Can Waterproof Coatings Expire? What You Need to Know
Waterproof coatings are indispensable materials in the home renovation and construction industries. Their stability and durability are critical for ensuring a building’s waterproof performance. However, many people overlook an important question when using these coatings: Can waterproof coatings expire and lose effectiveness? This article will explore the shelf life of waterproof coatings, the changes that […]
Compare APP and SBS modified bitumen membranes performance
APP (Atactic Polypropylene) modified bitumen membranes are plastomeric, offering superior high-temperature stability and UV resistance, while SBS (Styrene-Butadiene-Styrene) membranes are elastomeric, providing greater flexibility and low-temperature performance. Performance Comparison Aspect APP Membranes SBS Membranes Flexibility/Elasticity Less flexible, especially in cold; limited elongation below freezing. High elasticity and crack-bridging; excels in cold climates down to -25°C. […]
When Heat-Applied Bitumen Membranes Are Preferable to Cold Adhesive or Hot Mopping
In modern roofing and waterproofing work, bitumen membranes can be installed using several methods—most commonly heat-applied systems, cold-applied adhesives, and traditional hot-mop asphalt. Each method has its strengths, but there are clear situations where a heat-applied membrane offers distinct advantages. This article explains when the heat-applied approach is the most suitable choice and why it […]
SBS/APP Modified Bitumen Waterproof Membranes: A Comprehensive Guide
SBS and APP modified bitumen membranes are high-performance waterproofing solutions widely used in roofing and below-grade applications. Known for their durability and versatility, these membranes provide reliable protection in a wide range of climates. They come in two primary types—SBS (Styrene-Butadiene-Styrene) and APP (Atactic Polypropylene)—each offering unique benefits based on project requirements. What Are SBS […]
Sunlight Resistance of Oil-Based Polyurethane Waterproofing Coatings
Oil-based polyurethane waterproofing coatings, a widely used material in building waterproofing, have attracted considerable attention for their performance. Whether oil-based polyurethane waterproofing coatings are sun-resistant has become a core concern for many users. Combining material properties, actual application cases, and industry research, the following analysis provides a multi-faceted analysis: I. Weathering Resistance of Oil-Based Polyurethane […]
Choosing the Right Root Barrier for Green Roof Waterproofing Protection
Green roofs have become increasingly popular for their ecological and architectural benefits. Within their layered construction, the waterproof membrane plays a critical role in protecting the building structure from moisture damage. Directly above this membrane lies another essential component—the root barrier layer. Its purpose is to prevent plant roots from penetrating and damaging the waterproofing […]
Installation Process of SBS & APP Waterproofing Membranes
Waterproofing is critical for extending the lifespan of building structures, especially roofs. Contractors widely use SBS (Styrene-Butadiene-Styrene) and APP (Atactic Polypropylene) membranes for waterproofing projects. This guide details the installation process to ensure optimal water damage protection. 1. Installation Process Overview Clean the substrate Apply primer Install reinforcement layers (if required) Lay the membrane Seal […]
TPO vs PVC Waterproofing: Pros, Cons & How to Choose
When selecting a single-ply membrane for a flat or low-slope roof, TPO and PVC are the two most common choices. Both systems deliver reliable waterproofing, but they differ in chemistry, performance, cost, and ideal use cases. This guide provides a streamlined comparison to help you make an informed decision.
