Why Consider a Polyurethane Foam Roof Coating Application?

A polyurethane foam roof coating can extend the life of your roof by 10 years or more.Sprayed Polyurethane Foam deteriorates quickly when exposed to the sun's UV-rays. It needs to be coated with a UV protective coating immediately after installation. Elastomeric roof coatings are the roofing material of choice for this application.
Typically, polyurethane foam roofs have 1-2 inches of foam sprayed over an existing roof such as metal, built up or modified bitumen. It is then topcoated with an elastomeric roof coating to provide a watertight, UV protective membrane.

Polyurethane foam must be recoated every 10 years or so as a preventive measure.

Polyurethane Foam Roof Restoration Process

Cleaning and Surface Preparation

The entire polyurethane roof was thoroughly washed using a 3,000 psi pressure washer. A biodegradeable degreaser was used to ensure a clean surface. All seams, flashings and penetrations were carefully sealed to render the roof watertight.

Priming

Priming ensures a good adhesion between the polyurethane foam roof surface and the
elastomeric coating.

Top Coating

At least 30 dry mils of elastomeric roof coating is applied on the entire polyurethane foam roof in 2 coats.

Winter season leads to roof leaks and EPDM is a ultimate repair for it

After every winter season, all roofs needs inspection for leaks. Winter season always leads to roof leaks and the solution for it is to repair or replace roof. There are a number of factors that may lead to roof leaks so there is not a simple answer. One of the most common causes of leaking roofs in winter is clogged or improperly installed gutters. This will cause water to overflow over the back and leak along the inside walls and inside the home. In addition, flue pipes inside of a chimney may cause water to leak if they are not properly aligned. Improperly installed or defective siding and windows are among other common causes for roof leaks. When a roof leaks after heavy, wind-driven rain, it is usually caused by a problem with the windows or siding. During the winter, a roof leak along the inside walls or basement is most commonly caused by an ice dam.

EPDM Coatings have Liquid Roof and Liquid Rubber which are the most suitable products for stop the leaking roofs. Metal Roofing magazine has awarded EPDM, top 10 products of 2009.

Physical Properties of Liquid Rubber

The physical properties of Liquid Rubber(R) are typical of its EPDM chemistry. The outstanding characteristics include:

Extreme high resistance to penetration of water. Ultra Violet and Ozone stable. Excellent long term aging properties.

1. Very broad temperature tolerance range (from 300 degrees F to minus 62 degrees F). Acid and alkali resistant.
2. Withstands ponding water even when not cured.
3. Spreading Rate A 20 mil dry film will result when liquid is applied at the rate of 42 sq. ft per gallon on a smooth surface.
4. A rate of 45 sq. ft allows for average roughness.
5. Weight/gallon 8 pounds (mixed).
6. Tensile 680 psi.
7. Elongation 180-200%.
8. Brittle Point -62 degrees F.

Application of Liquid Roof

Liquid EPDM being sealed around AC/Vents. Notice its ability to be applied on both vertical and horizontal surfaces without running.

Roof Repair Materials

There is a long list of materials which are commonly used in roof construction; it includes metals, plastics, rubbers, fibers, glass, wood, rocks, ceramics etc. But building just a roof is not enough, its proper finishing and maintenance is something which is of foremost importance. That is why; it’s the need of time that the roofing contractors must also be familiar with the concept of roof coatings.

Roof coatings are a monolithic and fully adhered fluid applied over the roofs. If applied properly, it helps to extend the life of the roof, ultimately saving the cost of re roofing. It has many outstanding features which makes it an important component of roof construction and finishing. When applied over the roof, it acts as a top layer over the underlying roofing system. Its high elasticity allows it to expand and contract back to its original position. But being the top most layer asks for tolerating a lot of environmental effects like UV and infrared, temperature extremities like rain, hail and the physical damage caused due to these factors. Therefore the roof coatings are specially manufactured keeping in view all these factors so that maximal protection is delivered to the roof from these roof weakening causes.

Application Instruction for Liquid Rubber

Liquid rubber is far superior to other forms of adhesives, and is able to fill in moderate sized pipe leakages as well as cracks. It can be bought in a clear liquid form as well as in a silicon-type version. If you are looking to purchase liquid-rubber for your home, you should look for the stuff that has "EPDM" on the label. This type of liquid rubber has extra adhesive power and will be better than most other types of liquid-rubber.

There are Following Step involve in Liquid Rubber Application:

• Surface preparation
• Coverage:
• Mixing Directions:
• Application:
• Temperature and Cure Conditions:

Surface to be coated with Roof Coatings 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 EPDM Liquid Rubber®.

EPDM Liquid Rubber® 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.am-5:30 EST.

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

EPDM Liquid Rubber® 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. EPDM Liquid Rubber® will provide long term protection even under extreme exposure conditions.

Commercial and Industrial Applications of Liquid EPDM

Marine Uses. 

(Product -9911 Ship Shape) Liquid EPDM rubber coatings can be effectively used on ships, boats and barges. because of their inherent characteristics: i.e. Ultra Violet stability, salt resistance, excellent water resistance, low and high temperature tolerance and flexibility.9911 Ship Shape is designed specifically for marine use.

Fish ponds 

Liquid Rubber can be used for repairing fish ponds. It can be use for both commercial and residential purpose. The concrete must first be thoroughly cleaned and dried. If the concrete is porous it should first be primed with a primer. The EPDM rubber is harmless for fish.
