Based on special acrylic resins, it features excellent thixotropic properties — tiles adhere immediately without slippage. Once cured, it offers outstanding flexibility and bonding strength, able to withstand vibrations and deformations in building materials. Especially recommended for flexible, deformable non-metallic substrates.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\u003cli\u003eReady to use — no water or mixing required, apply directly from the bucket, saving preparation time\u003c\/li\u003e\u003cli\u003eNon-slip — excellent thixotropic properties keep tiles stable immediately after placement on vertical surfaces\u003c\/li\u003e\u003cli\u003eExtended open time — generous working time (per manufacturer data) for precise tile positioning\u003c\/li\u003e\u003cli\u003eHigh flexibility — excellent deformability after curing, accommodates minor substrate movement and vibration\u003c\/li\u003e\u003cli\u003eWide substrate compatibility — suitable for plywood, gypsum board, painted surfaces and other special substrates\u003c\/li\u003e\u003cli\u003eEasy application — white paste consistency, easy to trowel, tools clean with water\u003c\/li\u003e\u003c\/ul\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cul\u003e\u003cli\u003eIndoor wall, floor and ceiling installation of all types of ceramic tiles and mosaics\u003c\/li\u003e\u003cli\u003eOutdoor wall installation of ceramic tiles and mosaics\u003c\/li\u003e\u003cli\u003eBathroom and shower room walls and floors\u003c\/li\u003e\u003cli\u003eMoisture-resistant plywood (wood substrates must be stable and moisture-proof)\u003c\/li\u003e\u003cli\u003eCement renders and concrete substrates\u003c\/li\u003e\u003cli\u003ePrecast or cast-in-place concrete walls\u003c\/li\u003e\u003cli\u003eGypsum plaster, gypsum board\u003c\/li\u003e\u003cli\u003eStable painted wall surfaces (paint must be firmly bonded and tiles must be absorbent)\u003c\/li\u003e\u003cli\u003eOver-tiling on existing ceramic tiles (at least one surface must be absorbent)\u003c\/li\u003e\u003cli\u003eLarge-format tiles\u003c\/li\u003e\u003cli\u003eUnderfloor heating systems\u003c\/li\u003e\u003cli\u003eBonding of thermal and acoustic insulating panels\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eNot Suitable For\u003c\/h3\u003e\u003cul\u003e\u003cli\u003ePermanently submerged areas (swimming pools, water features, etc.)\u003c\/li\u003e\u003cli\u003eSubstrates subject to rising damp\u003c\/li\u003e\u003cli\u003eNon-absorbent tiles on non-absorbent substrates\u003c\/li\u003e\u003cli\u003eMetallic substrates or non-moisture-stable wood substrates\u003c\/li\u003e\u003cli\u003eNatural stone (especially light-coloured calcareous stone such as Carrara marble)\u003c\/li\u003e\u003c\/ul\u003e\u003ch2\u003ePackaging\u003c\/h2\u003e\u003cul\u003e\u003cli\u003e16 kg plastic bucket\u003c\/li\u003e\u003cli\u003e12 kg plastic bucket\u003c\/li\u003e\u003cli\u003e5 kg plastic bucket\u003c\/li\u003e\u003cli\u003e1 kg plastic container (12-piece pack)\u003c\/li\u003e\u003c\/ul\u003e\u003ch2\u003eStorage\u003c\/h2\u003e\u003cp\u003eShelf life in original sealed packaging — refer to packaging label.
