Manual Application Instructions For Liquid Roof

Surface to be coated should be clean, dry and structurally sound. Fasten loose areas with adhesive (contact cement) or pop rivets. Oil or wax must be completely removed with solvent. Remove loose portions of existing coatings and brittle caulk with scraper and wire brush. Whatever still has good adhesion may remain to be recoated. Rusty or pitted metal should be wire brushed to remove loose oxide. Tightly adhering corrosion may be directly coated with Liquid Roof.

Asphalt based aluminum coatings should be removed as much as possible by wire brush or abrasive disc. Roof cements should be removed and replaced with butyl caulk where necessary. Repair torn rubber with adhesive Butyl Tape. A rubber patch may be applied over torn area if desired. Remove chalk from white rubber membrane by brushing with a detergent solution followed by a water rinse or working surface with a stiff brush. Smooth metal or plastic surfaces should be roughed up to improve adhesion of Liquid Roof®. A deglossing solvent may work on some plastics.
Coverage:
Liquid Roof® will cover up to 46 square feet per gallon on a very smooth surface. Normal coverage is 40-42 square feet per gallon on an average substrate. The required 20 mil film thickness will be achieved when the above spreading rate is used. If you are uncertain how to calculate the amount of material you will need, please contact EPDM Coatings at (866-311-3736) M-F 9:00-5:30 EST.
Mixing Directions:
liquid roof application direction The container is under filled to allow for the addition of the pre-measured catalyst that is included. A drill, and a mixer (shown below) will be needed to incorporate the catalyst. For a 1 gallon can a short mixer will suffice. For 4 or 5 gallon pails you MUST use a long shaft mixer.

The catalyst will be inside the box for 1 gallon and 1 gallon repair kits. The catalyst will be located under the lid in 4 and 5 gallon pails.

Mix rubber material in can/pail until uniform; center mixer shaft in pail or can and begin mixing until a vortex is formed. Slowly pour all of catalyst into vortex. Move mixer up and down and in a circular motion for 2-3 minutes until all portions of can/pail are uniformly mixed
Application:
By brush, roller or squeegee. A combination of methods might be most effective. For example, on a flat roof, pour a serpentine bead of material, distribute with squeegee, finish with a short nap roll to press air out of cracks and even out wet film. Product will self level when sufficient material has been applied. Working time is 4-6 hours depending on temperature. A single application of Liquid Roof is preferable to multiple coats. Apply with brush around flashings and edges using long, slow strokes. On flat surfaces, material can be poured, spread with a squeegee and then evened out with a short nap roller. Touch-ups may be applied as desired after initial film has cured and surface is first wiped with solvent.
Temperature and Cure Conditions:

Liquid Roof® may be applied at any temperature that permits it being spread onto the surface. It will waterproof immediately upon application. The solvent will evaporate at a rate governed by temperature but will not be affected by relative humidity. Exposure to freezing temperatures before cure has taken place will not damage the film. The time necessary to reach cure should not be a concern as this process will occur automatically. Exposure to sunlight will accelerate the curing process. The final film properties of the cured membrane will be the same regardless of the time required to achieve cure. Liquid Roof® will provide long term protection even under extreme exposure conditions.

Roofing Facts which all of us need to know

- Metal roofing panels, especially darker colors, respond to temperature change by expanding and contracting. This causes the fastener holes size to increase, and can cause leaks.

- Panels screwed into metal roof rafters will experience less thermal movement.

- Galvanized factory-finished roofing panels and flashing materials, used in housing construction, require specific dimensions of panel and flashing overlapping and watertight sealant application between the product overlaps according to the manufacturer's recommendations.

- Exterior coatings and sealants applied to roofing panels and flashings dry out and fade prematurely, because the ultraviolet rays of the sun in sunny areas are intense. If the coatings and sealants are not maintained and replaced before they dry out, they will crack and allow water infiltration.

- The driving tropical rains from all different directions and can be challenging for roofing materials that use an overlapping system of corrugated panels to keep moisture out. When rain comes at a building from almost sideways, it forces water under these metal panels that eventually ends up on the roof sheathing installed on top of the roof rafters.

- Many structures do not have a roof sheathing installed and the metal panels are screwed directly into the roof rafters. The spacing in between the roof rafters is open to the interior ceiling of the living areas below and any water infiltration ends up on top of the materials installed for the living area ceilings.

- If the interior ceiling material selected was drywall or other porous type materials, then eventually, with sufficient water infiltration, those areas of the ceilings will appear clouded or sometimes the surface will peel off.

Roof Sealing

High-strength elastic roofing and sealing material consisting of at least one bonded fabric layer of organic material, optionally at least one further bonded fabric or bonded-fabric material layer of inorganic material, and a coating of bitumen on both sides, where the bonded fabric layer(s) is (are) impregnated with the bitumen, and where the bonded fabric of organic material has a certain area weight and a certain residual deformation after previous elongation. The bitumen coating optionally can be made elastic by the addition of modifiers with sufficiently low glass conversion points.
The sealant can be used for installation and maintenance of a roof made of shaped boarding or roof tile:
• in places of isolation joints between open-ended exit points and roof sheets;
• under ridgy planks and joints of a tent shape roof;
• under a snow shield on a roof;
• when installing the furring;
• at lap seams;
• at trough joints;
• at a joint of a trough and a drainpipe;
• at a trough end;

Ensure roof tiles are clean and dry prior to application of roof sealer. Apply roof sealer with a sprayer unit, brush or roller. The first application must be applied to the surface and allowed to dry past tacky prior to applying the second coat. Avoid application in strong, direct sunlight - do not apply if rain is likely within 4 hours of application.

Roof Sealers are bright white, reflective, elastomeric roofing solutions for roofs that are not yet ready to be torn off and are capable of being restored back to their original quality. EPDM, Modified Bitumen, Metal Roofs, Single-Ply, Polyurethane Foam, Smooth Built Up, or even Gravel Built-Up, we have a roof coating that can repair and restore your roof. Our roof coatings can even repair metal roofs to good as new condition.

Flat Roof Leaks Detection

During a home inspection, roof leaks are typically discovered by my direct observations and then confirmed by utilizing moisture meters on the sheathing below. But if I detect a moist area and the roof sheathing is not visible from below (such as a finished cathedral ceiling or a ceiling below a living area) the exact area of the leak can not be determined. Most homeowners have the misconception that moisture stains are caused from leaks that are directly above a wet area. It’s just not true in most situations. On gable roofs, some leaks occur at the ridge line area and cling to the rafters for quite a distance until it finally drips onto the ceiling below. In order for anyone to locate the exact area of the leak, the damaged ceiling must first be removed. This removal is necessary in order to “visualize” the exact intrusion point at the underside of the roof sheathing. Now before any of the ceilings can be removed, all the furniture must be removed from below the affected area. Then the floor must be protected from the falling debris and possibly requiring a scaffold system. All of this can cost hundreds and even thousands of dollars! Infrared Thermography is an invaluable non-destructive and non-contact tool that can detect and pinpoint hidden roof leaks without even damaging the interior or exterior surfaces. Then once I pinpoint the problem area, minimum surface areas can be removed in order to make the necessary repairs.

I prefer to perform all exterior roof inspections in the early evening hours. In order to perform the infrared inspection correctly, I require solar heating of a hot sunny day to heat up the roof surface. Then in the early evening (after the sun goes down), the roof starts to cool allowing my infrared camera to be able to detect obvious thermal differences if there are any moisture intrusions within the roof surface. Thermal properties of water are very unique (high thermal capacity), allowing water to be thermally observed on the surface and on the underside of roofing materials. If water is actively seeping into the cavity of a roof surface, the dry roof insulation will cool much faster than the soggy wet roof insulation, making it possible for me to observe the thermal differences.

Durability of Liquid Roof Coatings

Liquid Roof is a liquid elastometric copolymer rubber coating that has excellent elongation, tensile strength, UV resistance and durability. Cures to a hard white or light gray rubber heat reflecting coating!
The material factors that influence durability are complex and related to the chemical composition of the liquid constituents, the thickness of the system as well as the type and density of the reinforcement. Central to the long-term success of liquid-applied waterproofing systems is preparation of the substrate and achieving the required membrane thickness.
Typically, manufacturers only guarantee their products when applied by approved and trained installers. This is not surprising as standards of application by squeegee, roller, brush or spray are very demanding; layers are measured to tenths of a millimetre and avoidance of air holes is essential. The weather conditions in which the liquid is laid are critical as are the times between application of coats.

Other key durability issues include:

• Ensuring the substrate construction and condition is free from material which may impair the bond, create thin spots or penetrations in the coating.
• Provision for moisture removal of damp substrates.
• Ensuring there are no point loads on the roof.
• Specifying a system suited to the expected traffic load.
• Appropriate detailing at edges, verges, upstands, outlets, movement joints and day joints.

Liquid-applied coating that forms the waterproofing layer of an inverted roof should not require replacement during the life of the building, provided it is fully protected from ultra-violet radiation and extreme temperature variations by a loading layer above it.

By increasing the longevity of roof materials by using liquid roof coatings, organizations can avoid a substantial amount of roofing waste. There are an estimated 11 million tons of asphalt roofing waste going into landfills every year. Using liquid roof coatings can greatly increase the life of existing roof materials (particularly roof coatings) and reduce the amount of torn-off roofing waste going into landfills. The roofing waste that remains can be recycled into road mixes using existing processes already operating.
