Application of liquid roof coatings

Application of Liquid Roof Coatings Steps

Application of liquid roof coatings is relatively simple. Most people can do it themselves. Here are the steps typically recommended for the job.

Make a Plan

As with any job, planning is important. Depending on the temperature variations in your area, you may need to plan to do the job well in advance. Ideally, you want to work when the temperature is expected to be between 65 and 75 for your own comfort. Working on roofs can be a very hot or a very cold job.

The temperature must be between 55 and 140 degrees in order for most products to cure. Colder temperatures are not generally recommending as the curing process is much slower and the ability to spread the material becomes more difficult.

You want to work on a day when rain is not expected. The product can waterproof immediately, but applying the material in pounding rain is not recommended. Pitting can occur. It takes 16-20 hours before the surface becomes dry to the touch. The full curing process takes another 4-10 days if the temperature is around 70 degrees.

Clean and Prepare the Surface

Ideally the surface should be smooth and clean. Any structural faults should be repaired beforehand. Structural faults include damaged or cracked roofing beams.

Asphalt-based and silicone-based caulking should be removed before the application of liquid roof coatings. Asphalt roofing materials and silicone-based rubbers are generally not compatible with EPDM rubber, although the use of a pre-coat can allow you to use the coating. Manufacturers vary in their recommendations concerning the pre-coat.

Holes and low spots should be filled with non-silicone based caulking to even out the surface. Although the coatings are resistant to pooling water, the application of liquid roof coatings is easier and the spread rate is higher if the surface is smooth. In other words, you will need less of the material if you do the necessary work to create a clean and smooth surface.

Purchase Your Tools

The easiest way to spread the coating is to use a squeegee. If you are concerned about the material running down the side of a sloped roof, such as might be on an RV, you should take steps to prevent that from happening. Some products are specifically designed for slanted roofs. They are thicker and dry faster than those used on flat surfaces, but they also cost more.

From here, the application of liquid roof coatings is much like painting. A roller and a brush for hard to reach areas are the only tools you need.

Best Product To Extend Roof Life

Many Coatings are available in market but EPDM Coatings LLC. as having the good record in roof coatings suggest their customers to go for elastomeric coatings i.e. EPDM Coatings, Liquid Roof Coatings and Liquid Rubber because epdm has a track record of excellent performance since long. It has strong weather resistance and flexibility in terms of elongation and contract affected by severe changes in weather. It gives UV protection and lowers your bills due to the temperature control. Liquid EPDM is excellent for both new construction and roof replacement.

Liquid roof coatings are aftermarket products designed to extend roof life. Liquid Roof seals roof leaks, or merely provide a heat reflective or aesthetic roof coatings function over existing roof surfaces.

Liquid EPDM has been proven to outlast almost any other roofing substance. Acrylics, urethanes and other elastomers just don’t measure up. Nothing else provides the peace of mind and cost effectiveness of liquid EPDM.

Repair all types of roofs with EPDM roof coatings

The importance of roof coatings can definitely not be ignored. Consequently the awareness of different type roof coatings among the roofing contractors and the building residents is very necessary. Therefore get yourself well aware of what type of coating you need and the type of roof you have so that you are able to apply the roof coating which is best for your roof.
Most of the older mobile homes and RV’s around usually have metal roofs, most often aluminum. In order to keep this type of roof in good condition, again it is usually only required that you inspect it regularly and keep it clean. For most metal roofs, it’s okay to clean it twice a year using an automotive wash and wax cleaner.

EPDM rubber has a lengthy proven track record; it has been in use for more than 40 years in diverse conditions. Outfitting your roof with quality materials is an investment, which will pay off in the future because you will not have to spend as much money on roof repair or on replacing your roof sooner that you would wish to. Flexible and versatile, EPDM rubber is a material with much strength, which you can rely on to keep your family safe and dry.

Liquid Rubber for Coating Plywood

Liquid Rubber Coatings has been used directly over plywood to make a finished roof in situations where expediency and minimal cost were the primary considerations. Although this procedure results in a weaker roof structure, water-tightness can be achieved if the application is performed carefully. The joint between sheets should be positioned directly over a roof truss and securely fastened to prevent warping. Next, to seal the pores, coat plywood with oil based primer. Allow an overnight cure. Seal the joint by bridging it with a 6" wide polyester fabric strip. Apply a light coat of EPDM rubber over the joint, lay fabric into wet rubber and smooth out wrinkles. Complete job by applying a liberal coat of Liquid Rubber over entire roof surface, being especially careful to completely cover the fabric over the joint without skips or pinholes. Using an oil base primer on the wood considerably improves the appearance of a one-coat application of Liquid Rubber.

Liquid Rubber is excellent for Wood Surfaces Repair Product; Liquid Rubber can be applied to wood. We recommend first applying a primer coat using an oil base primer and then the Liquid Rubber after the primer has dried. Liquid Rubber can be colored using "universal" colorants available at any paint store. You can add up to one cup per gallon of paint thinner for easier handling when going over wood. Liquid Rubber is slippery when there is only a fine mist of water on its surface. Silicone and oil-based materials are considered unstable and should be avoided.

Elastomeric Roof Coatings proofs to be best water resistant coatings

EPDM Coatings http://www.epdmcoatings.com always gives solution for roof repairing project satisfying the needs of the customers with contingent services. When the time comes for first full maintenance of your punctured roofs, liquid rubber waterproofing can be easily refurbished usually by the application of an additional coat.

The primary advantages of epdm roof coatings are their economical, proven performance life, and ease of use. Roof coatings are generally one-component products that can be applied directly from the container. Today’s coatings are versatile and applicator friendly. Non-flammable products are also available.

An elastomeric coating is roofing applied in a viscous state. It has elastic properties, and can stretch in the summertime heat and then return to their original shape without damage. Elastomeric coatings usually contain polymeric materials, such as acrylic, and a white pigment, such as titanium dioxide, to make them opaque and reflective. An elastomeric coating is usually applied thicker than paint.

These rubber coatings are designed by the keen research from the top roofers to give maximum benefit of waterproofing. An elastomeric coating can be used on virtually any substrate including asphalt built-up roofing, concrete roofing, metal roofing, modified bitumen roofing, polyurethane foam roofing and single ply roofing.

Surface Coating Liquid Rubber

There are a number of applications for liquid rubber, ranging from injection molded toys to roof sealants. Hardware, craft, and home improvement stores carry or can order liquid rubber by request, and people who are interested in learning to work with liquid rubber can take classes which provide basic information for users.

Since EPDM Liquid Rubber Coatings cures by chemical reaction, a single heavy application will be preferable to multiple thin coats. A second coat will bond to a previous film but that bond will not be as strong as the internal bond within each layer. If a second coat is applied before the first has thoroughly cured, some wrinkling may result as the first coat absorbs solvent and swells. This will, however, recover as the solvent evaporates. It is generally recommended that only a single coat be applied over non-porous surfaces, the thickness of which can be varied as desired. Thicker films will take longer to cure through. Asphalt coatings and asphalt built-up roofs are considered unstable substrates and therefore, not recommended for coating directly with Liquid Rubber EPDM. EPDM COATINGS do carry a specific elastomeric which with a two coat application gives you a 10 year warranty.

Rubber Roofing Materials

The advantages of rubber roofing are many. Rubber roofs are durable, energy efficient and environmentally friendly (they are often made of recycled materials). Another advantage of rubber roofs particularly liquid rubber and liquid roof, one that often tilts the scale in their favor, is that they require low maintenance, unlike wooden materials for example. But some differences exist between the two types of rubber roofs, with each having its own advantages. When installing a rubber roof one should take into consideration the two options – a whole roof system or shingles. An entire roof covered with a large rolled rubber roofing piece is ideal for preventing any leakage whatsoever, as they have no seams in them. This may be a slightly more expensive option, but a wise decision for flat roof homeowners especially. Liquid Rubber roof shingles are authentic looking shingles that have all the advantages the rubber material provides, and are even lighter, making it easier to install. Regarding Rubber Roof Repairs The benefits of rubber roofing do not end there, as even if they do require repair some time after installing them, rubber roofs are easy to fix. Especially if rubber roof shingles are involved, but also in the case of a whole roof system, rubber may tear or even fall off. In such a case, the homeowner can easily repair the roof with spare pieces or special tape or liquid that dries into rubber-like material. Such liquid roof sealant can be applied to the entire roof upon installation to prevent any such damage in the long run.
