What Type Of Caulk To Use – And Why
There are many different types of caulk that are available. Some are listed by use, while others are listed by type. All of them have crazy guarantees that tout 45 or even 60 years! No caulk will last you 60 year or even 45 years. However if Company B makes a lesser product and says it lasts 40 years then Company A has to put down 50 years or nobody will buy it.
Plasticizer is what makes the caulk stretch and keep from cracking. Some products use better plasticizers and better methods of joining it with the caulk. Please take our knowledge from years of experience as an Indianapolis painter or contact us if you need a professional painter.
The Types Of Caulk
- %100 Silicone Caulk – This is not to be confused with a Modified Silicone. %100 silicone is clear, NOT paintable. However it will not crack and fall apart like acrylic caulks, shrink when dry or get easily destroyed by mildew and extreme weather.
- Modified Silicone – Modified silicones are a newer set of caulks that are decent at just about everything but excellent at absolutely nothing. An absolute great option when you are looking for better bonding with the properties of regular silicone. Lower quality modified silicone caulks will tend to break down and become greasy messes, especially in heat.
- Siliconized (Modified) Acrylic – Siliconized acrylic caulks are great for bathrooms or other surfaces where the caulk will NOT be painted. i.e. around the bathroom or kitchen counter. They can be painted but there are better options if you will be painting over the caulk.
- Adhesive Caulk – Adhesive caulk is great for some applications where you need the surfaces to be joined together and not just sealed. This is where you may use an adhesive caulk. However you must realize that while these products are made to look like caulk and function like glue, they generally do not hold up to harsh environments.
- Acrylic Urethane – Acrylic Urethane caulks are the best caulks for most situations. The caulk takes a long time to dry, but that is about the only downfall. Bonding, flexibility and long lasting are far superior to anything else due to the urethane.
- Fast Dry Caulk – You can find several fast dry caulks. Sometimes they are called “high solids”. These caulks are made of several different materials and usually are not the best solution. However, in a pinch these caulks are great for the larger cracks that most caulks will not fill or when you have a missed spot that you need to hit right before painting. Often these caulks can be classified as another resin system but we put them in their own group because of their specific use.
