Adhesion is necessary for a roof coating to protect your roof effectively. Without it, the roofing system won’t work as intended and could cause leaks or damage to the building below.
This post will discuss all the essential information you need to know about adhesion, including what it is, how it works, and what to look for in a quality roof coating.
What Is Adhesion in Elastomeric Roof Coatings?
Adhesion is defined as the force that holds two surfaces together. In terms of elastomeric roof coatings, adhesion allows the coating to adhere to the roof surface and create a waterproof barrier.
Elastomeric roof coatings are commonly used on flat roofs and metal roofs, as they provide superior protection against wind, rain, and sun damage. However, one of the most significant benefits of elastomeric coatings is that they are very versatile and can be used on various roofing materials.
Also, elastomeric coatings are highly durable and can last many years with proper maintenance. If you are considering an elastomeric roof coating for your home or business, be sure to consult with a professional to ensure that it is the right option for your roofing needs.
Factors for a Proper Adhesion
Compatible Elastomeric Coatings
While various elastomeric roof coatings are available, not every coating can be applied to every roof type. For example, there are coatings for Asphalt, BUR, Mod Bit, Capsheet roofs, Single-Ply Membranes – TPOs, EPDMs, Hypalons, and PVC -and SPF, Metal, and Concrete rooftops. In addition, each coating is formulated differently to offer the best possible adhesion on respective substrates.
How Compatability Works
For example, Single-Ply membranes are the hardest to adhere to because of how they physically break down and the residue that remains. Consequently, most roof coatings need a caustic primer or etching rinse before applying an elastomeric coating.
Although this costs money and time, it allows for proper adhesion. AcryShield A502 is a fast and uncomplicated solution for Single-Ply membranes offered by Tucson Rubberized Coatings. A502 enables specific and long-lasting adhesion to the Single-Ply membrane without requiring a primer or etching rinse.
Finding a roof coating that works with your specific roof membrane is essential to maintain your roof and cutting down on restoration costs.
Check the Surface of the Existing Roof Membrane
The rough surface texture allows the coating to grab onto and adhere to the substrate easily. The contact between the coating and substrate can be improved with a slightly rougher surface, as coatings are typically sprayed over the roof and then spread out to fill in any gaps or dips/pockets in the membrane. This gives the coating more of a chance to attach.
However, if it’s too rough, that can also create air pockets between finishing coats and roofing materials. Before beginning any application, you must pressure wash and clean the substrate to ensure there is no dirt, film, or other residues that could stop the coating from directly bonding to the substrate.
You also need 100% adherence to existing roofing material to ensure areas on your roof are not loose. If they are, take them off before applying a roof coating, as this can create pockets of air which creates defects in your roof coating system.
Finally, we will touch on cohesion or coating properties. This term refers to the various strength and binding properties that allow a cured coating to remain in one piece. Several things can affect cohesion, like weather conditions or the thickness of the coating itself.
That’s why it’s always important to follow your chosen manufacturer’s application guidelines—each has different standards for achieving optimal cohesion. Doing so will ensure you have solid elastomeric roof coating in place.
The Benefits of a Silicone Roof Coating
Silicone roof coatings have been gaining popularity recently to increase energy efficiency and reduce energy costs. Silicone coatings are a type of elastomeric coating, which means they can stretch and flex without cracking or peeling.
This makes them ideal for roofs constantly exposed to the elements. Silicone coatings reflect heat away from the building, keeping it cooler in the summer and reducing the energy needed to cool the building. In the winter, silicone coatings help to trap heat inside the building, reducing the energy needed to heat the building.
As a result, silicone coatings can help to reduce energy costs throughout the year. In addition to being energy-efficient, silicone coatings also have a long lifespan and require little maintenance, making them an ideal choice for commercial and residential buildings.
Silicone roof coating is a type of elastomeric roof coating that can help improve the impact resistance of your roof. This can be especially important during winter when ice and snow can damage roofs.
Silicone coatings can also help to improve the energy efficiency of your home by reflecting heat away from the surface of your roof. In addition, silicone coatings are less likely to crack or peel than other elastomeric coatings, making them a good choice for long-term protection of your roof.
Prevents Ponding Water
Silicone roof coatings are a great way to prevent ponding water on your roof. Ponding water is standing water collected on your roof, which can cause weathering and other damage to your roof.
A silicone coating is a liquid you can apply to your roof, creating a barrier preventing ponding water from damaging your roof. Silicone coatings are also UV resistant, so they will help to protect your roof from the sun’s rays. In addition, silicone coatings can also help to protect your roof from hail and wind damage.
Applying a silicone coating to your roof is a great way to prevent ponding water and keep your roof in good condition. A silicone coating is the best option if you want to prevent ponding water on your roof.
