Before installing the profile, the surface shall be cleaned of dust, oils, and other contaminants. SPEKTRON PROF-BNT can be installed on a smooth concrete surface or in a pre-prepared groove.
Cement laitance and other contaminants shall be removed from the substrate surface using a wire brush or a spatula.
Surface leveling can be performed by smoothing freshly placed concrete using a trowel or float. In the case of hardened concrete, the surface can be leveled using SPEKTRON GTS sealant. In this case, the installed profile shall be positioned in the center of the concrete element. The recommended distance from the edges shall be at least 100 mm.
