GacoPro Roof Coating, a professional grade, 150% elastic, 100% silicone roof paint for flat and pitched roofs, that can be applied-year round and guarantees protection and waterproofing for 20 years.
GacoPro Roof Coating is a single pack, moisture cured liquid coating that can be applied directly to the surfaces listed below without the need of a primer:
- Aged/weathered felt
- Asphalt
- EPDM
- Thermoplastic Polyolefin (TPO)
- Most single ply membranes
- Asbestos
- Steel
- Plastisol
- Concrete
- Lead
- Fibreglass
- Sprayed polyurethane foam
- Tar and gravel
- Modified bitumen
- Built-up systems (BUR)
- Cap sheet
- Torch down
- Most existing roof coatings
- WPB plywood (apply 3 coats)
GacoPro Roof Coating is easy to apply by brush, roller or spray and produces a protective coating to permanently protect against leaks, constant ponding water, and the damaging effects of severe weather making it also ideal for valleys, gutters, channels etc. on roofs.
Refurbishing a roof or gutter with GacoPro Roof Coating is economical, causes less disruption, is fast to carry out, and is environmentally friendly and energy saving. In many cases where a roof would otherwise require total removal and reinstallation GacoPro Roof Coating is able to extend the life of the roof by a minimum of 20 years.
Furthermore, using GacoPro Roof Coating in Solar Reflective White will reflect over 85% of the sun’s rays, drastically reducing damaging thermal shock (expansion/contraction) which will in turn, further extend the life of the roof and help to reduce building cooling costs, saving energy.

Features & Benefits
- No reinforcing fleece or mesh required saving material cost, labour cost and installation time. Gaco Roof Tape or Gaco Liquid Roof Tape can be used to fix any cracks, corners, upstands, etc. prior to application
- No primer required over most surfaces again saving material cost, labour cost and installation time
- Can be applied in temperatures as low as 1℃ and up to 45℃ making year-round application possible
- The single pack formulation makes it fast and easy to apply by roller, brush or spray
- Available in two colours (Light Grey and Solar Reflective White) these can be used as contrasting colours on each coat to aid application by ensuring correct coverage
- Totally waterproof after just 2 hours, even under permanently ponding water
- The seamless finish resists the growth of moss and algae keeping the roof cleaner for longer
- Remains flexible in all weather conditions and temperatures
- Outperforms other industry Acrylics, Urethanes, & Bitumen coatings
- The Solar Reflective White finish reduces roof temperatures up to 85% which in summer will help to reduce building cooling costs, saving energy
- 20 Year factory warranty on product
- Very competitive price per square metre
Complimentary Products
- GacoFlex GacoWash - A concentrated cleaning solution for roof membranes and existing waterproof systems. It is specially formulated to remove tough dirt, pollen, mildew and fungus before the application of GacoPro Roof Coating is carried out.
- GacoFlex E5320 2-Part Epoxy Primer/Filler - A water based, multi-purpose primer offering excellent adhesion to most surfaces including metal roofs, metal flashing, other coatings, wood, masonry, single-ply membranes and more, and helps improves the adhesion of GacoPro Roof Coating.
- Gaco Roof Tape - A self-adhesive seam tape made of cross-linked polymers of butyl and E.P.D.M. rubber, coated on fleece backing. Gaco Roof Tape maintains its elasticity and splice integrity when subjected to severe ultraviolet rays, thermal shock, ponding water, and extremely low temperatures.
- Gaco Liquid Roof Tape - A thick, high-build, rubber-like liquid comprised of 100% silicone and microfibers. The unique properties allow it to replace traditional rubber and mesh seam tape when used in conjunction with GacoPro Roof Coating.
- GacoFlex SF2036 WalkPad - A stay-put solution for creating highly visible rooftop walkways. It is an exceptionally durable, silicone-based, solvent-free coating that is combined with a reinforcing agent to provide exceptional durability and resistance to traffic and tears.
- GacoFlex WalkPad Granules - Roofs become slippery when wet and extreme caution should be exercised when accessing any roof area for maintenance. GacoFlex WalkPad Granules complete the GacoFlex SF2036 WalkPad walkway system providing a traction enhancing textured surface.

| Applied Coverage: |
9.3m² per 3.8L to yield 280 microns DFT on a smooth surface. Coverage rate may decrease on textured or rough surfaces, and more coating will likely be used on first coat than on additional coats. Smooth roofs can be completed in 2 coats, lightly textured surfaces often require 3 coats, and heavily textured surfaces may require 4 coats to achieve a final 560 microns DFT. |

Application
Primer
None normally required. If roof has been patched with any asphalt or black tar-like products within the last 12 months, a coat of GacoFlex E5320 2-Part Epoxy Primer/Filler is recommended to prevent bleed-through staining on the final coats.
To verify adhesion, use the GacoPro Adhesion Test Kit, which provides results in just 24 hours. If the test reflects poor adhesion, prime all surfaces with GacoFlex E5320 2-Part Epoxy Primer/Filler according to label directions.
Mixing
Mix before application to assure uniform colour and consistency.
Power mixing is recommended.
Application
Apply by roller or brush as received. Airless spray requires air driven pump with ratio no less than 65:1.
For cold weather application, keep material stored above 65°F (18°C). Ensure that previous applications of GacoPro are clean, dry and well cured before recoating.
Cleanup
Application tools and equipment can be cleaned with GacoFlex Silicone Solvent or 100% Pure Mineral Spirits. DO NOT USE WATER OR RECLAIMED SOLVENTS.
Maintenance
Once a container of GacoPro is opened, the curing process has started. Use the entire product on your project if possible. Close can lid to store product. Some skinning will occur. For next application, remove ‘skin’ stir well and apply. Allow any remaining product in the container to solidify and dispose of in the proper manner.
Roof structures may settle over time. A periodic inspection of your roof, which includes transition areas, flashing, vents and skylights, is recommended. Keep drains cleared at all times.
Roofs become slippery when wet. Use extreme caution. Consider use of GacoFlex Walkpad for walkways in areas of regular maintenance traffic.
Do not recoat GacoPro with acrylic, urethane or Hypalon coatings. Recoat cleaned GacoPro only with more GacoPro.
Dry Time
Allow the first coat to dry for 3 to 12 hours. Apply second coat as soon as the first coat can be safely walked on.
