Question: I are looking at a credit application where I need to protect holes in precast concrete floor structures from filling with water. Will self adhesive videos stick to a very smooth concrete finish off?
Answer: If an individual were to attempt to employ a self backing film on solid such as the Glass Plastic self adhesive product, no matter of how smooth the completed, you would certainly swear completely not any adhesive. Yet in case you took the same roll and tried it on glass, it would stick beautifully. Part involving what we take advantage of with glass safety is the ionic nature of a glass.
For your project, the much more intense adhesive would become needed. This will depend on on how smooth the concrete getting covered is, plus whether or certainly not it is sealed. Many of us have had really a few customers use one regarding our products to cover concrete whilst they are re-surfacing asphalt parking tons. This is honestly about the sole experience we include with covering concrete, because we generally recommend against that. The product that has been used is a new 6 mil motion picture with the adhesive program called 479. Biscuit Production Line is fairly intense as surface defense films go, yet this is normally needed to adhere to concrete, and even then the particular concrete needs to be pretty clean or it can not adhere properly enough to support its weight.
It is important to be able to recognize how long the film would end up being in place. Surface protection films should be applied to cured surfaces in temperature ranges fairly close in order to room temperature intended for the adhesive techniques to “wet out” properly. In cooler climates, quite the few of our own buyers warm the progresses, and say that they work well about colder surfaces.
Microscopically speaking, concrete has a very open up porous system, plus it often holds a large amount of moisture. Moisture will be the enemy of mucilaginous systems of typically the types used about surface protection motion pictures. A water-based cement adhesive system is smooth until the water is removed, after that it becomes gross. If water is present it may re-hydrate the backing system to some degree, and trigger not only the loss of adhesion, but can in addition cause adhesive residue transfer. If the surface protection film is left about concrete to have an expanded period of time, adhesive residue shift becomes more plus more likely. The sole applications where we now have had reports from it being used successfully are for times, not weeks or perhaps months.
In the event the concrete is sealed, then the film follows much easier, and the probability of troubles are reduced substantially. Once the film is well adhered to sealed tangible, it will normally stay adhered, actually during inclement climate.
