How to Create a Moisture Barrier with Waterproof Tape

They’re a low-cost, simple to apply and long-lasting option for sealants, coatings, and caulking. Their simplicity does not protect them from damage caused by incorrect use.

The primary factor that increases the strength of bonds between waterproofing tapes and surfaces is surface preparation. This will help avoid failures like peeling or delamination.


The waterproof tapes form a barrier that blocks the infiltration of water into building products. This can help to defend against rot, mold and corrosion. Waterproof tapes are often used in conjunction with other waterproofing materials to ensure long-lasting durability.

If you are applying a waterproof tape it is important to follow the steps to ensure a sturdy bond. Smoothly applying the tape and evenly is vital. Wrinkles, creases, and bubbles could result in gaps that allow water to enter. The result is damage to the surface and result in further damage.

The temperature of the application should be considered when making tapes. Temperatures that are high can cause the adhesive to soften and less pliable, which can affect the strength of the adhesive. This can also lead to the loss of adhesion to the substrate. Temperatures that are too low, on the contrary, could result in an inadequate wetting of the substrate by the adhesive. This can result in a weaker bond.


Waterproofing tapes are a great alternative to caulking, sealants and mastics, for numerous motives. These tapes are quick to use, cost-effective and provide a strong protection against water. This helps to protect surfaces from corrosion.

If you want to make a better impression for a better result, cut the waterproof tape at the length desired and leave a couple of overlaps on one end. Peel off from the backing and expose the tape’s sticky surface. Apply pressure to the surface by smoothing any imperfections or wrinkles to guarantee full contact with the substrate and the formation of an airtight sealing.

You can use a platen or handheld roller to apply tape on surfaces that appear dirt or rough. The pressure of a couple of psi is sufficient to achieve satisfactory surface contact. Avoid applying too much force because it could reduce the strength of adhesive. Tapes that are waterproof can be applied in a myriad different outdoor and indoor tasks, including patching leaks, insulation or wrapping pipe lagging, sealing curving windows, glazing bars, as well as protecting metal above ground from rust.

Surface preparation

Check that the surfaces that will being taped remain dry, free of foreign material. Prior to applying the tape, it is recommended that you apply a thin layer of adhesive enhancer on the substrates.

Surface preparation is a crucial process to ensure the strength of the adhesive bond and many failures are caused by contamination or dirty surfaces. The use of solvents such as an isopropyl alcohol solution (70% IPA, 30 percent water) for the removal of dirt, dust as well as fingerprints and smudges will substantially increase the adhesive power for the adhesive. An acetone cleaner or degreaser may be needed to remove heavy oils on the surface.

The porous and fibrous material such as concrete, wood and particleboard should be sealed in order to create a uniform surface for the adhesive bond. This is accomplished by sanding or roughing the surface with a wirebrush or sandpaper. This can also improve the strength of the adhesive.

What is the best way to use

They are simple to use and require less tools than sealants, caulking and mastics, or coating products. They are also more affordable and easier to put in. Their simple nature, however, is not enough to shield them from the failures caused due to poor installation methods.

To avoid these issues Be sure to clean the surfaces prior applying any type of tape. Lint, dirt, the paint keo va ong nuoc or plaster, as well as other products increase the likelihood of extra adhesion build-up and the eventual failure of tape. Be sure to wash areas that are two to four inches beyond the surface to be repaired.

A bit of oil can help remove a layer of tape debris. Use a cleaning or cooking oil to soak a sponge and then buff off any tape residue. Oil dries out adhesive layers making them easier to remove. Rubber alcohol can be used even if you don’t have oil. This can be used on glass and metal surfaces since it does not stain them and it evaporates quickly.
