Butyl waterproof tape is an efficient and reliable waterproof material, which is widely used in various occasions that require waterproofing, such as roofs, basements, toilets, etc., and is a necessary product for timely filling of small leaks. But in order to give full play to the waterproof effect, butyl waterproof tape needs to be used correctly.
1. First of all, make sure that the surface is clean and dry. Moisture, oil or dust will affect the adhesion of butyl tape, and the butyl is firmly adhered to the substrate, which is the primary condition for the waterproof effect. Therefore, it should be thoroughly cleaned before use to ensure that it is dust-free and oil-free.
2. Secondly, choose the appropriate tape size and shape. Butyl tape can be cut into any shape according to the waterproof area according to the need, which has a miraculous effect when dealing with local waterproofing of complex areas, and the application is very flexible.
3. Butyl glue belongs to rubber, and the colloid curing at the temperature of supercooling will affect the paste effect, so it is recommended to use it in an environment above 7 degrees. High humidity can also affect the bonding ability, so it is necessary to use it according to the humidity standard marked in the instructions for use.
4. Butyl tape also has advantages and disadvantages, high-quality butyl tape has dense colloid, low initial viscosity, but with the passage of time, it will become more and more sticky, inferior butyl tape colloidal is sparse, and it looks good when sticky, but because the colloid is too thin, there will be a problem of falling off after a long time.
5. Finally, after the tape is pasted, it should stand for 24-48 hours to allow the colloid to be completely bonded to the base surface, and the closed water test can be carried out after 48 hours.
The butyl tape used in the exposed environment such as the roof should be checked regularly, and the damage to the butyl tape in the exposed environment is greater, so the damage should be checked regularly to facilitate timely repair.
At present, there are many types of butyl tape on the market, and aluminum foil butyl tape is the most common one, but the exposure ability of aluminum foil is poor, and this kind of butyl tape may fail after 2-3 years of use. You can try to use PVDF fluorocarbon film type butyl tape, the film surface has better aging resistance, and can be used for more than 5 years.
In conclusion, proper use of butyl waterproofing tape is the key to ensuring its waterproofing effectiveness. Following the steps above, and paying attention to the relevant matters and product quality, can effectively prevent moisture intrusion and protect your building structure.
