How to Dull Shiny Silicone Caulk – Process Discussed

How to Dull Shiny Silicone Caulk

If you have already applied silicone caulk and the surface looks unexpectedly shiny, then you can follow the below process. For your convenience, we are going for a step-by-step process.

Required Materials

  • Cloth
  • Rubbing Alcohol

Step – 1: Let the Caulk Dry

This is the very first step and you have to make sure it is done. Let the surface dry properly where you have applied your shiny silicone caulk. You cannot go to the next step until you let the caulk dry.

When the surface completely dries, it reflects the ultimate shine on the surface. Then you can decide easily how much you want to make the surface dull.

Step – 2: Use Rubbing Alcohol

Now take a cloth and tip some rubbing alcohol on it. Make sure the cloth is new and clean. Then run the cloth along the edges of the surface first where you have applied the silicone caulk. If you realize the glossiness is losing, then you can continue the process to the entire surface.

Rubbing alcohol on a cloth works like sandpaper. Hence, while running the cloth over the surface it makes the surface rough. Gradually, it de-glosses the sheen.

Step – 3: Repeat the Previous Step

If necessary, you may have to repeat the previous step. The more you rub the surface, the more it will become matte but gradually. So, you have to be careful with the process. Do not be overwhelmed by the process.

Otherwise, you will find no purpose in using silicone caulk in the end. However, also make sure you do not take too much rubbing alcohol. Taking only a little amount should do the work.

Step – 4: Let the Alcohol Evaporate Naturally

When you are done with the previous steps and get your desired finish, leave the surface. Let the alcohol evaporate from the surface properly. Professionals do not suggest wiping the surface with water after being done with the job.

Or, do not force the drying process of the surface by taking some unnatural steps. Rather let the alcohol evaporate naturally without creating any interruption. So, the alcohol will eventually dissipate. This way you can make the surface of silicone caulk a bit less shiny.

If you think after buying silicone caulk, it is a loss project to buy matting powder, then you can simply use powdered sugar. Powdered sugar is easily available in the kitchen. You just need a little amount from it.

Also, using this material is easy. Just sprinkle some of the powder over the surface where shiny silicone caulk is applied. Make sure you sprinkle the powder when the caulk is still wet. Then when the caulk becomes dry, wipe off the sugar. The final result will be hopefully satisfactory.

  • Other Household Powders

You can also use other kinds of powders that are available in your kitchen like cornstarch or baking powder. Moreover, you can use talcum powder as well for this purpose. Again, using such kind of powders delivers a matte finish against a shiny caulk.

However, using powdered sugar has been found more effective. Other types of powders do not always deliver the expected result. Moreover, their result varies depending on several factors.

Again, some users have complained that the powders do not clean off properly while wiping. Moreover, they leave marks sometimes on the silicone caulk.
