VELVET DECO PREMIA COARSE

SUBSTRATE PREPARATION

• The substrate should be properly prepared (thoroughly dry, sufficiently stable and free of dust, grease, loose materials etc.). If the substrate is rough and not sufficiently flat, it should be smoothed/ smoothed by using MARMOLINE FLOW SL 500 self-levelling floor screed.

Application of the base coat:

• Prime the substrate using MARMOLINE PRO CONTACT quartz adhesion primer. Apply VELVET DECO FLEX base coat mortar as a filling and levelling base coating in a single layer (once the primer has dried, at least 2 hours after).
• Primer consumption: 200 – 300 gr/m2.
• VELVET DECO FLEX is gradually added to water under continuous stirring, until a suitable mixture is formed. Applied using a 10 mm notched trowel, while the 160 gr/m2 fiberglass mesh is placed and embedded with the smooth side of the trowel. (For curved surfaces, is suggested to use fiberglass mesh weighing 58 gr/m2.) Make sure that the fiberglass mesh strips cover each other by 10 cm.
• For particularly flat substrates, instead of the VELVET DECO FLEX, VELVET DECO PREMIA COARSE can also be used as a base coat mortar and can be applied with a 6mm notched trowel. In this case, a 58 gr/m2 fiberglass mesh is placed and embedded with the smooth side of the trowel

Application of the finishing coat:

• After the application of the base coat, VELVET DECO PREMIA COARSE is used as finishing coat layer, in grain size thickness, to fully cover the fiberglass mesh. VELVET DECO PREMIA COARSE is applied with a smooth, stainless-steel trowel, in one or two layers with a maximum thickness of 1-2 mm each.
• After 24-48 hours, providing the surface should be thoroughly dry (using a suitable moisturemeter check that moisture is less than 5%, or else problems may occur in application), the protective varnish should be applied. Check the substrate is clean and then apply, either the MARMOLINE VELVET LIQUID PU, 1k polyurethane varnish or the MARMOLINE VELVET AQUA PU, 2k water-based, polyurethane varnish, which is the ideal solution for indoor applications. The varnishes applied using roller, brush or via spraying. It is recommended to apply two coats, crosswise, observing the waiting time between them (~ 24 hours) with a consumption of 100-120 g/m2 per coat.
