GRACE POLYGUARD PU COATING
Single component, Elastomeric, Crack bridging, waterproofing base coat
Product Description:
GRACE POLYGAURD Waterproofing PU Coating is a high-performance polyurethane-based waterproofing solution designed to provide superior protection against water infiltration and weathering. Formulated with advanced polymer technology, this coating forms a seamless, flexible membrane over various substrates, offering long-lasting waterproofing and durability in demanding environments
Key Features and Benefits:
Exceptional Waterproofing: Forms a seamless barrier to prevent water penetration. High Flexibility: Maintains elasticity to accommodate substrate movement without cracking. UV Resistance: Provides excellent resistance to UV degradation, ensuring long-term performance. Chemical Resistance: Resists damage from common chemicals and pollutants. Easy Application: Can be applied by spray, brush, or roller for versatile installation. Quick Cure Time: Rapid curing allows for faster project completion. Environmentally Friendly: Low VOC formulation for reduced environmental impact.
Typical Applications:
Roof Waterproofing
Basement Waterproofing
Flooring Protection
Foundation Waterproofing
Bridge Deck Waterproofing
Tank and Vessel Coatings
Sports flooring
Metal:
Should be thoroughly cleaned by grinding or blast cleaning to near white metal (SSPCSPS-10).
Coverage:
First coat: 0.6 – 0.8 kg/m²
Second coat: 0.6 – 0.8 kg/m²
Total consumption: 1.2 – 1.6 kg/m² to give
1mm dry film thickness.
STORAGE & SHELF LIFE:
Shelf life is 1 year when stored under cover, out of direct sunlight and protected from extremes of temperature. Failure to comply with the recommended storage conditions may result in premature deterioration of the product or packaging. For specific storage advice consult Grace Chemical Technical Services Department.
HEALTH & SAFETY:
As with all chemical products, care should be taken during use and storage to avoid contact with eyes mouth, skin and foodstuffs. Treat splashes to eyes and skin immediately. If accidentally ingested, seek medical Attention. Reseal containers after use. Use in well ventilated areas and avoid inhalation
IMPORTANT NOTE:
Field service, where provided, does not constitute supervisory responsibility. For additional information contact your local Grace Representative. Grace Chemicals reserves the right to have the true cause of any difficulty determined by accepted test methods.

APPLICATION INSTRUCTION:
The application temperature should be between 5°C to
55°C. Application procedures may vary slightly
depending upon site conditions.
surface preparation:
Surface must be clean, dry and sound with an open texture. Remove dust, laitance, grease, curing compounds, bond inhibiting impregnations, waxes, and any other contaminants. All projections, rough spots, etc. should be dressed off to achieve a level surface prior to application
concrete:
Should be cleaned and prepared to achieve a laitance and contaminant free, open textured surface by blast cleaning or equivalent mechanical means (CSP 3-4 per ICRI guidelines).
PLYWOOD:
Should be clean and smooth, APA and exterior grade,
not less than 1/2” thick, and spaced and supported
according to APA guidelines. Seams should be sealed
with 2c or 1a and detailed and may need embedded
fabric reinforcement
LIMITATIONS:
To avoid dew point conditions during application
relative humidity must be no more than 95 % and
substrate temperature must be at least 5 °F (3 °C)
above measured dew point temperature.
Minimum ambient and substrate temperature during
application and curing of material is 40 °F (4 °C);
maximum is 95 °F (35 °C).
Do not store materials outdoors directly exposed to
sunlight and moisture. Cover and protect materials
with breathable type covers such as canvas tarpaulins
to allow venting and protection from weather and
moisture. Observe temperature storage and
conditioning requirements.
Do not thin with solvents. Minimum age of concrete
must be 21–28 days, depending on curing and drying
conditions.
Any repairs required to achieve a level surface must be
performed prior to application (consult a GRACE
Representative for guidance on various product
solutions). Surface irregularities may reflect through ▪
the cured system. Do not apply to a porous or damp
surface where moisture vapor transmission will occur
during application and cure.
• Substrate must be dry prior to application. Do not apply
to a frosted, wet or damp surface. Do not proceed if rain
is imminent within 8–12 hours of application. Allow
sufficient time for the substrate to dry after rain or
inclement weather as there is the potential for bonding
problems.
