51.78 gal - 4
Material Use:
ALSAN CIVIL P70 is a clear, two-component, fast-curing polymethyl methacrylate (PMMA) primer designed to enhance adhesion in waterproofing systems. It is primarily used as a primer within the ALSAN CIVIL, ANTIROCK, and TRAFIKROCK systems for civil engineering applications such as bridges, parking decks, and other concrete or steel structures. Additionally, when mixed with silica sand, it can be used for small to medium-sized concrete surface repairs.
System Components:
ALSAN CIVIL P70 is used in conjunction with ALSAN RS CATALYST POWDER, which initiates the curing process. It serves as the primer layer in the ALSAN CIVIL, ANTIROCK, and TRAFIKROCK waterproofing systems. When used for repairs, it is combined with silica sand in a typical ratio of 1 part resin to 2 parts sand by volume. The primer is compatible with subsequent PMMA-based base coats and topcoats used in these systems.
Applications:
This product is suitable for use on both concrete and steel substrates. It is applied as a primer to improve adhesion of waterproofing membranes and coatings in high-performance civil engineering applications. It can also be used to perform concrete patching and leveling repairs up to 12 mm (1/2 in) in depth per layer.
Application Details:
- Surface Preparation: Concrete must be fully cured (28 days), with a minimum hardness of 24 MPa (3,500 psi), and prepared to ICRI CSP 3 or 4 via shot blasting. Steel surfaces must meet SSPC-SP10 standards. All surfaces must be clean, dry, and free of contaminants.
- Mixing: ALSAN RS CATALYST POWDER must be added to the resin just before application. The amount of catalyst varies with temperature (2% at 20–35°C, 4% at 10–20°C, 6% at 0–10°C).
- Application Temperature Range: 0°C to 35°C (32°F to 95°F).
- Humidity Consideration: Substrate temperature must be at least 3°C (5.4°F) above the dew point to avoid condensation.
- Application Method: Apply using a roller or flat squeegee to a wet film thickness of 560 µm (22 mils).
- Coverage: Approximately 340 ft² per 17.65 L (18 kg) kit at 22 mils wet film thickness, or 3,775 ft² per 196 L (200 kg) drum.
- Pot Life: 15 minutes at 23°C (73°F).
- Rainproof Time: 30 minutes.
- Full Cure Time: 3 hours at 23°C (73°F).
- Repair Use: For repairs larger than 305 x 305 mm (1 ft²) and deeper than 12 mm (1/2 in), multiple layers must be applied, each not exceeding 12 mm in depth. There is no limit to the number of layers, but each must cure before the next is applied.
Special Notes:
- ALSAN CIVIL P70 is not UV stable and is intended for use beneath other system layers.
- The product must be stored indoors between 0°C and 25°C (32°F to 77°F) and has a shelf life of 12 months in its original container.
- Tools and equipment should be cleaned with ALSAN RS CLEANER immediately after use.
- For applications below 0°C (32°F), consult a SOPREMA representative for guidance.
- A peel test (ASTM D4541) is recommended on steel substrates to confirm adequate adhesion.
- The product has a Shore D hardness of 70 after 7 days and demonstrates strong adhesion to both concrete (>1.5 MPa) and steel (>2 MPa).
ALSAN CIVIL P70 is a critical component in SOPREMA’s PMMA-based waterproofing systems, offering excellent adhesion and fast curing properties, making it ideal for time-sensitive infrastructure projects.
