Roof Waterproofing System:

-20 °C to +80 °C max

Sikalastic®-611 R AP resists contact with weak acids and alkalis regulated by JIS A 6021.

+5 °C min / +40 °C max

+5 °C min / +40 °C max

5% min / 80% max Relative Humidity

Beware of condensation. The substrate and uncured applied membrane must be at least +3 °C above dew point to reduce the risk of condensation or blooming on the membrane finish.

+5 °C min / +40 °C max

Refer to Product Data Sheet of the appropriate primer

Product will cure rapidly in high temperatures combined with high air humidity. Skin formation starts after ~2 hour (+20 °C / 50 % r.h.).

Be aware that impact of heavy or rain showers can physically damage the still liquid membrane.

Note: Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity

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

*Ferrous, stainless steel, aluminium, lead, zinc; Factory coated metal sheeting must be tested for adhesion before proceeding

NOTE: 

For thecomsumption rates and waiting time / overcoating please refer to the PDS of the appropriate cleaner and primer. Other substrates most be testedfor their compatibility. If in doubt, applly a test area first.

IMPORTANT

Avoid over-mixing to minimise air entrainment.

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

Equipment: 

• Fleece roller
• Brush

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

Reinforced waterproof membrane

Equipment: 

• Fleece roller
• Brush
• Float trowels

1st 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
 

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.

2nd 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.
 

Top coat
 

1. Install the detailing first (such as corners, upstands, joints) before installation of the main horizontal surfaces.
2. Mix 2-part top coat according to Product Data Sheet.
3. Pour the mixed Product onto the substrate. The consumption is specified in the individual primer Product Data Sheet Application Information.
4. Apply the Product with 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.

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