Common Caulking FAQS

Caulking is a process of sealing gaps or joints in various surfaces using a waterproof filler material, typically made of silicone or polyurethane, to prevent air, water, sound, or dust infiltration. For all your caulking needs, Eastern Sealant Services is your go-to!

Caulk usually takes 24 hours to fully cure but this can vary depending on the temperature and humidity.

  1. Mix equal parts white vinegar and water in a spray bottle.
  2. Spray the mouldy caulk generously.
  3. Let it sit for 10-15 minutes.
  4. Scrub with an old toothbrush or scrub brush.
  5. Rinse with clean water and repeat if needed.
  6. Ensure the caulk is thoroughly dry.

Silicone and rubber caulk are porous so deeply embedded mould can sometimes completely penetrate the material. If black stains persist after cleaning, the mould has likely breached the seal. For a long-term solution, contact Eastern Sealant Services to remove the old caulk and apply a fresh bead of silicone.

Gently scrape away old caulk with a caulk removal tool or putty knife and then thoroughly clean the surface. For professional results, contact Eastern Sealant Services.
