Whether it’s a kitchen or bathroom splashback, waterproofing is important to ensure that there is no moisture coming in to the surface that will cause rotting or damping to the build-up. If waterproof seal is not adequately applied, regular exposure to liquids and water can result to damages on what’s beneath the splashback area.
If you have the right products, it can actually save you less hassles in the long run, as some sealants are prone to discoloring and molds. To efficiently waterproof a splashback area, you need to secure a silicone sealant, which contain anti-fungal agents that prevent mold from growing despite high humidity levels in the environment you need to waterproof. Silicone sealants are low maintenance products and are easy to apply. However, it is advisable to apply the sealant with a cartridge gun to reduce unwanted mess and achieve a cleaner kitchen or bathroom splashback finish.
The silicone sealant cartridge has a nozzle which you need to cut a little first. A suggested width is 5mm cut at 45 ° angle, which corresponds to the line you will have with the sealant gun to waterproof the splashback area. Ensure that you begin by tweaking the trigger on the sealant gun gently to prevent too much coming out too quickly. Always apply the sealant towards you and never away from you. If you do it away from you, the sealant can get a smutch and the finish will be too messy.
Don’t worry too much of rejoining the sealant line; you will have a chance to finish waterproofing and cleaning the splashback area. Once you are done with applying the sealant, use a water spray with water and a bit of washing liquid to spray to the sealant. Cut a 45° angle of cardboard you will use to apply gently while scraping the excess of the newly applied sealant. This of course will leave a nice wonderful finish. For finishing touches, wet your finger with water and liquid soap and gently run the surface of the sealant. You need to push the groove neatly. So there you go – a nice application of waterproofing on your bathroom splashback.
