Flexible filler also known as decorators caulk comes in external and internal grades. Caulk, by definition, means to make water or air-tight by filling or sealing, so decorators caulk is ideal for sealing any gap such as around windows and doors, between skirting and walls and the similar. In short the answer is no, caulk is not quite the same as silicone sealant. The main difference between the two is their flexibility or elasticity as silicone sealants tend to be more flexible than caulk-based fillers.

As with applying the caulk, move your finger slowly down the gap at roughly a 45° angle, gently pressing the caulk into the gap as you go. As we have discovered above it is essential that you use the correct type of filler or sealant for the job at hand and although acrylic-latex caulks are great for the afore mentioned jobs, they should not be used in areas of humidity and moisture, high expansion and contraction or extreme temperature changes e.g. kitchens and bathrooms, silicone-based sealants should be used here. Perimeter gap filling around window and door frames; ideal for timber frames where woodstaining is required. Position the nozzle at the point you want the caulk to fill the gap and start squeezing the trigger of the caulk gun gently. As the caulk starts to flow move the gun and nozzle along the gap ensuring that the caulk is fully filling the gap as you move. Work slowly and methodically.Typically, silicone sealants tend to be a fair bit more flexible than caulks as they are made using silicone (flexible polymer-based substances) that are very malleable and remain flexible even once cured which makes them ideal for filling and sealing gaps in areas such as bathrooms and kitchens that are subject to extreme temperature changes and expansion and contraction and also high levels of water and moisture where they need to remain fully flexible. Dip your finger in a cup or glass of water and ensure it is wet and position it over one end of the caulk (again it’s easier to work top to bottom/left to right).

Caulking a building or property correctly can have a dramatic affect on how efficient it is in terms of keeping it water tight and air tight to prevent water and moisture creating mold, cold air entering and hot air escaping. When done correctly this can dramatically reduce heating costs and associated maintenance costs. In general a single application caulk can be used to fill gaps around 6-8mm (roughly 1/4 an inch) in width, however for any gaps wider than this a layer of caulk should be applied below the final surface level and allowed to fully cure before a final flush fill layer of caulk is applied.

General purpose latex acrylic-based caulks can be used for a wide variety of jobs in the home as it is the general purpose workhorse of fillers. Some common applications are: Many but not all liquid caulks, sealers, and patches come premixed. Dry mixes require water, followed by hand mixing until they reach the desired consistency—which could be a combination of the manufacturer’s recommendations and how runny you need it to be. It’s best to follow mixing directions as closely as possible, but you can thin the mix with a minimal amount of extra water if absolutely necessary. Unwanted Food or Drink Products - Once supply conditions are broken, there are a number of factors outside of our control that can affect the quality of a product. Therefore perishable goods such as food and drink cannot be returned. If you have a wide gap to fill you can cut the end of the nozzle to allow more caulk to flow but as our gap is only fairly slight we left the nozzle tip as it is.
