Bostik General Purpose Neutral Cure Silicone Sealant 20ml – Clear, Flexible & Waterproof

Description

Overview

This high-quality general-purpose silicone sealant is a versatile solution for a wide range of sealing and bonding applications. Engineered with neutral cure technology, it is designed to provide a durable, flexible, and weather-resistant seal that remains reliable even in demanding environments. Once cured, the sealant forms a strong rubber-like finish that is permanently elastic, ensuring long-lasting performance both indoors and outdoors.

Key Features

  • Neutral Cure Technology: Low-odor curing system suitable for sensitive applications.
  • Permanently Flexible: Retains elasticity over time without cracking or shrinking.
  • Waterproof Protection: Provides a watertight seal, protecting against leaks and moisture ingress.
  • Interior & Exterior Use: Unaffected by rain, snow, extreme temperatures, or prolonged UV exposure.
  • Excellent Adhesion: Bonds strongly to most common building materials without primer.
  • Easy Application: Smooth flow from the tube, easy to tool and clean before curing.

Applications

This sealant is designed for general-purpose use across a variety of materials and environments. Its flexibility and adhesion make it suitable for:

  • Sealing around window and door frames.
  • Lap joints in metal guttering and roofing sheets.
  • Bonding panels such as wood, plasterboard, insulation board, and drywall.
  • Fixing masonry joints including sills, brickwork, and decorative trims.
  • Gap filling around pipes, conduits, and penetration surfaces.
  • General sealing in kitchens, bathrooms, and living areas where flexibility is required.

Limitations

  • Not suitable for permanent water immersion (e.g., underwater joints or continuous water load).
  • Not recommended for use on polyethylene (PE), polypropylene (PP), polycarbonate (PC), polymethyl methacrylate (PMMA), PTFE, neoprene, bituminous surfaces, or very soft plastics.
  • Not intended for deep cavity filling without adequate moisture for curing.

Surface Preparation

To ensure maximum performance, surfaces must be clean, dry, and free from dust, grease, or loose particles. Non-porous surfaces should be wiped with solvent and dried with a clean cloth. Porous surfaces should be lightly abraded or brushed to remove contaminants and improve adhesion. Complete any painting work before applying the sealant.

Application Instructions

  1. Remove the cap and pierce the nozzle seal.
  2. Apply steadily along the joint or surface, ensuring continuous contact.
  3. Smooth or tool the bead before skin formation occurs.
  4. If masking tape is used, remove immediately after tooling to avoid tearing the cured seal.

Curing

At room temperature (23°C), the sealant will skin over within 15 minutes and achieve full cure within 24 hours, depending on humidity and joint depth. Once cured, it provides a permanently flexible and weatherproof joint.

Cleaning & Maintenance

Excess uncured sealant can be cleaned using a cloth dampened with mineral turpentine. Fully cured material should be trimmed away carefully with a sharp blade. Store unused tubes in a cool, dry place below 25°C and away from direct sunlight. Shelf life is up to 12 months from the date of manufacture.

Health & Safety

Use in a well-ventilated area. Avoid contact with eyes and mucous membranes, as uncured sealant may cause irritation. In case of contact with eyes, flush thoroughly with water and seek medical advice. Keep out of reach of children. Always follow safety instructions and refer to the product’s safety data for detailed guidance.

Why Choose This General Purpose Silicone Sealant?

This sealant is a trusted choice for tradespeople, DIY enthusiasts, and homeowners seeking a reliable solution for everyday sealing needs. Its combination of flexibility, adhesion, and weather resistance ensures that once applied, it continues to protect and bond effectively for years to come. Whether you are fixing a leaking gutter, sealing around windows, or bonding decorative trims, this product provides professional results with minimal effort.
