Yes, many Amchem products are designed for application over existing concrete or tile surfaces, provided the substrate is sound and properly prepared as outlined above. However, the compatibility of the Amchem product with the existing surface should be carefully assessed. Consider conducting a small-scale adhesion test in an inconspicuous area prior to full-scale application to ensure satisfactory bonding and performance.

Curing times vary depending on the specific product, environmental conditions (temperature and humidity), and the applied thickness. Refer to the product data sheet for the recommended curing time. Generally, light foot traffic is permissible after a partial cure, while full cure is necessary before subjecting the treated area to heavier loads or exposure to chemicals. Premature use may compromise the integrity and durability of the coating.

Drythane is a brand of solvent-free, 100% solids polyurethane waterproofing and coating solutions by Amchem Products Pvt(MADE IN INDIA & Green pro certified). Ltd. It provides elastic, seamless membranes for applications like Retaining wall, Water retaining structures, Podium, Sunken, roofs, swimming pools, and industrial structures.

Drythane is eco-friendly with zero solvents, non-toxic, and odorless during application. It offers a 25+ year service life, superior crack bridging (up to 8–10 mm with the Ultimate Combo), and requires half the material of solvent-based coatings due to equal wet and dry film thickness.

Drythane adheres strongly to concrete, metal, and other substrates. It’s suitable for roofs, walls, balconies, rooftop gardens, ponds, swimming pools, sewage treatment plants, and seawater cooling towers.

Yes, Drythane uses a damp-tolerant polyurethane primer that seals concrete, allowing application in high-humidity environments without compromising performance.

Drythane cures 3-4hrs, becoming usable or water-immersible after 48 hours. It can be left uncovered or optionally covered with screed or tiles for aesthetics.

The liquid membrane is applied in one or two coats (1.5–2 mm thick) using a paint roller. Detailed manuals, video guides, in-person training, and email/phone support are provided for applicators.

Yes, Drythane is non-toxic and safe for immersion in water, making it ideal for swimming pools, ponds, and drinking water tanks. It has low water absorption (<0.58% per ASTM D570).

Drythane is resistant to acids, alkalis, and salts, making it suitable for harsh environments like seawater cooling towers and sewage treatment plants.

Drythane is low-maintenance with a 25+ year lifespan. It can be left uncovered without damage from normal use. An optional aliphatic reflective coating can be added for heat insulation.

The Ultimate Combo combines a flexible base coat with a standard topcoat, achieving up to 8 mm of crack bridging, ideal for flexible surfaces or cold climates.

Drythane exceeds standards like ASTM-C836 (waterproofing), EN 1062-7 (crack bridging), and ASTM-D570 (water absorption). It’s manufactured in ISO 9001-certified facilities.

While DIY application is possible with provided guides and training, Drythane recommends professional applicators for optimal results. They connect users with trained applicators and ship materials/tools quickly.
