Lacrysil Professional Adhesive Foam (for gun application, all-season) is designed for quick, strong, and precise fixation of materials without additional mechanical fasteners. Thanks to its high initial adhesion, low secondary expansion (15–30%), and stability, it is ideal for the professional installation of insulation, panels, structures, and large areas.

Recommended Applications:

• Bonding thermal insulation boards (expanded polystyrene, extruded polystyrene, Styrofoam, mineral wool) to facades, walls, floors, roofs, plinths

• Fixing OSB boards, chipboard, plywood, drywall, gypsum fiber boards to walls, ceilings, frames, partitions

• Installation of sandwich panels, facade cassettes, decorative panels, ventilated facades

• Fixing window sills, thresholds, stair flights, skirting boards, large-format moldings

• Bonding drywall sheets, MDF panels, laminated boards, acoustic panels

• Installation of lightweight partitions, shelving units, shelves, temporary structures

• Insulation of facades, roofs, floors, balconies, loggias, industrial premises

• Work with underfloor heating (fixing materials before screed pouring)

• Professional insulation and finishing in residential, commercial, and industrial facilities (interior and exterior work)

• Fixing materials in "dry screed," "floating floor," and "floor insulation on joists" systems

Suitable for these surfaces:

• Concrete, brick, aerated block, foam concrete

• Cement and gypsum plasters, screeds

• Wood, chipboard, OSB, plywood

• Drywall, gypsum fiber board

• Metal (aluminum, steel, galvanized)

• PVC, plastic panels

• Old tiles, porcelain stoneware, concrete blocks

• Expanded polystyrene, Styrofoam, mineral wool (to each other and to the substrate)

Not Recommended For:

• Filling large cavities or joints (use regular polyurethane foam instead)

• Constant contact with water or in aggressive environments (not for waterproofing)

• Very heavy structures without additional fixation (load over 100–150 kg per element — combine with mechanical fasteners)

• Surfaces constantly submerged in water

• Food contact surfaces or areas with direct food exposure

• Areas with temperatures above +100 °C after curing

Important Recommendations Before Application:

• Surfaces must be clean, dry or slightly damp, 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

• Turn the can upside down during application

• Apply in strips, zigzags, or dots to the material or substrate (do not fill the joint completely — due to expansion)

• Press the material for 60 seconds for fixation (adjustment possible within 3–5 minutes)

• Do not load immediately — allow to cure for 12–24 hours

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

• Trim excess foam with a knife after 3–5 minutes (after skin formation)

• Use a professional foam gun for precise dosage, output control, and material economy

Typical Usage Examples:

• Bonding insulation (expanded polystyrene or mineral wool) to a facade before reinforcement and plastering

• Fixing OSB boards or drywall to a wall/ceiling without additional dowels

• Installing sandwich panels on facades or partitions

• Fixing large-format window sills and thresholds

• Insulating roofs or floors (fixing materials)

• Quickly fixing temporary structures, formwork, scaffolding

• Installing acoustic panels or decorative elements

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