Construction Steps for Rooftop Waterproofing with Polyaspartic Polyurea

Description

Roof waterproofing is a vital aspect of building protection. Being constantly exposed to the elements, such as wind, sun, and fluctuating temperatures, without proper waterproofing, roof cracks and leaks can pose a threat to housing safety and affect the lifespan of a building.

 

Polyaspartic polyurea is an ideal new eco-friendly material for rooftop waterproofing. Known for its "skin-like" waterproofing ability, it's favored for its exceptional weatherability, aesthetic appeal, and elasticity to resist cracking. To fully harness the benefits of this outstanding material, certain key points in the construction process must be meticulously followed.

 

Construction Steps for Polyaspartic Polyurea Rooftop Waterproofing

  1. Surface Preparation

Smoothen any uneven areas on the surface and walls. Before applying the waterproof layer, ensure the base is level, clean, and free of debris or standing water. After cleaning the surface, apply a sealing primer to strengthen the base and lock out moisture.

  1. Crack Repair

Remove and clean the pre-existing cracks, old expansion joint materials, and any peeling or detached coatings on the rooftop. Seal the gaps (with a sealing primer), and then inject polyurea elastic joint filler to level the cracks. For effective waterproofing of gaps, use a "one fabric, two coatings" process: first, apply a layer of polyurea waterproof base coat, lay a polyester fabric (recommended width: 15-20cm) ensuring it is flat and void-free, and then apply another layer of polyurea waterproof base coat to fully cover the fabric.

  1. Vent Hole Creation

Create vent holes and set up vent pipes, securing the base with polyurea elastic material. The purpose of vent holes is to eliminate water and moisture trapped within layers to prevent issues like weak adhesion and blistering of the waterproof layer.

  1. Sealing Drainage Points
    Often overlooked in rooftop waterproofing, improper treatment of drainage points can lead to water seeping in from the sides, causing local leaks. Ensure the polyurea waterproof coating extends about 5cm into the inner wall of the drainage points, achieving seamless integration between the pipe wall and the waterproof coating.
