RX ROOF REPAIR

Rx Roof Repair should not be applied to unprepared surfaces including but not limited to those that are dusty, oily, mildewed, heavily chalked, blistered or otherwise structurally unsound. Asphaltic or bitumous substrates may cause discoloration or bleeding of the mastic. It is recommended that the use of Tropical’s 996 Eterna-Sil Premium Bleed Blocker be used to mitigate this discoloration and bleeding. Refer to Data Sheet for complete details.

Rx Roof Repair Eterna-Sil Perma-Patch can be applied over properly prepared surfaces that exhibit ponded water, however, The National Roofing Contractors Association (NRCA) considers ponding water an undesirable non-standard roofing practice and recommends that all roof systems be designed and built to ensure positive drainage. (See the NRCA Roofing and Waterproofing Manual). Please contact Tropical Roofing Products Technical Department for any specific questions regarding the application of this product.

For ideal application all surfaces to be repaired must be clean and paintable. Rx Roof Repair may be applied to damp surface, but any standing or ponding water should be removed. It may be necessary to power wash and/or prime to enhance adhesion. See application specification for more details.

Rx Roof Repair can be applied by trowel, stiff brush or gloved hand. For cold weather application, keep material stored above 65°F (18°C). Do not apply to substrates with temperatures below freezing or above.

Apply Rx Roof Repair to ensure a uniform build and thorough coverage typically applied in one application. If applying in multiple applications, allow adequate time between each application for the sealant to cure before applying additional material. Final cured thicknesses must be free of voids, pinholes, cracks or blisters. Refer to Data Sheet for complete details.

Rx Roof Repair is UV stable. No top coat is required. It is not intended to be painted or covered over with any product other than Tropical Roofing Products’ Silicone Roof Coatings.

Recommended 25-35 linear feet at a minimum thickness of 1/8”. Application rates are job specific and will vary by surface, porosity, and job conditions. Additional material may be required.

Cleanup of equipment containing uncured material may be accomplished by cleaning with mineral spirits, alcohol, or toluene. DO NOT USE water.
