How to ensure that a tile adhesive spreads easily and holds up when positioning the tiles? What does it take for a correct adhesive application? The answer lies in optimizing rheological properties of systems to achieve the thickness and workability together with control of sag, hold up and creep of the wet adhesive. Control of its application is essential to ensure its final mechanical and adhesion properties. The applicability of aqueous adhesives via a notched spatula is very dependent on the ability of the adhesive to flow under stress. Thus, the rheological approach is relevant to physically describe the flow mode of these soft solid viscoelastic materials that need to be applied with a high, regular and homogeneous thickness on different substrates. The objective is to identify the rheological parameters that best describe the applicability of these thick aqueous adhesives. We will characterize the resistance to crushing when placing the tiles and its capacity to repositioning if necessary, the initial grab and sliding resistance, comparing various acrylic thickeners.
