White sealant:

How to choose it, how to use it

Wondering which white sealant to use? Our comprehensive guide will help you to choose the best white silicone sealant for the job. You’ll also find tips and tricks for getting professional results for any DIY project.

Uses for white sealant

Sealant is a DIY essential – a filler and sealant that can cover up unsightly holes and gaps, and protect your house from water damage. It also keeps out draughts, dust and insects. You can use sealant just about anywhere, from gutters to window frames, and if you use a high-quality sealant, you’re guaranteed protection for years to come.

White silicone sealant is one of the most popular products with both professionals and homeowners. It’s easy to use and more flexible than other sealants. In addition, the white colour means that it blends in nicely. The best DIY work is “invisible” – unnoticeable once it’s finished. For a seamless result, use white sealant for the finishing touches.

Applying white sealant in showers and baths

Just follow these steps to get the best results with white silicone sealant.

  1. Remove old sealant and clean the surface. UniBond Silicone Sealant Remover breaks down old sealant, making it easier to remove.
  2. Tape the borders. Use painters’ tape instead of regular masking tape, as it’s easier to remove and won’t make a mess.
  3. Prepare the sealing gun. Cut the tip of the nozzle at a 45-degree angle and insert the cartridge.
  4. Test the sealant on a disposable surface. Check the bead size and flow.
  5. Apply the sealant. Start in the corner and apply the sealant evenly along the seam.
  6. Smooth the sealant. Use a smoothing tool such as the UniBond Smoother & Cutter, which is also handy for opening cartridges.
  7. Remove the tape and wait for the sealant to dry. It usually takes about 24 hours. You can remove excess sealant using white spirit or silicone sealant remover. If the excess sealant has already dried, simply scrape it off with a utility knife, taking care not to damage the surface.

The process for applying white sealant for wood trim is essentially the same as applying sealant for other areas, such as showers and baths. The only difference is the type of sealant you use. Always check the manufacturer’s instructions to be sure that the sealant is suitable for the surface.
