Sealing a bathtub is not a difficult job, but great results are a lot easier with our tips for success. Read on to find our recommended materials and techniques.
Use silicone or siliconised latex sealant for sealing a bathtub
A leakproof seal around the bathtub is essential to keep water from seeping into the wall cavity, thus causing major damage and leading to mould, stained walls and ceilings, and eventually rotted wood.
Don’t let this happen in your home! Make sure the bath seal is sound, clean, and doing its job. If you have just remodelled and need to seal a new bathtub, read the next section for instructions.
If you want to freshen up the bathroom because the old bathtub sealant is showing its age, we have instructions for that as well.
Clean the surface thoroughly before sealing a bathtub, so the sealant adheres properly
For sealing a new bathtub, follow these easy instructions:
- Make sure the surface is clean and free of dust or any residue.
- Cut the tube of sealant at a 45° angle and puncture the seal if needed.
- Squeeze the tube and apply an even bead along the seam.
- Use a sealant tool or your moistened finger to smooth out and feather the edges of the sealant.
- Clean up tools and hands immediately with soapy water.
Resealing an old tub follows the same process once the old sealant is removed.
How to remove bathtub sealant and reseal a bath
- Carefully scrape away at the old sealant while being careful not to damage the surface. You can buy a sealant removal tool to make the job easier. It consists of two blades set at a 90° angle so you can scrape both sides at once.
- After the majority is gone, use a cloth and solvent to remove the remaining residue. Try vinegar or alcohol first. If something stronger is needed, use an oil-based spray lubricant or a commercial sealant remover.
- Follow the same process as sealing a new bathtub.
