Different Types of Caulk and Where to Apply Them

Caulking products can look pretty much the same once applied, but these products are in fact very different. There are a great variety of caulking product types and some are better suited for certain parts of a building than others. In this guide, we are going to take a quick look at the different types of commercial caulk and we share info on the best places to use these products.

Acrylic Latex Caulk

This type of caulk is often referred to as painter’s caulk and is usually the most affordable. The caulk is ideal for covering small holes and cracks in walls so you can apply a smooth layer of paint over the surface. Acrylic latex caulk can be used on a variety of materials like wood, drywall, and masonry but it won’t create a water-tight seal and it is only suitable for indoor use.

Vinyl Latex Caulk

This type of caulk is very similar to acrylic latex and is pretty easy to use and clean up. The product tends to be more durable compared to acrylic latex and once dried, it will create a harder substance that is also waterproof. You can use vinyl latex caulk indoors but it is more suitable for outdoor applications.

Acrylic Tile Sealant

This type of caulk is usually sold in tube form and is perfect for covering up holes and gaps between tiles or other areas that are prone to mould growth. The product is perfect for sealing openings and gaps and can be very durable but most don’t recommend it as a primary sealant.

Silicone Acrylic Sealant

Siliconized acrylic sealants feature a combination of acrylic and silicone. By combining these two products, the caulk becomes easier to apply and more durable. Silicone acrylic sealant can be difficult to clean up but it creates a water-tight seal and it is highly durable. This type of caulk can be used outdoors but outdoor use is not recommended.

Pure Silicone

Pure silicone is the most durable water-tight caulk type. It is mostly used in bathrooms and kitchens around sinks and toilets because the product clings to smooth surfaces and it can last decades. Pure silicone isn’t functional on porous surfaces like wood or masonry and is unsuitable for walls.

Adhesive Caulk

Adhesive caulk is a very strong glue that is ideal for holding two items together while sealing the gap between these objects. This type of caulk is also mould and mildew resistant which makes them perfect for areas like bathrooms where the humidity levels can be high. Adhesive caulk can be hard to clean up and will develop cracks or holes over time. When this happens, the product will need to be replaced.

Butyl Rubber

Butyl rubber is mostly used in roofing because it is highly durable, creates a waterproof coating and it is versatile. It is perfect for sealing roofs chimneys and gutters and can handle the effects of natural elements very well. Butyl rubber is easy to clean but it can be difficult and messy to apply.

Asphalt Caulk

This product is very similar to butyl rubber and has the same smell but asphalt isn’t as resistant to UV rays. It is usually used on the interior parts of rooftops like singles where it can create a waterproof seal without any exposure to direct sunlight

Fireproof Caulk

This type of caulk is bright red and is designed to keep fires from spreading in buildings. This product is mostly used for insulation, and to seal holes of electrical and plumbing lines in buildings. All of these caulk types can be very functional but only if you use them correctly. It is always best to use a professional like IB Caulking so you can get professional application and the right product for each task.
