Clear Sealant

Which clear sealant?

There are many different clear sealants available on the market. Most of these products that say clear on the packaging are not that clear when applied. Some clear silicone sealants are cloudy instead. Adiseal Ultra Clear is the best waterproof clear sealant for many different reasons. It is crystal clear when first applied and dries crystal clear.

Clear silicone sealant

Some of the cheaper clear silicone sealants tend to be almost white in colour instead of being clear. Adiseal Ultra Clear is crystal clear when applied and stays crystal clear when it has dried. The image below on the left shows silicone clear vs the old formula of Adiseal Ultra Clear on the right. The new version of the Adiseal Ultra Clear is even more clear than before.

Clear sealant in water

One of the reasons why Adiseal Ultra Clear is the best clear sealant is because of how it remains clear even when submerged in water. In our test, it was the only product to remain clear in and above water. To carry out the test, we first applied the products from different manufacturers inside new clean plastic cups. The cups were then filled halfway with water. They were then covered by a plastic sheet and all cups were kept together in the same conditions. The image below shows the result of the test after the products were left in water for a few days.

As can be seen from the image, the competitor products being tested turned white where they were in contact with the water. A competitor product claiming to be the number 1 sealant actually performed the worst. It was the only product to turn white both above and below the water line. In fact this competitors old formula performed better than their new formula. Their old formula only turned white below the water line whereas their new formula has turned white below and above the water line.

Adiseal performed the best in the water test. It remained crystal clear above the water and only turned slightly cloudy below the water.

Frequently asked questions about clear sealant

How to remove clear sealant?

To remove clear sealant, varies on what type of product it is. Most silicone sealants are solvent based. For solvent based products, Adisolve can be used to deactivate the product. Spraying Adisolve on top of the product will help the silicone peel away from the material it is stuck to. Use a sharp item then to cut away any sealant that remains stuck to the surface.

How to apply clear sealant?

To apply clear sealant requires a clean surface first. If there is any existing sealant, this will require removing before applying the new sealant. Adisolve will help remove old sealant that is solvent based. Old sealant can also be removed using a sharp item like a knife.
Once the surface is clean, apply the sealant on top. Pushing the sealant into the gap will provide a better seal. Smooth the sealant then allow the product to dry. Some people apply tape on the sides to get a good clean finish on the sealant.
