Preparing substrates to receive resin coating

  • CONCRETE FLOORS

    Concrete Industrial ground floors consist in a mixture made up of aggregate (25/30mm maximum particle size in specific curve), cement, water, iron (either mesh or fibers), additives (mainly acting as water reducers, but not only), which after curing serves as a foundation (the lowest supporting layer) and a finish for all kinds of factories, storage and sorting warehouses, forecourts, raised floors, and so on.

    When placed directly on an underlaying concrete casting, it is called BONDED FLOOR.

    if, instead, it is suspended on a previously laid separating layer it is called FLOATING FLOOR.

  • SCREEDS

    The screed is a support layer usually made of sand and cement or gypsum, which acts as a setting bed for subsequent tiling, wood, carpet, linoleum and PVC, resins, etc.

    If the screed layer is laid ​​directly on top of the underlaying concrete slab it is called "BONDED SCREED"; if, on the contrary, before laying it an insulating layer consisting of either insulating panels or insulating screeds or a separator layer is laid on top of the underlaying concrete slab, then it is called "FLOATING SCREED"

  • PLASTER

    Plaster is a mixture of sand with small grain size, size usually less than 3 mm, in specific curve, lime, cement, water and additives having the main function of both water reducers and retainers.

    After curing plaster is used as a smooth substrate for the installation of either thin-film finishes (paint) or thick coatings (exterior plasters) or also for ceramic and resin coatings.

  • CERAMIC COATINGS AND STONEWARE

    These are coatings especially designed for floors formed from Ceramic, Stoneware and Clinker tiles, and from honed marble/cement Tiles or variously finished cement Tiles and so on, and are glued-down to a substrate generally consisting of a sand and cement screed.

    According to the old tiling method, still existing in buildings constructed until the 70s, Ceramic tiles, Stoneware and Marble tiles were directly glued down to a fresh substrate, therefore are jointless.

    On the contrary, according to the most recent way to lay down tiles, the materials generally used are Ceramic, Porcelain Stoneware and Clinker with tiles of a larger size that are laid down with adhesive and separated by joints, to allow a better expansion absorption, which later are to be filled with cement-based plasters (COLORFILL FLEX ).

  • NATURAL STONE COATINGS
  • RESIN SURFACES (to be covered with resins)

    These are resin coatings to be installed over other existing resin coatings, that are laid down to protect screeds, industrial concrete, natural stones like marble and granite, tiles etc.
