Our Product Line

Drythane is a 100% Solids, two component polyurethane coating system that contains no volatile organic compounds (VOC) or solvents, specifically formulated as a seamless and tough waterproofing membrane.

Drythane is a 100% Solids, two component polyurethane coating system that contains no volatile organic compounds (VOC) or solvents. It has been specifically formulated as a seamless and tough waterproofing membrane. It comprises of the PIV Primer along with a choice between (or combination of) three liquid-applied fused layers — Drythane Standard, Plus, and Aliphatic.

PIV Primer

A 100% solids damp tolerant, two-component polyurethane primer with excellent adhesion to damp and dry concrete. It penetrates and reinforces concrete surfaces, seals to prevent out-gassing and pin-holing, and also reacts with moisture present in the concrete. With our revolutionary coating, futureproof the house of your dreams!

Drythane Standard

High performance, standard workhorse product. Tough, impermeable membrane totally unaffected by immersion in water. Elastic membrane with 2.50 mm crack spanning capacity.

Tensile Strengthover 2500 Psi

Hardnessabove 65 ShoreD

Elongationmore than 90%

Drythane Plus

Paint roller applied Polyurea Hybrid with very high elongation for cold climates, flexible and crack prone surfaces. Very high crack spanning of 10 mm.

Tensile Strengthover 2500 Psi

Hardnessabove 50 ShoreD

Elongationmore than 350%

Drythane Aliphatic

Colour fast, decorative finishes. White colour for high solar reflective index and reduction in surface temperature of roofs.

Tensile Strengthover 2500 Psi

Hardnessabove 60 ShoreD

Elongationmore than 85%

All four products are environment friendly with zero solvent content or odor during application. They are non-toxic and suitable for water immersion. Since they have no solvent, the wet film thickness is equivalent to the dry film thickness and so only half the quantity is required (as compared to other solutions) for the same thickness. With a very fast curing process, Drythane can be used/water immersed in 24 hours. The final product can be left uncovered and unprotected without risk of damage from normal use. Screed or tile covering is optional only for aesthetics purposes.

Revolutionary Properties

Seamless Membrane & Easy to Apply

Liquid polyurethane applied as a seamless, monolithic membrane to a thickness of 1.50 – 2.00 mm. Simply mix two components, pour the mixture, and spread it using a paint roller to a specific thickness in one or two coats. A special damp-tolerant Polyurethane Primer will seal the concrete prior to application of the main coat thereby allowing application even in high humidity environments.

Fully Impermeable to Water

Drythane is completely impermeable to water and has very low water absorption in continuous immersion with a saturated weight gain of less than 0.60% as per Procedure 7.4 (Long Term Immersion) of ASTM D 570. Further, it is highly resistant to a wide variety of Acid, Alkali, Salts, etc. These unique properties allow it to be used for continuously damp or wet applications such as rooftop gardens, ponds, storage tanks, swimming pools etc.

Tough and Durable, Long Service Life

When cured, Drythane is a very tough, durable, elastomeric membrane with a tensile strength of more than 2,800 Psi and a hardness of 65 Shore D! As it cannot be damaged during normal use, you have no need for reinforcement or protection covering through masonry. Further, it resists degradation from sunlight (UV), rain, heat & cold weather. Our high performance membrane provides a long service life of more than 25 years.

Crack Spanning & Elastic Nature

Drythane is an elastic membrane with over 90% elongation. For cold climates, flexible surfaces, and substrates prone to cracking, we offer Drythane Plus with an elongation of over 350% . Additionally, it is unaffected by temperature cycling and will span cracks in concrete up to 2.50 mm. Using 0.50 mm Drythane Plus as a base coat with 1.00 mm Drythane as the top coat will increase the crack spanning of the combination to over 10.0 mm+

High Adhesion

Drythane bonds strongly to the substrate. Thus, in pull off tests, the break takes place only within the concrete and not at the interface. Unlike sheet applied materials, liquid water cannot possibly intrude under our coating. Adhesion is usually an indicator of the service life — higher the adhesion, longer is the service life.

Optional Aliphatic Reflective Coat

Insulation from heat can be achieved by greening the roof (with drainboard, soil and grass) after applying our products! However, if a green roof is not desired but you still want to reduce indoor temperatures, you can simply apply an optional aliphatic, colour fast, and heat reflective top coat.
