Dr. Fixit Extensa R is typically used as a waterproofing membrane for new roofs, foundations, plaza decks, bridge decks, interior and exterior walls, walking decks, steel or wood beams, and a wide range of specialty waterproofing applications.

Description

Dr. Fixit Extensa R is typically used as a waterproofing membrane for new roofs, foundations, plaza decks, bridge decks, interior and exterior walls, walking decks, steel or wood beams, and a wide range of specialty waterproofing
applications. However it can also be used as remedial waterproofing for all types of roofing materials, without tearing off the old ones. Thus Dr. Fixit Extensa R is a waterproofing solution for the entire building envelope and beyond.

Installation
Surface preparation is generally limited to pressure washing or compressed air cleaning for Dr. Fixit Extensa R, to bond to the substrate. The product system can be spray applied quickly at 100 sq.m. per hour with a special spray gun, reducing crew size and job time. Although Extensa R is UV stable, weather resistant, but is black in color and hence it is typically over - coated with an energy efficient white acrylic coating. Extensa R is lightweight and hence can be applied directly over an existing roof system, eliminating the need for wasteful and costly tear-offs.

Installation - Roof Restoration Process
Surface Prep aration
<li> All surfaces must be pressure washed or clean with compressed air, then allowed to dry, free of loose materials, oils, form release agents and other contaminants. Any damaged areas of existing substrate or old roofing
membrane should be properly patched or sealed with appropriate repair materials that will bond to the existingsubstrate and will accept Dr Fixit Extensa R, to bond well to it. Dr Fixit has a range of repair materials that can be
appropriately used to prepare damaged substrates well.</li>
<li> Priming is recommended on some substrates prior to application of Dr. Fixit Extensa R. Consult Dr. Fixit Technical Team for this Dr. Fixit Extensa Prime shall used for asphaltic based substrates as well as for concrete
to create a superior bond with the Extensa R membrane. An EPDM primer is used for EPDM and PVC substrates.</li>

Application
<li>Dr. Fixit Extensa R is applied through special spray equipment. It cannot be sprayed through other types of
commonly available sprayers without damage to the sprayer or to the product. Dr. Fixit Extensa R can be
sprayed at a rate of 1.5 litres / sq.m. or, approximately 13 sq.m. per a 20 litre pail to achieve a dry film thickness
of 1mm. Coverage may vary depending on the profile and texture of the substrate it is being applied and in
general application conditions. It is best to begin spraying at the lowest side of the roof and work towards the
higher points, to prevent the accelerator from running over clean substrate areas prior to spraying over them.</li>

Detailing
<li>If required, use a quick setting repair mortar like PAGELR 20/20 as flashing and over-spray with Dr. Fixit Extensa R membrane system.</li>

Warnings and Hazards
<li>Although minimal odor and mist exists while spraying, wear a respirator in areas of limited ventilation. Otherwise a basic nose mask and goggles are recommended while spraying. Avoid eye contact with the products. Refer to
MSDS for specific warning and product information.</li>
