WHAT SURFACES AND SUBSTRATES WILL GACOPRO AND GACOPRO ECO STICK TO?
GacoPro and GacoPro Eco 100% Silicone, liquid applied coating / membrane adheres to all clean, dry roofing substrates. Typically the most common substrates are aged Asphalt, Felt, Metal profile Roofs, Single Ply, EPDM, TPO, Concrete Roofs, Sprayed Polyurethane Foam, Fiberglass, Asbestos, Lead, gutters, valleys, WPB Plywood etc. GacoPro and GacoPro Eco are perfect for all Industrial, Commercial and Residential flat and low pictched roofing.
WHAT COLOURS DOES GACOPRO AND GACOPRO ECO COME IN?
GacoPro and GacoPro Eco are available in White and Gray. You may use either as first or top coat, white is the best from point of view of reflecting the sun's roof damaging UV rays during summer months.
DOES GACOPRO AND GACOPRO ECO CRACK FROM OVEREXPOSURE TO THE SUN?
No. GacoPro and GacoPro Eco do not break down and remain flexible at all times, in freezing and hot days, so it will not crack. When you use the Gaco systems white as the finish / top coat, as heat is virtually eliminated, expansion / contraction is practically eliminated, another reason why the Gaco systems last so long. GacoPro and GacoPro Eco's inbuilt flexibility copes with most structural movement also without damage.
WHAT HAPPENS IF I DON'T USE THE ENTIRE CAN RIGHT AWAY AND A SKIN FORMS?
Skinning is when the topmost layer of coating begins to cure in the can. Silicone is moisture-cured, so high heat and humidity will cause the product to skin. If surface skins, remove skinned material from container. To minimise skinning over several days, gently pour about 12mm layer of 100% mineral spirits on top of product until it is completely covered and do not move can until ready to reuse. When ready, pour off the white spirit layer, and stir can contents thoroughly with a power mixer. Keep container tightly closed between applications to minimise surface skinning.
CAN GACOPRO SILICONE FLAT ROOF COATING BE APPLIED WITH A SPRAYER?
Althougth it is fast to apply by roller; GacoPro and GacoPro Eco may be spray applied with appropriate spraying equipment and in appropriate conditions, i.e. large jobs with proper precautions taken re overspray etc. GacoPro must be sprayed without thinning. For details on suggested spraying equipment please contact us.
WHAT ABOUT FELT, ASPHALT, EPDM, TPO AND SINGLE PLY ROOFS?
GacoPro and GacoPro Eco may be applied to aged EPDM; TPO & Single Ply roofs but may require the use of a primer. 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 Gaco 5320 Primer according to label directions. Call for more information and specific recommendations.
CAN GACOPRO AND GACOPRO ECO BE APPLIED TO A ROOF DECK OR WALKWAYS?
CAN THE GACOPRO FLAT ROOF SYSTEM BE PRESSURE WASHED?
You can pressure wash GacoPro at a low pressure (below 2500psi). Do not aim nozzle of power washer close to the roof surface. You can also use a soft bristle sweeping brush and a garden hose.
WHAT IS THE COVERAGE OF GACOPRO AND GACOPRO ECO?
GacoPro: Because two coats are required, the coverage for the completed project is 1 U.S. gallon per 4m2 or 40 square feet. (You can use this rate to roughly figure out how many gallons you need to purchase). Nearest metric coverage rate is 40m2 per 5 U.S (aprox 19L). gallon per coat. Note: We recommend when pricing jobs to cover yourself by allowing 10 to 15% additional material for first coat, especially where surface is rough, cracked etc. Estimate your needs on basis of 5 U.S. gallon can covering 20 m2 (assuming two coats of same colour applied, but under normal conditions you would apply the grey as first coat and white as finish or visa versa.) Example: 100m2 roof. Requires 2 x 5 U.S. gall GacoPro Grey + 2 x 5 U.S. gall GacoPro White. (allow for waste or rough surfaces) Note: We recommend three coats on WPB Plywood.

IS THERE A MILDICIDE IN GACOPRO? DOES GACOPRO SUSTAIN MOULD OR MILDEW?

HOW DOES GACOPRO AND GACOPRO ECO COMPARE TO THE ACRYLIC ROOF COATINGS?
1. GacoPro and GacoPro Eco are long lasting and have a 20-year limited warranty. GacoPro and GacoPro Eco generally lasts as long as the substrate they are applied to. Acrylics, if they have a warranty at all, are covered for only 3-5 years. 2. GacoPro and GacoPro Eco can withstand PERMANENTLY ponding water. There are no acrylics that will stand up to the stress of permanent ponding water without bubbling or adhesive failure. 3. GacoPro can be applied in a wide temperature range 0c up to 48c (32-120 degrees F). Acrylics cannot be applied at temperatures below 12c or above 32c (55 degrees or above 90 degrees F). 4. All acrylics require a primer coat. GacoPro does not require any primer, sealer, fleece or patch compound. 5. GacoPro and GacoPro Eco do not require a recoat; reflect harmful UV rays and keeps your roof in good order. Silicone is inert, and does not degrade or wear away. Acrylics require a recoat every 3-5 years; making Gaco the better option every time.
ARE YOU SURE MY FLAT ROOF DOES NOT NEED A PRIMER COAT? DO I NEED TO PRIME METAL FLASHING OR OTHER METAL SURFACES?

GacoPro: the two coat system has a "built in" primer and the GacoPro Eco system uses a two part primer called E5320. Contact us to find out more.
