Product Introduction

Description

PU coating is available in a range of formulations that are tailored to specific needs, making it suitable for a wide range of applications. This includes both solvent-based and water-based options, as well as different viscosities and levels of viscosity.

Overall, the versatility and effectiveness of polyurethane waterproof coating has made it a popular choice for waterproofing projects around the world. Its ability to seal out moisture and provide durable protection against a range of environmental factors makes it an ideal choice for projects of all sizes, from residential to industrial construction.

Feature

PU coating has physical properties of high strength, high elongation, high solid content and strong adhesion. Secondly, the natural leveling and good elongation can overcome the leakage caused by the cracking of the base.

Specification

Color	Pail	Coverage	Packing
Red, Grey, Black, Green	20kg/pail, neutral packing or OEM	1.65kg/sqm, 1mm thickness	Plywood Pallet

Application

1. Roof: All kinds of old and new flat-sloping roofs and gutter cornices, especially suitable for waterproof and seepage prevention of irregularly shaped parts.

2. Ground construction: waterproof and moisture-proof finishes for toilets, bathrooms, kitchens, pools and exterior walls.

3. Underground buildings: inner and outer walls, floors, underground tunnels, elevator rooms, etc.

4. It can be used in combination with various waterproof membranes or waterproof coatings to improve the waterproof effect and durability.

Application Guidance

1. The base surface is required to be flat, clean, free from sand, loose, and the moisture content is less than 8%.

2. During construction, the base surface should be checked first to ensure that it meets the requirements, and a layer of primer must be applied first, and the primer must be uniform.

3. After the primer is cured, the second brushing is carried out. The brushing direction must be perpendicular to the previous one to prevent from leakage and scraping. Brush three to five times in turn.

4. After the completion, before the waterproof layer is cured, no access to people or the next process is allowed, so as not to damage the waterproof layer.
