Product Description
(Formerly Sika WP Shield Primer)
DESCRIPTION
SikaShield Primer W-30 IN is single component, quick
drying, water based modified bituminous primer
which penetrates and activates the substrates. It improves
adhesion between the substrate and preformed
bituminous sheet membranes in SikaShield
range.
USES
Used as a primer for better adhesion of the torch-on
and stick-on Atactic Poly Propylene (APP) and Styrene
Butadiene Styrene (SBS) modified bituminous waterproofing
membranes.
CHARACTERISTICS / ADVANTAGES
Excellent bond with concrete, screed mor tar, porous
stones and lime-concrete substrates
Bonds well with old bituminous substrates
Easy application by brush, spray or roller
Good penetration in cementitious substrates
Effective activation of the surface to receive the waterproofing
sheet membrane
Specially designed for tropical conditions

BASIS OF PRODUCT DATA
All technical data stated in this Product Data Sheet are
based on laboratory tests. Actual measured data may
vary due to circumstances beyond our control.
ECOLOGY, HEALTH AND SAFETY
User must read the most recent corresponding Safety
Data Sheets (SDS) before using any products. The SDS
provides information and advice on the safe handling,
storage and disposal of chemical products and contains
physical, ecological, toxicological and other
safety-related data.
APPLICATION INSTRUCTIONS
Strictly follow installation procedures as defined in
method statements, application manuals and working
instructions which must always be adjusted to the actual
site conditions.
SUBSTRATE QUALITY
Concrete, lime-concrete and mor tar 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.
SUBSTRATE PREPARATION
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.
MIXING
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.
APPLICATION
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.
