Lacrysil "2 in 1" Acrylic Sealant-Adhesive (also known as "Stronger than Nails" / "Tougher than Nails") is designed for simultaneously bonding and sealing joints, cracks, and gaps. It forms a crystal-clear, strong, and elastic seam that does not tear, does not yellow over time, and prevents the penetration of air, moisture, and dust. It is ideal for work where an invisible seam is needed (glass, plastic, wood, transparent surfaces).

Recommended Applications:

• Sealing and bonding gaps and joints in windows, doors, insulated glazing units

• Sealing joints around window sills, thresholds, skirting boards, moldings

• Fixing and sealing decorative elements, baguettes/cornices, stucco molding, panels

• Filling gaps between furniture, walls, and floors

• Sealing joints in furniture, shelving units, shelves

• Sealing joints around pipes, cables, electrical sockets, switches

• Bonding and sealing plastic, glass, wooden, and metal elements

• Preventing drafts and moisture in gaps (windows, doors, balconies, terraces)

• Repairs and finishing in residential, office, and commercial premises (interior work)

• Minor repairs of furniture, decor, interior elements

Suitable for these surfaces:

• Glass and mirrors

• Plastic, PVC, polycarbonate

• Wood, chipboard, plywood, OSB

• Metal (aluminum, steel, galvanized)

• Ceramics, tiles

• Concrete, brick, plaster, drywall

• Laminate, linoleum, vinyl flooring (for small joints)

Not Recommended For:

• Joints with constant water immersion (swimming pools, bathtubs, showers — use silicone or MS polymer sealant instead)

• Aquariums or potable water tanks

• Surfaces constantly submerged in water or in aggressive chemical environments

• Joints subject to heavy mechanical loads or constant friction (use MS polymer or silicone)

Important Recommendations Before Application:

• Surfaces must be clean, dry, free of dust, grease, old sealant, or detergents

• It is recommended to degrease with alcohol or acetone (especially glass, metal, plastic)

• For better adhesion on porous surfaces (concrete, plaster, wood) — pre-prime with an acrylic primer

• Do not apply to damp or very wet surfaces

• Avoid application during high humidity or rain

Typical Usage Examples:

• Sealing and fixing the joint between an insulated glass unit and the frame (to prevent drafts)

• Sealing gaps around window sills and thresholds

• Bonding and sealing decorative moldings and baguettes/cornices

• Filling cracks in furniture, shelving, shelves

• Sealing joints around electrical sockets, switches, cable channels

• Fixing lightweight panels, skirting boards, decorative elements

• Eliminating small gaps between the wall and furniture or skirting boards

After full curing (24–48 hours depending on layer thickness and humidity), the seam remains transparent and can be painted with acrylic paints (if a color change is needed).
