Product Description

Elastathane 25 from Cromar rapid cure, one coat polyurethane liquid applied waterproof coating.

Coverage : 1.5 to 1.8kg per m2.
Weight : 25kg.
Life expectancy : 25 years.
Colour : grey.
Certification : CE Marked.
Coating : 1 coat.

Preparation : Clean substrate of loose material and jagged edges link stones etc, use a vacuum if possible, remember the better the surface the better the result and finish. You are only applying 1.5 to 1.8kg per m2 this is approximately a 1.2mm membrane. The surface is required to be dry, do not apply the primer if the surface is wet, if there are damp spots dry with heat gun or gas torch.

Carefully apply the primer evenly so as not to pond, the requirement of 0.2kg per m2.

Same day primer (Elasta Thane rapid cure PU primer) : Allow the primer to dry 2-4 hours depending on humidity and temperature. Applying the Elasta Thane 25 PU membrane immediately after the primer dries will give you perfect adhesion as it will be chemically bonded, if there will be delay on applying the main coat due to rain or any other reason then apply the next day primer (super seal primer) and wait 24 hours before the Elasta Thane 25 liquid PU application.

Next day primer (Elasta Thane super seal primer) : Allow the primer to absorb and cure, this will anchor itself to the substrate and will give you perfect adhesion as well as chemical bonding. Apply Elasta Thane 25 liquid membrane next day/week/month - this primer has great memory and will maintain its chemical bonding long after the next day primer has been applied. Elasta Thane cannot be coated until after 12 hours.

Please note where there are weak areas, joints, upstands or corners etc use the elasta tex scrim and apply wet on wet. If there are open joints or gaps then apply Cromar polyflex PU sealant, this is required after the primer application and before the main coat.

Questions & Answers


Can you put thinners in the elastathane 25 to make it more playable when the temperature is colder


Unfortunately not, that is not an option with this material.


Can this product be applied to a metal box gutter after priming.


I am afraid the suppliers advise this is not suitable for use in a metal box gutter, you may be better off with a product like Acrypol.
