Bitumen, water and additives

12 months from date of production

Store properly in original unopened, sealed and undamaged packaging, in covered area at temperatures between +20 °C and +35 °C. Store vertically with top side up. Protect from direct sunshine, rain, snow, ice, etc.

SikaShield® Primer W-30 IN must be diluted with 20 % to 50 % clean water to achieve the desired consistency.

NOTE

In case of exceptional site conditions, higher dilution can be done based on site trials and advise of Sika Technical Service.

+10 °C min. / +40 °C max.

+10 °C min. / +40 °C max.

Test method: Sika®-Tramex meter

The above values are at 23 ± 2 °C and 50 ± 5 % relative humidity and may vary according to the change in temperature, humidity, ventilation, wind, substrate quality, etc.

0.200–0.400 kg/m² per coat (diluted)

NOTE

These figures are theoretical and does not consider any additional material required due to surface porosity, surface profile, variations in level or wastage etc.

Strictly follow installation procedures as defined in method statements, application manuals and working instructions which must always be adjusted to the actual site conditions.

• Concrete, lime-concrete and mortar screed surfaces must be clean, free from grease, oil & loosely adhering particles.
• 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 to be prepared mechanically using wire brush, grinder, abrasive blast cleaning or scarifying equipment to remove cement laitance and to achieve an open textured surface.
• Loose friable material and weak concrete to be completely removed and surface defects such as blowholes and voids must be fully exposed.
• Use Sikadur® or SikaLatex® or Sika MonoTop® range of repair materials for filling in potholes, voids or cracks on the substrates. 
• The cementitious substrates to be carefully assessed for moisture content, air entrapment, and surface finish prior to any primer application.

SikaShield® Primer W-30 IN is mixed with clean water up to maximum 50 % to achieve desired consistency. Stir the contents well before application.

IMPORTANT

The primer may become high viscous due to change in ambient conditions like temperature and humidity that might affect the consistency and increase consumption of the primer. Under such situation, a site modification by further diluting the primer as per the advice of the Sika Technical Service may be necessary to achieve the desired application consistency. The dilution is to be fixed on the basis of site trials but not to exceed 50 % by weight of the primer.

IMPORTANT

Do not apply SikaShield® Primer W-30 IN when it is raining or when rain is imminent.

IMPORTANT

Do not apply SikaShield® Primer W-30 IN on substrates with oil or grease contamination.

IMPORTANT

Do not apply SikaShield® Primer W-30 IN on dry surface in extreme hot weather. Surface must be cooled by spray or mist of water before application.

IMPORTANT

Apply the membrane within 24 hours of primer application.

1. Apply bituminous primer to a clean, smooth and dry surface by brush, roller or spray in single coat as per consumption given. Ensure full wetting and coverage of the surface.
2. In some cases, a second coat of primer may be necessary, allow 24 hours between successive coats.
3. Application of bituminous membranes must be done soon after the primer is hard dry.

Clean all tools and application equipment with water immediately after use. Hardened and/or cured material can be removed mechanically or using thinner.
