Lacrysil Household Foam (with straw applicator, all-season) is designed for quick filling, fixing, thermal and sound insulation of joints, gaps, and cavities in household repairs. It expands 2–3 times, providing excellent adhesion and stability after curing.

Recommended Applications:

• Installation of window and door frames (partial filling of joints)

• Installation of window sills, thresholds, skirting boards, moldings

• Filling gaps, cracks, cavities around frames, pipes, cables

• Fixing lightweight panels, decorative elements, shelving units

• Thermal and sound insulation of walls, floors, roofs, partitions

• Sealing openings around ventilation, electrical wiring, plumbing

• Filling gaps in walls, ceilings, floors

• Insulation and sealing in garages, balconies, loggias, utility rooms

• Minor household repairs (fixing furniture, shelves, decor)

Suitable for these surfaces:

• Concrete, brick, aerated block, foam concrete

• Cement and gypsum plasters, screeds

• Wood, chipboard, OSB, plywood

• Metal (aluminum, steel)

• PVC, plastic panels

• Glass, ceramics, tiles

• Old plaster, wallpaper (after cleaning)

Not Recommended For:

• Filling large cavities without formwork (foam may sag)

• Constant contact with water (not for waterproofing)

• Joints subject to heavy mechanical loads or constant friction

• Surfaces constantly submerged in water

• Food contact surfaces or areas with direct food exposure

• Filling joints in high-temperature zones (above +100 °C after curing)

Important Recommendations Before Application:

• Surfaces must be clean, free of dust, grease, old foam

• It is recommended to moisten the surface with water (for better curing and adhesion)

• Shake the can 20–30 times (especially before first use)

• Turn the can upside down during application

• Fill the joint to 30–50% of its volume (due to secondary expansion)

• Avoid applying to wet surfaces or during heavy rain

• Wear gloves, goggles, and work in a ventilated area

• Do not load the joint until fully cured (12–24 hours)

• Trim excess foam with a knife after 15–25 minutes (after skin formation)

Typical Usage Examples:

• Filling gaps around a window frame after installation

• Fixing a window sill and threshold

• Insulating joints in walls and floors

• Filling gaps around heating pipes and drains

• Fixing skirting boards and moldings

• Sealing openings around cables and electrical sockets

• Insulating a balcony or loggia

• Minor repairs of cracks in walls or ceilings

After full curing (12–24 hours), the foam can be cut, sanded, plastered, filled, or painted. It is non-conductive and has good thermal and sound insulation properties.
