Pokraskin For flooring, the laying of tiles and carpeting, a wide array of different types of physically and chemically setting adhesives is available [14, 15].
8.3.1.1 Adhesive Mortars for Tiling
Approximately 90% of the adhesives used for tiling are cement-based adhesive mortars. These consist of cement as the main binder, and additives such as sand fillers, plastics powders as adhesion promoters which also increase the flexibility, as well as special agents such as anti-foaming, wetting and thickening agents. When water is added to the cement mortar, it chemically sets by a ‘hydraulic’ reaction. Once cured, mortars are water-resistant.
New fast-setting adhesive mortars have significantly increased the working speed with such materials, from 24 h of setting time to as little as 2h. Polymer-based tile adhesives are chemically setting products based on PU or epoxy resin bases, typically consisting of an A-component with fillers, and a B-component without any fillers. Depending on the desired field of application, PU or epoxy resin tile adhesives may be formulated to cover a large range of properties, from rigid to soft-elastic. Reactive resin products are preferably used for heavy-duty applications, such as commercial floorings exposed to a high level of mechanical stress, including forklift traffic.
Dispersion-type tile adhesives typically comprise styrene-acrylate dispersion binders, fillers such as chalk and silica sand, and additives such as thickeners and preservatives, defoaming and wetting agents. These ready-to-use adhesives cure physically by drying. As no mixing is required, tiling may take place under clean conditions, without any need for safe disposal. Dispersion adhesives are therefore particularly
well suited to renovation purposes, for the installation of skirting boards, trimmings, etc., or for do-it-yourself work. The higher price of these types of product is balanced by the faster working speed.
