The product must be stored properly in original, unopened and undamaged sealed packaging in dry conditions at temperatures between +5 °C and +30 °C. Protect from moisture and direct sunlight.
Higher storage temperatures may reduce shelf life of product.

Waterproofing without reinforcement

• For detailed system build up, please refer to table below

Waterproofing with reinforcement (Sika® Fabric-50 or Sika® Reemat Premium-225)

• Sika® Fabric-50 or Sika® Reemat Premium-225 is applied at areas with movements, irregular substrate or to bridge cracks, joints and seams on the substrate as well as for details.
• For detailed system build up, please refer to table below

Protection layer

• Apply one or two layers of aliphatic overcoat from the Sikalastic® range over the Sikalastic®-610 R IN membrane.
• Alternatively, protect with a protection screed after applying a suitable separation layer.

Note: These figures are theoretical and do not include for any additional material required due to surface porosity, surface profile, variations in level and wastage

~0.2 %

Good resistance to acidic and alkali solutions (5 %), detergents, seawater, and oils.

+10 °C min. / +40 °C max.

20 % min. / 85 % max.

Beware of condensation. Substrate temperature and uncured material during application must be at least +3 °C above dew point.

+10 °C min. / +40 °C max.

< 4 % parts by weight
The following test methods can be used: Sika®-Tramex meter, CM-measurement or Oven-dry-method. No rising moisture according to ASTM D4263 (Polyethylene-sheet).

No water / moisture / condensation on the substrate.

Note: Above values are at +30 °C and 50 % relative humidity. The drying time of the coating will be affected by changing ambient conditions particularly temperature and relative humidity. Low temperature and high relative humidity retard curing, while high temperature and low relative air humidity accelerate curing progression.

Note: Above values are at +23 °C and 50 % relative humidity. Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity.

1.2–1.8 kg/m² applied in two or three layers.

Note: The consumption will vary depending on application area, substrate type, substrate roughness, surface profile, absorption of the surface and thickness required.

Select the most appropriate equipment required for the project:

Substrate preparation equipment

• Abrasive blast cleaning / planing / scarifying or grinding equipment
• Manual or mechanical wire brushes
• High pressure power washer

For other types of preparation equipment, contact Sika Technical Services.

Mixing equipment

• Electric single or double paddle mixer (300–400 rpm) with spiral paddle

Application equipment

• Brush: Soft bristle
• Roller: Solvent resistant fleece
• Float trowels
• Airless spray

The supporting structure must be of sufficient structural strength to apply all new and existing layers of the roof build-up. Complete roof system must be designed and secured against wind uplift loadings. Refer to the Sika Method Statement: Sikalastic®-610 R IN

Suitable substrates:

• Concrete and cementitious substrates 
• Metal
• Bituminous sheet membranes
• Bituminous coatings
• Brick
• Unglazed ceramic tiles

Cementitious substrate:

• New concrete should be cured for at least 28 days and should have a pull off strength ≥ 1.5 N/mm².
• Cementitious or mineral based substrates must be prepared mechanically using abrasive blast cleaning or scarifying equipment to remove cement laitance and to achieve an open textured surface.
• Loose friable material and weak concrete must be completely removed and surface defects such as blowholes and voids must be fully exposed.
• Repairs to the substrate, filling of joints, blowholes/voids and surface levelling must be carried out using appropriate products from the Sikafloor®, Sikadur® and Sikagard® range of materials.
• High spots must be removed by grinding.

All other substrates:

• All contamination such as dust, loose and friable material that could affect final finish or reduce adhesion, must be completely removed from all surfaces before application of the product or subsequent products, preferably by industrial vacuuming equipment.

IMPORTANT

Avoid over-mixing to minimise air entrainment.

1. Product is supplied ready to use. Before application, mix for at least 1 minute or until the liquid is uniform.

IMPORTANT

Protect from rain

After application, the product must be protected from heavy rain or rain showers until dry to prevent surface damage.

IMPORTANT

Application of successive coats

To prevent a reduction in product performance the following actions are necessary when applying successive coats.

1. Ensure product is totally dry and the surface is without pinholes before applying successive coats.
2. Remove surface water between coating applications.
3. Confirm overcoating times have been achieved between coating applications.

IMPORTANT

No application on rising moisture

Do not apply on substrates with rising moisture.

INSTALLATION PROCEDURE

Reference must be made to further documentation where applicable, such as a relevant method statement, application manual and installation or working instructions.

PRIMER

1. Pour the mixed Product onto the surface. The consumption is specified in the individual primer Product Data Sheet Application Information.
2. Apply the Product evenly over the surface with a brush or fleece roller.
3. Back roll the surface in two directions at right angles with a fleece roller. 

The coating is continuous and pore free.

ROOF WATERPROOFING
Base coat
 

1. Install the detailing first (such as corners, upstands, joints) before installation of the main horizontal surfaces.
2. Pour the mixed Product onto the substrate. The consumption is specified in Application Information.
3. Apply the Product with either a trowel, brush or a fleece roller.
4. IMPORTANT Avoid going back to re-work areas that are partially dried as this may damage the surface finish. Back roll the surface in two directions at right angles with a fleece roller.

The coating is continuous and pore free.

Reinforcement application (Optional)
 

1. For the best results work 1.0 m at a time lengthways applying the 1st coat and embedding the reinforcement.
2. Make sure reinforcement overlaps are greater than 50 mm.
3. Lay the reinforcement onto the wet 1st coat.
4. Use a short pile roller to roll over the reinforcement and resin.

The coating is continuous and pore free.

  
Top coat
 

1. Check if the reinforcement is embeded properly, if necessary use sand paper to unsure that the surface is even. If the surface was contaminated with dust or dirt clean the surface with water and light detergent, wait until the surface is dry before applying 2nd coat. Remove any standing water before application. 
2. Install the detailing first (such as corners, upstands, joints) before installation of the main horizontal surfaces.
3. Pour the mixed Product onto the substrate. The consumption is specified in Application Information.
4. Apply the Product with one either a brush or a fleece roller.
5. IMPORTANT Avoid going back to re-work areas that are partially dried as this may damage the surface finish. Back roll the surface in two directions at right angles with a fleece roller.

The coating is continuous and pore free.

Extra coat (optional for high build applications)

1. Install the detailing first (such as corners, upstands, joints) before installation of the main horizontal surfaces.
2. Pour the mixed Product onto the substrate. The consumption is specified in Application Information.
3. Apply the Product with one either a brush or a fleece roller.
4. IMPORTANT Avoid going back to re-work areas that are partially dried as this may damage the surface finish. Back roll the surface in two directions at right angles with a fleece roller.

The coating is continuous and pore free.

Protective coat

1. Protect the final coat with a UV protection coat or protective screed after applying a separation layer.

Clean all tools and application equipment with Sika® Thinner C immediately after use. Hardened material can only be removed mechanically.
