Did you know that you can use CT1 sealant and adhesive to fill large gaps as well as small ones?
Often objects in our home might not be as flush with our walls as we hope them to be. Fitted wardrobes, kitchen units, or even custom-built carpentry might have gaps up to an inch deep that you think are too big to seal up. However, there is a great trick you can use to seal these gaps effectively.
But why should you choose CT1 sealant and adhesive for the job? CT1 is the world’s leading construction adhesive and sealant with over 25 accreditations to its name. It uses revolutionary TRIBRID® technology that makes it incredibly safe for use in the home. In fact, it’s even been backed by the NAAF (The Norwegian Asthma and allergy association) as it can be used with no risk of causing asthma or allergy attacks.
CT1’s unique TRIBRID® technology formulation is so scientifically enhanced that it outperforms all other sealants and adhesives, making it the best choice for a fantastic, long-lasting finish. And, with higher colour retention too, you can be certain that your seals and repairs will look great for longer.
How to seal a big gap
First, you’ll need some backer rod. This is available in multiple sizes, so measure the width of your gap and then choose the size which will fit best. It needs to be snug in order for the sealant to achieve a successful finish. Push the backer rod into the entirety of the gap. It should be about 1/8th inch deep and completely uniform.
Now, if you want to protect any surfaces from getting sealant on them, use masking tape. This is also a great technique to get a perfectly straight line on your finish. It takes a little bit longer to set up, but the results can really be worth it.
Once the backer rod is in place and your masking tape is ready, you’re ready to apply your CT1. As you’re filling a wide gap, you may want to cut the nozzle’s tip wider than usual, or you can apply extra pressure to the caulking gun to squeeze out more sealant.
Apply a thick amount of sealant, overfilling the gap slightly, as it will move into the space when you smooth it down. As the gap is wider than usual, smoothing in the sealant with your finger won’t do. Instead, take a filling knife or putty knife and line it up with your flat surface. Keep it square as you drag it along, pressing firmly to ensure that the sealant adequately fills the gap and simultaneously removes any excess. Repeat this until you have a clean, smooth finish.
Be careful that you don’t dig your knife in at corners. You’re trying to get a completely flush finish, so keep your knife pressed flat to the solid surface and adjust the angle where needed.
