MasticPrep™
Professional Silicone, Mastic & Sealant Removal Tool
Mastic removal tool MasticPrep™ is a purpose-built V-groove oscillating multi-tool blade designed to remove silicone, mastic, sealants and decorators’ caulk quickly, cleanly and accurately from internal corners and joint lines. Developed from real on-site experience, it helps tradespeople prepare surfaces for resealing while reducing damage to surrounding finishes.
Unlike standard oscillating blades, MasticPrep™ has been specifically engineered for controlled sealant removal. Its precision V-groove cutting profile follows internal corners, making it easier to remove old silicone, mastic and sealants while creating a clean, consistent joint ready for resealing.
Suitable for professional installation, maintenance, refurbishment and remedial works, MasticPrep™ is ideal for joiners, window and door installers, kitchen and bathroom fitters, decorators, maintenance contractors, passive fire professionals and general tradespeople who require fast, accurate sealant removal.
Whether you’re removing bathroom silicone, window sealants, fire-rated mastic, decorators’ caulk or construction sealants, MasticPrep™ helps improve preparation, increase productivity and deliver a cleaner professional finish
