Border tape for a bath: types, installation instructions

Bath border tape is a useful and necessary piece of equipment for any bathroom. It acts as a sealant to keep water from leaking into crevices and damaging the wall between the bath and the wall. It is worthwhile to include this straightforward but efficient tool in your home improvement projects because it keeps your bathroom clean and intact.

The market is filled with different kinds of border tapes, each made to suit a particular set of requirements and tastes. While some tapes can be installed easily without the need for additional adhesive, others may need it for a more secure fit. The material that is used, such as silicone or PVC, also has a significant impact on how long-lasting and mold- and mildew-resistant the tape is.

Border tape installation is a simple task that requires a few simple tools and close attention to detail to be accomplished. A good seal and good adhesion of the tape are guaranteed by proper installation. We will walk you through every step of installing border tape in the sections that follow, from readying the surface to making sure the fit is neat and tight.

Description and advantages of the material

Every day, a new product hits the construction market that makes it possible for you to perform repairs quickly and effectively. The plumbing booth acts as a dependable hermetic material to keep water out of the crevices. The only minor annoyance is that the tape only lasts for three years on average before the strip needs to be changed. Products need to be applied with adhesive compositions even though they are self-adhesive. The benefits of using border tape in the bathroom:

  • Simplicity, convenience, installation speed.
  • Good decorative characteristics.
  • Universality – bath, sink.
  • High humidity resistance.
  • Flexible polymer structure of the material.

Elastic products, allowing them to be mounted on a variety of shaped joints. The effects of temperature drops and household chemicals like detergent and cleaning agents do not weaken borders. The plumbing equipment zone gains a finished and aesthetically pleasing appearance when the strip is adhered to create a consistent and tidy joint line. You are able to apply border tape to the bathtub on your own. It’s not necessary to be an expert repair technician for this. The material is affordable and very well-liked.

Be advised that polymer borders may react acidically with certain substances. As a result, the border will not last as long as the manufacturer has stated and the polymer strip’s appearance may deteriorate.

Types of materials

It is nearly impossible to install plumbing so precisely that gaps do not form when doing bathroom repairs. Plumbing equipment cannot function without the hermination of joints. By doing this, mold, moisture, and fungus are prevented from growing on the walls and flooring. In the past, joints were sealed and moisture was insulated using cement mortar. You can now easily attach self-adhesive material and put the issue out of your mind for a few years. A flexible strip seals straight or curved joints reliably, dries fast, and is simple to install. Bath borners vary in size, ornamental style, and fastening technique.

By profile

There are two varieties of self-adhesive bath border tape: corner and figure-shaped. The corner products located in the center feature a fold that creates a consistent edge next to the wall and the bath’s side. Perfect for filling in narrow spaces, this adhesive is simple to attach to plumbing fixtures made of acrylic, metal, or fiber cement.

Two currency lines that split the length of the strip into three segments distinguish figure borders from corner products. Since the central section is required to subtly conceal a large space between the wall and the side, glue is not applied to this area. The figure tape is processed with glue in two additional parts. You must consider the size of the clearance required to seal the border in order to select the appropriate product.

According to the parameters

Bath borners come in different sizes. The bands range in length from 3.2 to 3.5 meters, depending on the plumbing’s dimensions. There are four primary groups based on the width of the products:

  1. 10×10 mm border for narrow joint gaps.
  2. Tape 20×20 mm wide for medium cracks.
  3. Strip 30×30 mm wide – large holes.
  4. Figure products have a size of 38 mm in width.

The large joints between the plumbing’s sides and walls can be securely sealed using the non-standard borders (60 mm). Measure the length and width of the bath before purchasing a border strip. Should the parameter surpass 320 cm, two self-adhesive pieces must be purchased.

By decorative execution

Since white borders are so versatile, they go well with snow-white plumbing and tile cladding in any shade. The majority of manufacturers produce them. It is less common to select ribbons in shades of light pink, pale green, or cream-beige. Manufacturers sometimes emboss or figure-prune the edge of their borders. These materials complement the room’s design and accentuate the interior in a positive way.

By the method of installation

One key and practical feature of a self-adhesive bath border tape is that the adhesive is applied to the back of the material. The glue layer is sealed with a protective film to ensure that the adhesive material maintains its properties. It is taken out and the plumbing is sealed with border tape.

Installation of a non-mechanical strip is done on silicone or acrylic sealant. The material securely fastens the strip and prevents water from passing between the plumbing’s edges and the wall. It is important to consider whether the tape is self-adhesive before making a purchase.

Bath border tape seals the edges where the bathtub meets the wall, preventing water damage and the growth of mold. It’s a cheap and practical solution. This article examines the various kinds of border tape that are available, discussing their features and advantages. It also offers simple installation guidelines that guarantee a tight, waterproof closure. Whether you’re a do-it-yourself enthusiast or a homeowner in need of a fast fix, knowing which tape to use and how to apply it correctly will help you keep your bathroom spotless and long-lasting.

Rules for the choice

Synthetic materials that provide the goods with the necessary elasticity, flexibility, and water resistance serve as the foundation for borders. Fudalon adhesive sticks well to a variety of surfaces and is "not afraid" of temperature and humidity variations. Considerations for selecting a self-adhesive border tape for the restroom include the following:

  • Profile shape – angular or curly type.
  • The presence of intermediate corners, applicator.
  • The inclusion of mold protection in the tape.
  • The width of the product must correspond to the joint.
  • Color scheme if it is important when buying.

The lifespan of the produced borders is set, typically at three years. Reviews from customers claim that a tape-male can last five years if handled carefully. You can always switch out the material if the product starts to look ugly. Using self-adhesive products is more convenient.

Installation process

Even though installing border tape for a bathtub doesn’t take long, proper installation is necessary to ensure high-quality joint sealing. The tasks involve strip cutting, adhering, and surface preparation. Before installing plumbing, masters advise filling the space between the bathtub and the wall with a specific silicon.

Preparatory work

You must clean and dry the surface in order to get the ideal fit of the strip on the wall and bathtub. The caliber of sealing determines the joints’ resistance to water:

  1. The sides of the bath and tiles are cleaned of pollution, if they are.
  2. Perform degreasing – alcohol cleaning without abrasives.
  3. Dried or thoroughly wipe the surface with a cloth.
  4. When re -gluing, the old border tape is removed.

As stated on the packaging, silicone (sealant) needs time to solidify before being adhered to the strip. To avoid scratching the tiles and bathtub, any extra neutral silicone is carefully cleaned.

Installation technology

It is best to have the bathroom temperature at least +10 degrees Celsius when installing a flexible border, but ideally +20 degrees. You must measure, mark, and cut the strip with the allowance before installing. You cannot use a hairdryer to briefly warm up the curb in order to increase the material’s elasticity. The following guidelines must be followed in order to apply border tape to the bathtub correctly:

  • Before applying the tape, the surface of the bath is prepared.
  • The installation of the strip begins along the long side of the bath from the corner.
  • The protective film needs to be separated gradually at 10-15 cm.
  • The material is neatly smoothed, you can’t stretch the tape.
  • It is necessary to monitor the density of the adjacent border.

The excess curb is cut off and an overlap is placed in the strip’s corners. It is not advised to use the restroom right away after installation to allow the glue to fully dry. After a day, you should swing the border slightly in different directions to assess the joint’s strength and tightness. If the tape is not strong enough in some areas, apply construction glue using a brush, press the material firmly, and let it dry completely.

Installation instructions

The border is complete because the tape includes settling corners. Mark the surface and gather the necessary tools and materials before gluing the strip. Following the purchase, you should confirm that the border’s width and length are sufficient to seal the joint all the way around.

Preparation of tools

You’ll need the following equipment and supplies to glue the curb:

  1. Decorative corners.
  2. A mounting knife with a sharp edge.
  3. Roulette and pencil (not a marker!).
  4. Maslar tape, brush, glue.
  5. Sealant for plumbing, alcohol.

Use neutral sealants to fill the joints since the tape is not resistant to the effects of acids.

Marking and cutting stripes

It takes preliminary marking in order to cut the border correctly. It is best to use a pencil rather than a marker, as the latter may leave marks on the tape. Mark the product’s figure edge on the tile with a pencil. When cutting a self-adhesive bath, leave a 2-3 centimeter margin. The completed border piece is bent in half and heated with a hair dryer so that the heated glue adheres better to the bath’s sides and tile surface. Should the tape have curls, the kit’s corners will approach it.


You can begin installing the joint product after cleaning the surface and cutting the curb. Method for applying border tape in the restroom:

  1. Mark the border of the border on the wall/tile.
  2. Play the gap along the length.
  3. Glue decorative corners if they are.
  4. Bend the curb and warm the adhesive layer with a hairdryer.
  5. Tear off the protective film of the tape 15-20 cm.
  6. Attach the curb to the junction, press tightly.

The seam sealing will be more dependable the more firmly the tape is fixed. The joints are meticulously smoothed with a wet spatula and "sealed" with a sealant prior to the curb installation. Check the stability of the fixation after a day, and if required, use liquid nails or building glue to attach the tape.
