Purchasing Guide for the Best Roof Sealant Products
Below we have mentioned some essential aspects of a typical RV sealant:
1. Purpose for application
First, consider why you actually need to seal the roofing of your RV. It might be the fact that you are only facing a leakage. In this case, you will only have the requirement of a tube sealant in order to manage this issue.
Nevertheless, in the case the roof is not properly taken care of for an extended period of time, or likewise, there was a degradation all by itself and the whole thing needs to be recoated once again, you will require a reparation in the roof. The roof must be repaired in these cases. These activities should take place before you decide to apply any sealant offered in the industry.
A study of the extent of deterioration is likewise essential since it will help to figure out the amount of work that you will be required to undertake. For instance, you might only be required to purchase a sealant tape in case you only have a minor defect in the rooftop of your RV.
2. Roofing material
The substrate wherein the RV roof sealant will be applied, is decisive to determine what type of RV sealant you require to purchase.
You will come across 3 primary categories of materials utilized in rooftops at present which is as follows:
a. Rubber – Majority of recreational vehicles have rubber rooftops, and this is because of its affordability, as well as reduced weight. On the other side, the rooftops that are manufactured with this material, may not be structurally suitable in most cases so as to support any heavy impact or weight.
Regarding rubber, we will also encounter currently two variations of synthetic products which are TPO and EPDM.
EPDM (Ethylene Propylene Diene Monomer). Being extremely rubbery in nature, there is no need for an additional UV protectant; however, it is imperative the fulfillment of a recoating on a regular basis. In the course of time, these types of RV roofs are going to appear rather chalky because of oxidation.
TPO – It is the other synthetic product derived from rubber. It is Thermal-Poly-Olefin. This material has a higher level of rigidity as compared to EPDM, and is much glossier as well.
Fiberglass – At present, you will not come across many RV rooftops which are made from fiberglass, but they still exist. Roofs made from fiberglass will be able to oxidize effectively just like the EDPM roofs out there. They shine more in visual appearance.
Aluminum – These are coated using a clear coat, they become reasonably stable and also do not require much maintenance. In aluminum rooftops, a tube sealant may suffice. But with aluminum, I have not worked myself with sealants.
3. Tear resistance and elasticity
Elasticity is the ability of any typical sealant to turn or twist without sacrificing its sealing properties whatsoever. Nevertheless, the term “tear resistance” implies to the raw strength of the material and also how much force it is able to endure prior to breaking up. This applies to both liquid tapes as well as sealants.
When it comes to tapes, you will require a material that is quite fixable and also not easy to tear while the liquid sealants are going to need some sort of flexibility for adjusting to the changes. It is important to keep this in your mind while making any choice since you will need to utilize the appropriate materials in the proper areas.
A sealant that is extremely rubbery in nature will be appropriate for those joints which are susceptible to expansion and contraction, while a rigid or more powerful sealant will be appropriate for those areas that need to support some weight.
4. UV resistance
Ultra Violet or UV rays are actually non-visible radiations that are derived from the sun causing chemical reactions in quite a few substances. It is going to make your RV rooftop wear out in the course of time. For this, you have a couple of solutions that can provide the most desirable results.
The first one would be to get hold of a roof sealant which is UV resistant and will thus help to increase its lifespan.
The second fix will be to get hold of a cover for the RV which will help to safeguard it from any inclement weather when not in use.
5. Simplicity of application
You do not want to purchase a roof sealant, only to realize afterward that you will require something else which is not available to you, for example, an activator or a primer.
Therefore, it will be a prudent decision to check properly at first. You will likewise need a sealant which is simple to apply as well as clean up whenever required.
