Texture (WT#100) Coating SystemPolyurethane Resin Base (WT#100) Coating System
High Performance & Durable Colour Solution
Progressive Cross-linking Technology Polyurethane Resin Base (WT#100) Coating System is an especially high
performance and durable polyurethane paint for applying on new project of
government headquarter, new school, university, factory for external wall,
semi-open area of corridor as well as metal surface as stainless steel frame
etc.
With our advanced Cross-linking Technology, Polyurethane Resin Base
Coating System surpasses the durability and performance of convention
acrylic coating or polyurethane paint. The resin particles fuse together
forming a markedly durable paint as the water evaporates, providing a highly
dense coloured film for outdoor area of external wall that keeps buildings in
original condition for more than ten years.
Water Based Polyurethane Resin Base (WT#100) Coating System is
formed by a reaction between hydroxy and isocyanate compounds with
acrylic synthetic. Polyurethane Resin Base (WT#100) Coating System is
tough and abrasion-resistant, providing excellent chemical and solvent
resistance, weathering properties, gloss retention and the one-pack type
formulations are sensitive to moisture in the wet stage, with an outstanding
resistance to humidity, acids and alkali. Product Description

less than 10
1.2 Application surface must be smooth and free of voids or sharp projections.
1.3 Any application surface such as precast concrete, with
excess pinholes, honeycomb, cracks, uneven or porous condition, should be filled up prior to the application.
1.4 Any application surface, with laitance, efflorescence, dust,
rust, oil grease, curing agent etc. must be removed completely by brushing, sanding or other effective means.

2.4 Application Method
Use roller or spray Mask all adjacent areas Remove all over-spray immediately
2.5 Application Technique Unrolled Texture
• Keep the gun nozzle at a distance of two (2) feet from the surface to be sprayed. • Spray texture compound with the gun nozzle at a right angle to the surface to be sprayed
• Best results are achieved by confining length and height of spray area to the body dimension of applicator (i.e. height of reach and width of arm spread), continuing with additional spray areas until the application surface has been completely coated.
• Plan spray work to finish at a joint line at the end of work period. (Note: Do not overlap previously sprayed dry compound.)

requirement. Brush may be used for small areas or touch up only. Drying time may take within four (4) hours at 20°C Workers, applying surfacer in confined areas, are required to wear protection masks and
exhaust ventilation should be properly supplied to the confined area. 4 Topcoat

Texture (WT#100) Coating SystemPolyurethane Resin Base (WT#100) Coating System Remarks
1 The recommended coverage rates, including those of normal wastage, are for reference only. Actual coverage may vary depending on the working condition of the site, the degree of evenness and smoothness of the substrate surface, and the pattern of the texture sample as selected and approved by the architect or client.
2 We reserve the right to change or adjust the composition of material used in the specification of our products due to our constant research and development to improve the quality of our products
Storage Requirement
In order to ensure product integrity prior to the application, it is mandatory to comply with the following requirements of storage:
Store materials away from open flame or excessive heat. Do not expose the material to sunlight for a long period of time. Keep all containers away from moisture Do not expose materials to freezing conditions. Keep containers air-tightly sealed.
