ProCote TOP is used for skim coating interior walls and ceilings in a thin 1–5 mm layer to produce a high-quality, smooth finish. It is especially effective on low-suction surfaces like plasterboards, concrete, precast panels or cement renders requiring superior decorative results.
ProCote TOP is suitable for plasterboards, smooth concrete blocks, precast panels, and cement-render backgrounds. It is specifically designed for low suction surfaces where traditional plasters struggle to adhere and perform. Ensure substrate is clean, dry, and structurally stable before application.
Often yes. Due to its excellent paint adhesion and white surface finish, ProCote TOP may eliminate the need for primer in many decorating situations. However, if using high-gloss paints or critical decoration schemes, it is recommended to test or optionally apply a primer per paint manufacturer’s advice.
Apply between 1 and 5 mm of ProCote TOP depending on the substrate and finish required. For hairline crack concealment and final decorative finishes, 1–2 mm is typical. Thicker applications up to 5 mm are possible where surface irregularities require more build.
One 20 kg bag of ProCote TOP covers approximately 20 m² at 1 mm thickness. Coverage reduces as thickness increases or if substrate suction varies. Estimate carefully and allow for wastage. Mix and apply according to instructions to maximise yield.
Drying time depends on ambient conditions, substrate and thickness. Usually allow 1-3 days before light sanding and decoration. Good ventilation and controlled humidity speed drying. Ensure full drying to prevent finish problems or premature decoration.
Yes, ProCote TOP is formulated for low shrinkage and improved adhesion, making it excellent for avoiding hairline cracking. Its fine texture and compatibility with low-suction substrates help maintain a stable, smooth surface ready for decoration.
No. ProCote TOP is specifically formulated for interior use only. It is not designed for exterior exposure or areas with continuous moisture ingress. Use dedicated exterior plasters or systems for outdoor or high-moisture environments.
No special tools are required beyond standard trowels or finishing equipment. A wide steel trowel for smoothing and optional mechanical mixers speed the process, but manual application is fully suitable. The key is correct substrate preparation and timely finishing.
Store unopened bags in a clean, dry area on pallets and away from direct sunlight or moisture. Once opened, use quickly. Good storage conditions help maintain performance, mixing consistency and finish quality for interior skimming work.
