Know why Caulking Bathtubs and Sinks is an Outdated Procedure


Bathtubs and sinks are commonly attached to the walls with caulk. This adhesive is made from silicon, latex or even acrylic. But, whatever the make, caulking is temporary. Within a few months, you notice cracks in the caulk or find it peeling. To fix this issue, you again resort to re-caulking. But, you just get into a continuous loop repeating the procedure every few months. We, at pFOkUS earnestly believe that caulking bathtubs, sinks or shower corners is absolutely outdated. We have a revolutionary product that seals all these surfaces with permanent results.

Why is Caulking Outdated?

  • We call caulking outdated because it lacks modern science, technology, and the freedom of maintaining your surfaces once and forever. 
  • Caulking or re-caulking is a traditional practice of sealing shower corners using acrylic or silicone caulk.
  • Caulk shrinks and cracks in dry settings and peels off in wet settings. Re-caulking is nothing but a band-aid solution to the existing one, leading to similar damage issues again.
  • Caulk is also very bulky. With today’s new age products, it is possible to seal caulk with powerful epoxy resin sealers, which give a natural and sleek appearance, unlike caulk.
  • Caulking bathtubs, sinks or showers should be done with powerful products, which are not affected by different weather conditions, as shower areas will always be damp.
  • As caulk is available in very few color choices, it makes it very restrictive to match your interiors. If you use an unmatching colored caulk for your surfaces, it will pop out aloud and ruin the beauty of your interiors. With advanced methods and technology, today, you get new-age epoxy resin sealers that can be matched with the colors of your interiors.

Which is a Better Solution?

These facts on caulking, brought to the surface, the significance of new age sealers, which totally abolished the practice of re-caulking. If your contractor advises you to go for re-caulking for your caulking repair issues, then it is time you switch to a better solution. pFOkUS has created Sentura – a powerful two-part flexible solvent-based epoxy resin adhesive built on a 1200psi adhesion. Sentura beautifies and seals your surfaces with its narrow and sleek appearance that not only looks natural, but also is permanent. Sentura is an exquisitely designed sealer that can be pigmented in more than 40 shades to match your tile color. Our epoxy resin makes the surface waterproof and does not let any weather settings damage the tile and grout. 

So, forget recaulk and use a better caulk substitute – Sentura from pFOkUS. Here is how you should use Sentura to seal your shower corners, sinks and bathtubs.

How is Sentura better than Caulk?

  • Sentura does not crack in dry weather conditions
  • Sentura never peels off like a caulk when the temperature conditions are humid or wet.
  • By caulking bathtubs, you know at the back of your mind, that you will have to get it done again, but with Sentura, you know that it is forever.
  • Sentura does not have a bulky appearance like caulk.
  • Sentura can be pigmented in more than 40 shades, enabling you to match it with your tile corner. Caulk gives a whitish and bulky appearance on your corners, ruining its overall look. 

What is the Right Way of Sealing Showers, Sinks and Bathtubs with a Caulk Substitute?

 For sealing instead of caulking bathtubs, sinks or showers, a proper procedure has to be followed:

  • The existing caulk should be first removed.
  • The entire area should then be cleaned with shower approved cleaners. We recommend you to use our powerful Imperia Deep Clean. It is a deep-penetrative cleaner that seeps into the pores and eliminates all the hidden germs, stains and mold from the corners, giving you a thoroughly sanitized surface. 
  • After cleaning, wipe the area dry and wait for a few hours before you begin sealing.
  • Once the corners are dry, Sentura adhesive should be used to fill in the corners. We have explained in detail how to use the Sentura kit below.
  • Once the epoxy resin filler – Sentura has properly covered all the grout lines, it is best to seal the grout lines with an epoxy resin grout sealer – Caponi to prevent any further damage.

 Here is How to Use Sentura:

Please follow the instructions given below to use the Sentura kit.


  • Sentura Part A
  • Sentura Part B
  • Empty Container
  • Spatula for mixing


  • Remove all part A contents and remove all part B content in the empty container.
  • Mix thoroughly in the empty container using a spatula.
  • Put mixed material into the applicator bag.
  • Apply a smooth line of Sentura at the corner of the shower tile where the floor tile meets the wall tile. For bathtub sealing, apply a smooth line of Sentura at the surface where the edges of the bathtub meet the wall and the floor. For sink sealing, apply a smooth line of Sentura at the junction where the sink meets the wall. 
  • Use water to smooth Sentura.
  • Use Sentura to also fix any cracks or crevices.
  • Let Sentura dry completely. 
  • Once dried, use Alco – our paint thinner to remove the extra build-up that may have formed while using Sentura. Alco helps to give a thoroughly neat and clean surface.
