Window caulking, which involves sealing the edges of windows with a waterproof sealant, is a relatively simple task, but has many benefits. Proper caulking can protect your home from moisture infiltration, drafts and heat loss for many years to come.
However, in order to enjoy the benefits of tightly sealed window edges, these 5 common mistakes must be avoided when caulking your windows.
Not removing the old sealant before applying a new one
Over time, sealant tends to harden and detach from the surface on which it was applied. If you don’t remove the old sealant properly, water and moisture can seep in.
Use a putty knife or sharp tool to remove it, then clean the surface with 99% rubbing alcohol. Once the surface is clean and dry, you can start applying the new sealant.
Not choosing the right sealant
For long-lasting protection around your windows, choose a neutral silicone that is 100% silicone or hybrid and latex-free. These types of sealants are waterproof, flexible, shrink-resistant and have a life span of nearly 20 years.
This type of caulking product can easily be found in hardware stores. Please note, however, that silicone sealant cannot be painted.
Using the wrong caulking gun
Sealant cartridges available at hardware stores are generally not designed to be used as an application tool. You will need a caulking gun that is compatible with the size of your cartridge to apply the sealant correctly.
Cheap guns tend to apply the sealant unevenly, which gives the impression that the work was done poorly. You should therefore choose a professional model with a comfortable grip. With a good tool, your work will be easier and your windows will be properly sealed.
If the crack you are sealing is more than 1 cm wide or 1 cm deep, you should resist the temptation to add more sealant. Instead, fill the space with a flexible backing foam to fill the space before caulking. You will get a much better result.
Forgetting to shape the sealant after application
Shaping consists of smoothing the sealant after its application. This important step ensures that the final result looks neat and professional. After applying a line of sealant, run your finger or a wooden stick along it to make sure it fills the opening.
