91 000 74051 LATAPOXY 300 is a chemical-resistant, 3-component epoxy adhesive (resin + hardener + silica-filler) for tiles, stone, mosaics, etc.It's part of the same family as LATAPOXY 310 (which you asked earlier), but 300 is more a general-purpose epoxy tile/stone adhesive rather than a "spot-bonding" adhesive only. It meets international standards for epoxy adhesives (e.g. EN 12004 / ISO 13007 with Classification "R2").
�� What it's Used For — Typical Applications
You can use LATAPOXY 300 for:
Installing ceramic tiles, natural stone, marble, mosaics, resin-backed tiles, agglomerated stone on floors & walls — both interior and exterior (within recommended limits).
Areas that require chemical resistance or heavy-duty installation — like kitchens, commercial spaces, industrial floors, food-processing areas, or any place prone to spills/chemicals.
Surfaces including concrete, cement beds/mortar, masonry, brick, cement plaster, terrazzo, existing tile/stone, metal, cement backer-board, gypsum board (interiors only), plywood (with care) etc.
Situations where you need water-cleanable adhesive (no solvent), high bond strength, non-staining for light-coloured stones/marbles, durable bond (wet, dry, submerged, or exposed to chemicals).
✅ Key Features & Advantages
Chemical-resistant & durable — good for heavy duty, commercial, industrial or chemically exposed floors/walls.
Water-cleanable (no flammable solvents) — safer and easier to clean tools while fresh.
Pre-proportioned 3-part kit — resin, hardener, filler, ready to mix.
Non-staining on white or light-coloured marble/stone — important when using expensive or light-coloured natural stone.
Very strong bond and versatile substrate compatibility (concrete, plaster, masonry, steel, tiles, existing floors, etc.)
⚠️ When to Use — And When to Avoid
Use LATAPOXY 300 when:
You need maximum strength, chemical resistance, or durability (industrial kitchens, commercial spaces, exposed floors, chemical-resistant zones).
You're installing marble / natural stone / resin-backed tiles — especially moisture-sensitive or light-coloured stones.
Substrate is concrete/masonry/metal or otherwise demanding.
You might avoid or choose differently if:
You just want a simple tile installation in a regular residential area without exposure to chemicals or heavy load — then a standard tile-adhesive (cement-based or simpler polymer adhesive) might be sufficient and more economical.
You expect heavy structural movement or flex (epoxy adhesives are rigid; if there's movement you may need flexible adhesives or special substrate prep).
The installation involves very small or simple jobs where epoxy bonding is overkill.
