Application Instructions
l Substrate preparation:
(1) For application onto newly resin-coated surfaces, the underlying resin coating must be fully cured and dry, with topcoat application carried out within 24 hours. If exceeding the 24-hour window, the resin substrate shall be thoroughly cleaned and completely free from oil, grease and all surface contaminants. Mechanically abrade the surface with a single-head floor sander fitted with 200–300 grit abrasive paper or a fine-grade abrasive pad. Upon completion of mechanical preparation, remove all dust residues by thorough vacuuming to guarantee optimal coating adhesion.
(2) For substrates of cementitious materials, apply YHFloorSeal PW only after the cementitious substrate has fully cured (minimum 24 hours, subject to layer thickness and ambient temperature). Perform light sanding beforehand, then fully vacuum away all sanding dust. In all cases, a suitable primer must be applied prior to top coating to regulate the substrate’s absorbency.
(3) For new or existing concrete surfaces, ensure the substrate is thoroughly cleaned and free from oil, grease and other contaminants prior to application. Complete thorough surface sanding, followed by industrial vacuum cleaning to eliminate all dust and ensure proper finish adhesion. In every case, apply the topcoat only after priming for effective pore sealing.
l Mixing: Mix Component A with Component B using a low-speed electric mixer until fully homogeneous, mixing only the amount that can be applied within the maximum pot life. If a non-slip finish is required, add 3–5% by weight of quartz (80-100 mesh) sand during mixing.
l Coating application: Apply 1–2 coats of YHFloorSeal PW using a short-pile roller or airless spray equipment. When applying by roller, work in two perpendicular directions. If the over-coating interval between successive coats exceeds the time recommended in the above table, lightly sand the surface of the previous coat, then thoroughly remove sanding dust by vacuum before applying the next coat. Over-coating times are shorter at high temperatures and longer at low temperatures. Ensure the area is well ventilated to facilitate drying.
TRANSPORTATION AND STORAGE
The product should be stored in ventilated areas, protected from sunlight, rain, and fire. Avoid collisions during transportation. The recommended storage temperature range is 12°C to 30°C. The shelf life is a minimum of 12 months under normal transportation and storage conditions.
YHFloorSeal PW is an ideal topcoat for resin flooring systems. The product is also suitable for the surface protection of concrete substrates.
