SikaShield® P35 MG IN 4 mm
4 mm polyester-reinforced APP bituminous membrane, flexible to -5 C
Product Overview
SikaShield® P35 MG IN 4 mm is a heavy-duty APP (atactic polypropylene) modified bituminous waterproofing membrane reinforced with a non-woven polyester carrier and finished with decorative mineral granules, engineered to remain flexible down to -5 C. The thicker 4 mm sheet combines the high-performance P35 formulation with extra mechanical robustness for the most demanding waterproofing. Torch-applied, it bonds fully to a primed substrate once the burn-off underside film is melted, creating a seamless layer with high tensile, tear and joint-shear strength and watertightness to at least 60 kPa. It is specified on roofs up to 15% gradient, terraces, decks, podiums and bridge decks under asphalt, as a single layer or robust cap sheet. Space Arc Engineering, an authorized Sika distributor in India, supplies this membrane nationwide.
Features & Benefits
- Thick 4 mm high-performance body for maximum durability and puncture resistance
- Flexible to -5 C for cold climates and structures subject to movement
- Watertight to at least 60 kPa for the most demanding waterproofing duties
- High joint-shear resistance for secure, long-lasting laps
- Withstands impact (>=1000 mm) and static load (>=10 kg)
- Mineral-granule, UV-resistant top that can be tiled or painted over
Technical Highlights
| Coverage | Rolls of 1.0 m x 10.0 m; include 80-100 mm side and 150 mm end overlaps in quantity estimates. |
| Strength | Tensile 600 +/-120 N/50mm (MD) and 450 +/-90 N/50mm (CMD); joint shear 600 +/-120 N/50mm (MD); elongation 45 +/-15%. |

Frequently Asked Questions
What is SikaShield P35 MG IN 4 mm?
It is a heavy-duty 4 mm APP-modified bituminous waterproofing membrane with non-woven polyester reinforcement and a mineral-granule top, flexible to -5 C and watertight to at least 60 kPa, torch-applied to roofs and decks.
When should I choose P35 4 mm over the other SikaShield grades?
Choose it when you need both the higher-performance P35 properties (flexibility to -5 C, >=60 kPa watertightness) and the extra thickness of a 4 mm sheet for maximum durability on heavily loaded or critical waterproofing.
What substrates is it suitable for?
It torch-bonds to primed concrete, cementitious screeds, plastered masonry, compatible coatings and smooth bituminous membranes. Keep substrate moisture below 6% and use a SikaShield primer.
What are the installation conditions?
Torch-apply at ambient and substrate temperatures of +5 C to +40 C, lapping 80-100 mm at sides and 150 mm at ends. Refer to the TDS for full application detailing.
