

This figure is theoretical and does not allow for any additional material due to surface porosity, surface profile, variations in level or wastage etc.

Substrate preparation

• Mechanical or very high pressure water blasting

Mixing

• Low speed (< 500 rpm) hand drill mixer
• Mixing container

Application

• Slurry brush
• Dry shake spreader / sieve

Curing

• Water spray equipment, moist geotextile membrane, polyethylene sheet

As a Crystalline Coating

Add Sika®-101h to the requisite amount of water and stir with low speed single or double spindle mortar mixer at low speed (300-500 rpm) for 3-5 minutes until a lump free smooth brushable consistency is achieved.

As an Integral Waterproofing Admixture 

Sika®-101h must be added to the concrete at the time of batching. The sequence of procedures for addition will vary according to the type of batch plant operation and equipment (for e.g. RMC dry batch operation, RMC central mix operation, site batching in 50 kg mixer, etc.). In all cases the objective should be to ensure complete dispersion of the powder in the mix.

IMPORTANT

Do not apply on old rendered substrates.

IMPORTANT

Protect the fresh mortar from rain, strong winds and direct sunshine at least 24 hours.

IMPORTANT

When protecting with a plaster, clean surface using high speed water jet after approx. 28 days of application of final coating, followed by application of acrylic bonding agent, scratch coat of plaster and final protection plaster. Please contact Sika Technical Services team for further guidance.

IMPORTANT

When used as an admixture, in some cases little retardation is possible depending on the concrete mix design and the dosage rate of Sika®-101h. Please consultant Sika Technical Services Team for advice.

​​​​​​As Crystalline slurry coating:

1. Thoroughly saturate the prepared substrate before application with clean water to achieve a saturated surface dry (SSD) surface. Before application remove excess water, e.g. with a clean sponge.
2. Apply mixed material onto the prepared pre-wet substrate by suitable slurry brush by working the slurry well into the substrate and without the formation of voids.
3. A 2^nd layer should be applied ‘wet on wet’ after allowing 1^st layer to slightly stiffen to ensure full coverage of the surface and avoid ‘pin-holes’.

​​​​​​As Crystalline dry shake:

1. Spread uniformly the powder on saturated or green substrate according to consumption.​​​​

As Integral waterproofing admixture:

1. Add the powder at time of batching according to consumption.

Protect fresh mortar immediately from premature drying using an appropriate curing method, e.g. water spray, moist geotextile membrane, moist hessian cloth, moist gunny bags, polyethylene sheet, etc. Cure at least for 5 days after application. For full cure approx. 28 days is recommended.

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