– Osel and Umbrella: because it does not present its expiration date or the conditions of its storage, despite the fact that it is not a requirement within the regulations of the attorney general’s office, it is useful information for the consumer.

– Sika: since at the end of the accelerated weathering test it presented softening and offered no guarantee.

– Fester: for not offering guarantee. The agency clarified that although it is not a requirement, it could give its buyer peace of mind.

– Umbrella and Fester: since they did not comply with the viscosity test and presented a range greater than that allowed by NMX-C-450-ONNCCE-2019.

– Arva, Comex, Osel and Thermotek: Well, at the end of the shelf stability study, lumps were found. For its part, Arva also proved to have a very low viscosity and Sika a very bad smell.

– Fester, Osel, Umbrella and Sika: did not meet the low temperature flexibility test.

– Comex, Imperquimia, Osel and Umbrella: these products presented softening and blisters.

– Arva, Fester, Imperquimia, Itum, Osel, Sika, Umbrella and Thermotek: did not pass the wet adhesion test.

Due to the fact that their stability on the shelf was qualified as excellent (they did not present creams, lumps, foreign matter, sediments, bad odor or microbial growth) they were: Aquarius, Fester, Itum, Pasa, Voller, Imperquimia, Volton, Xereton and Fester A.

Thanks to their excellent ratings during the wet adhesion test were the following: Aquarium, Comex, Fester, Pass, Voller, Volton and Xereton. While the best brands in accelerated weathering were: Acuario, Arva, Fester, Itum, Pasa, Thermotek, Voller, Volton and Xereton.

Likewise, he made known some general recommendations when making the purchase of one of these products:

– Buy in specialized stores: in this way you can count on the help of trained personnel and at the same time ensure the maximum useful life of the purchased product.

– Manufacturer Recommended Performance: Taking this into account, the information of the product will be counted with greater precision to waterproof the required area.

– Observe the product after uncovering it: because if when opening the product lumps, sediments, creams, oxidation products, dust or other foreign matter are appreciated, or if it gives off a bad smell, it will be necessary to return it because they are symptoms of a defective or expired waterproofing.

– recently manufactured products: all waterproofing must have the date of manufacture and expiration, therefore Profeco recommended that those that have been recently manufactured be chosen, so that in this way the product has a longer useful life than that presented in its container.

In addition, in the event that there is excess liquid, small patches can be made on the areas that may have been weaker, for example; downspouts or areas where water pools.
