Posted by

Are you fed up with recurring caulking issues? Are you again browsing the internet searching for a better-quality caulk? If yes, then this blog will be an eye-opener to you about a better caulk-substitute that gives you permanent results. So, do not worry if you don’t know how to caulk. We will direct you towards easier caulking solutions provided by experts.

Why Some Expert Companies do not Use Caulk:

Caulk is used to seal shower corners, sinks and countertops. But both silicone and acrylic caulk provide very temporary results. Caulk tends to get damaged after a few months, requiring you to invest in re-caulking every few months. Caulk starts peeling in wet conditions and tends to crack in dry weather. Within a few months, it deteriorates and gives birth to mold on its surface as well. 

Low contractors or ignorant companies will not advise you about the better and permanent solutions for sealing shower corners or sinks, as they are looking for regular business. They keep caulking and re-caulking at your request, making good money every time. But, only an expert company would guide you towards permanent and better solutions. 

In this article, we shall go through the right way of sealing shower corners, sinks and countertops with the right products and tools and put an end to your search for how to caulk.

How to Remove Damaged Caulk in the Right Way?

Before you proceed with a caulk-substitute to seal your corners, you need to first remove the old and damaged caulk the right way. If you do not remove it properly, it will further ruin the appearance of your tile. 

How to Remove Caulk:

You will need a few essential tools to get rid of your removable caulk and damaged grout from the corners. After you remove the old caulk, can you apply a caulk-substitute for permanent sealing.

Arsenal Required:

  • Triangle grout removal tool (just in case your grout is too rigid)
  • Razor scraper with 5 extra blades
  • Utility Knife

How to Remove Damaged Caulk


  • Using a razor scraper, you need to glide it along the grout or caulk line from one end to the other. This way, you will cut the edges of the caulk.
  • Next, use the scraper in the corners as well to cut the caulk’s hold from the sink, countertops or tile. This will ensure that the caulk is no more bonded to the surface.
  • After that, you need to use the triangle grout removal tool to get rid of the stubborn dirty caulk left behind after using the scraper. This tool is used by expert companies as it does not damage the surface and easily removes the grout in the joints.
  • In the end, again use the razor scraper to remove any leftover pieces of black caulk left behind in the grout joints.
  • Lastly, remove all the caulk remnants on the tile and ensure that the surface is clear from old caulk.
  • Clean up the debris and ensure that the surface is clean.
  • Next, you need to use a good-quality tile and grout cleaner to clean the area before you apply the caulk-substitute. You can use Imperia Deep Clean from pFOkUS, it is a strong and robust deep-soaking cleaner that will give you a prepped and sanitized surface.

  • You can also use Alco-paint thinner from pFOkUS to remove any oil or soil residue from the surface.

After you have followed the above instructions properly, you will find a clean and clear area, where you can use the caulk-substitute for permanent sealing. This procedure will get rid of your dirty, black or gray caulk forever. 

How to Use a Caulk-Substitute:

Before we explain how to use a caulk-substitute, you need to first buy the right product. You can try using Sentura from pFOkUS. It is a two-part pigmented flexible solvent based epoxy/resin, based on 1200psi adhesion. You can even caulk Sentura as the best caulk remover, as it has totally abolished the practice of caulking and given you a permanent solution. This product will make your corners in showers, corners of sinks or countertops, leakage resistant. 

The basic idea behind caulking is to seal these corners and make them inaccessible to stagnant water and subsequent bacteria and mold growth. When you use a high-quality caulk-substitute or shower corner sealing product, you seal your corners permanently and will never have to worry about leakage, bacteria, water clogging or mold growth again.

What Qualities should a Good Caulk-Substitute Have?

A good caulk-substitute should never peel off in wet conditions or crack in dry weather. It should not be damaged with harsh chemicals. Use a product that can be pigmented in more than 40 colors so that you can have the desired color in your shower tile. A good product should not appear bulky and should look sleek and natural. 

Arsenal Required:

  • Caulk-Substitute ( you can use Sentura)
  • Paint-thinner ( you can use Alco)


Good Caulk-Substitute

Here is how you can use a caulk-substitute:

  • After you have removed all the existing residue or old and damaged grout, and also cleaned your surface, you can wait for it to dry completely.
  • Next, use a high-quality shower corner sealant.
  • Follow the instructions written at the back of the product to use it properly.
  • To clean any build-up, you can use a paint thinner later to deliver a neat and fresh looking surface.

This way, you can use a good caulk-substitute to seal your shower corners, bathroom tile, sinks and countertops.

  1. I’ve been so pleased with the fact that somehow I landed on this page because I have been having trouble with caulking. Indeed, caulking has proven to be such a significant headache in more recent times, and hence alternatives are what I need.
