PC Sealcoat® MP

High-Performance Hybrid Micro silicate Polyurea Waterproofing & Anti-Corrosion Coating

PACKAGING

PC Sealcoat® MP available 20 Kg pails (19 Kg Part A , 1 Kg Part B)

PC Sealcoat® MP is a high-performance micro-silicate polyurea designed to deliver long-lasting, seamless waterproofing. It forms a durable, elastic, monolithic membrane without joints or seams, providing reliable protection over time. Engineered for industrial metal roofs and metal surfaces, it is also compatible with concrete and marine structures exposed to chemicals, acids, alkalis, and salt contamination. PC Sealcoat® MP offers excellent adhesion to diverse substrates, including concrete, metal, tiles, insulation foam, and asphalt membranes. Cold-applied and self-leveling, it achieves high film thickness in a single coat, making it ideal for both new construction and refurbishment projects that demand rapid return to service and enduring performance.

SURFACE PREPARATION

Proper surface preparation is essential for the long-term performance of PC Sealcoat® MP. All substrates must be fully cured, structurally sound, clean, dry, and free from dust, oil, grease, curing compounds, laitance, or any contaminants that may affect adhesion. Weak or loose materials must be removed mechanically. Surface irregularities, cracks, voids, and honeycombs should be repaired and levelled using suitable repair materials prior to application.
Priming is critical to ensure strong adhesion and to prevent air entrapment or outgassing. The choice of primer should be based on the type of substrate and its moisture condition. Porous, absorbent, or uneven concrete surfaces must be primed thoroughly before applying PC Sealcoat® MP. Metal surfaces should be mechanically prepared, preferably by abrasive blasting, to create a clean and roughened surface. Ceramic or tiled surfaces must be stable, with no loose tiles or empty joints, which should be properly filled before priming.

APPLICATION PROCESS

PC Sealcoat® MP is supplied as a pre-measured two component system to ensure correct mixing ratios. Both components should be conditioned to approximately room temperature before mixing. The first component should be mixed slowly using a mechanical mixer to achieve a uniform consistency without introducing air.
The second component is then added gradually, and the combined mixture is mixed at low speed until a homogeneous material is obtained. The sides and bottom of the container should be scraped during mixing to ensure complete blending.
After mixing, the material must be applied immediately. The mixed product is poured onto the prepared and primed surface and spread evenly using a notched trowel, spreader, or roller. For improved surface finish and uniform thickness, spiked shoes and a spiked roller may be used. The membrane cures rapidly, and the final curing time depends on ambient temperature, substrate temperature, and material temperature. In most cases, the required membrane thickness can be achieved in a
single coat. If a second coat is required, it should be applied within the recommended recoat window after the first layer becomes touch dry. Once fully cured, PC Sealcoat® MP forms a durable, elastic, and waterproof membrane ready for service.

CONSUMPTION

The consumption of PC Sealcoat® MP depends on the condition of the substrate, surface porosity, application method, and the required membrane thickness. The recommended standard application thickness is approximately 1.5 to 2.0 mm. At this thickness, the average material consumption is around 1.2 kg per square meter per millimeter of thickness. Actual consumption may vary depending on surface roughness, absorption of the substrate, ambient temperature, and application technique. For accurate estimation, a site trial is recommended prior to large-scale application.

SAFETY : Wear protective gear with PC Sealcoat® MP. Avoid vapors and contact with skin and eyes. Use gloves, clothing, and eyewear. Work in ventilated areas. Keep containers closed, away from heat, sparks, and flames. Store out of children’s reach. Follow safety guidelines.

CLEANING: Clean tools and equipment immediately after use with a solvent before the material cures. Once PC Sealcoat® MP sets, removal requires mechanical methods. Prompt cleaning is advised to maintain performance and extend tool life.
