Storage conditions
The product must be stored properly in original, unopened and undamaged sealed packaging in dry conditions at temperatures between +5 °C
and +30 °C.
Density
| ~1.37 kg/L (+30 °C) | (EN ISO 2811-1) |
Solid content by mass
~60 %
System structure
| Layer | Product |
| Primer | Sikalastic®-10 Primer W |
| Base coat | Sikalastic®-510 CoolCoat IN |
| Top coat | Sikalastic®-510 CoolCoat IN |
| (Optional) Clear coat | Sikalastic®-10 Primer W |
Important: Do not overcoat Sikalastic®-510 CoolCoat IN with tile, concrete or others. Sikalastic®-510 CoolCoat IN is an exposed system.
Important: For larger application areas and high demanding applications, use a glass fabric reinforcement Sika® Fabric-50 between the coats. For normal exposures, usage of Sika® Fabric-50 is optional. Reinforcement (partial or total) must be used over dynamic cracks and joints.
Important: For enhanced dirt pick up resistance and easy cleanability, above build up must be further coated with a thin layer of Sikalastic®-10 Primer W.

Application
Ambient air temperature
+5 °C min. / +40 °C max.
Relative air humidity
80 % max.
Dew point
Beware of condensation. The substrate and uncured applied roof material must be at least +3 °C above dew point to reduce the risk of condensation on the surface finish.
Substrate temperature
+5 °C min. / +40 °C max.
Substrate moisture content
≤ 6 % 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 (Polyethylene-sheet).
Waiting time to overcoating
| Base layer | Overcoating layer | Waiting time |
| Sikalastic-10 Primer W | Sikalastic®-510 CoolCoat IN | ~30 min |
| Sikalastic®-510 CoolCoat IN | Sikalastic®-510 CoolCoat IN | ~6 h |
Note: Above values are at +30 °C and 50 % relative humidity. Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity.
Applied product ready for use
| Light traffic | ~24 h |
IMPORTANT
Applied Sikalastic®-510 CoolCoat IN must not be subjected to ponding before 7 days. Contact Sika Technical Services and refer to ASTM D5957 for more information.
Consumption
~1.2–1.5 kg/m2 in 2 coats
Note: The consumption will vary depending on application area, substrate type, substrate roughness, surface profile, absorption of the surface and thickness required.
EQUIPMENT
Substrate Preparation Equipment
- Abrasive blast cleaning / planing / scarifying or grinding equipment
- Manual or mechanical wire brushes
- High pressure power washer
Mixing Equipment
-
Electric single paddle mixer (300–400 rpm)
Application Equipment
- Brush: Soft bristle
- Roller: Solvent resistant, “non-fuzzy”
MIXING
Important: Avoid over-mixing to minimise air entrainment.
Note: Use an electric single or double paddle mixer (300–400 rpm) with spiral paddle for mixing.
- Product is supplied ready for use.
- Before application, mix for at least 1 minute or until the liquid and all the coloured pigment has achieved a uniform colour.
APPLICATION
Important: Protect the coating from damp, condensation and direct water contact for at least 24 hours.
Important: If applied on porous substrates during rising temperatures pin holes may occur from rising air. Apply during falling temperatures.
Important: Do not apply on roofs with improper slopes leading to long ponding.
Important: Do not allow temporary ponding to remain between coats on any horizontal surfaces or until the final coating has totally cured. Brush or mop surface water away during this time.
PRIMER
- Pour the mixed primer onto the prepared substrate.
- Apply the product evenly over the surface with a brush or fleece roller. Ensure a continuous pore free coat covers the substrate.
- Back roll the surface in two directions at right angles with a fleece roller.
ROOF WATERPROOFING
Important: Apply 2 coats at the same consumption.
- Pour the mixed product onto the prepared substrate (for brush or roller application).
- Apply the product evenly over the surface with a short pile roller, a brush or airless spray. Note: The consumption is specified in Application Information.
- (Optional) Wherever coating is to be reinforced with glass fabric, lay Sika® Fabric-50 into the freshly applied base coat and embed firmly into the wet coat with brush. Reinforcement overlaps must be a minimum of 50 mm.
- After the inter-coat waiting time apply a second coat over the surface with a short pile roller, a brush or airless spray.
- (Optional) Apply one thin coat of Sikalastic®-10 Primer W for enhanced dirt resistance and cleanability.
CLEANING OF EQUIPMENT
Clean all tools and application equipment with suitable solvent like NC thinner,etc immediately after use. Hardened material can only be removed mechanically.
