MARISEAL 250 AQUA | Liquid-applied, polyurethane waterproofing membrane Water-Based

The MARISEAL 250 AQUA is a highly durable, water-based, polyurethane membrane specifically designed for long-lasting waterproofing. Here are the details regarding its composition, advantages, usage, technical data, application guidelines, and safety measures:

Product Description & Advantages

Composition: Comprised of flexible, water-based polyurethane resins that create a seamless, jointless, and 100% waterproof membrane.
Key Features:
- Cold applied and curing.
- High crack bridging ability.
- Maintains mechanical properties in extreme temperature ranges (-40oC to +90oC).
- Offers water vapor permeability.
- Superior adhesion without additional anchoring.
- Can withstand pedestrian traffic.
- Easily repairable even if damaged.
- Low VOC content (< 100g/l).
- Cost-effective solution.

Uses & Consumption

Applications: Rooftops, balconies, terraces, wet areas (bathrooms, kitchens), polyurethane foam insulation protection, and concrete constructions (bridge decks, tunnels).
Consumption: 1.4-2 kg/m² in two or three layers. Consumption may vary based on surface porosity, temperature, and application method.

Colors & PUD Technology™

Colors: Available in white, grey, and brown-red.
PUD Technology™: Utilizes innovative PUD Technology™ by MARIS POLYMERS SA, offering high-level properties of solvent-based products in an eco-friendly, water-based, low VOC product.

Technical Data

Physical Properties: Elongation at Break, Tensile Strength, E-Modulus, Tear Resistance, Water Vapor Permeability, Resistance to Water Pressure, Adhesion, Hardness, and more.
Application Data: Emphasizes surface preparation, repair of cracks/joints, priming, waterproofing membrane application, curing times, and temperature constraints.

Application Instructions

Surface Preparation: Requires clean, dry, and sound surfaces free from contamination. Surface irregularities need to be smoothed, and proper slope as per European Construction Codes is necessary.
Crack & Joint Repair: Detailed steps for sealing concrete cracks and expansion/control joints before application.
Priming & Waterproofing: Instructions on priming different surfaces and applying the waterproofing membrane in layers, reinforcing with fabric in problem areas.
Finishing: Recommendations for top-coats for color stability and enhanced abrasion resistance.
Packaging & Storage: Details on storage conditions, shelf life, and precautions to protect against frost.

Safety Measures
