Advantages Of Polyurethane Waterproofing Treatment

Are you looking for polyurethane waterproofing treatment at your home? You have recently come across this term but still wondering what it means? This post will bring an end to all your confusion and offer you a vast array of advantages of using the polyurethane waterproofing membrane. 

All about polyurethane

Polyurethane consists of two main components- the base and the reactor. Polyol acts as the base and isocyanide as the reactor. If you mix both the substances in a specific ratio, you get a liquid coating used in waterproofing treatments. 

The ease of installation of the polyurethane waterproofing membrane makes it a popular choice of waterproofing applications. Unlike other waterproofing treatments like liquid applied membrane and sheet membrane, polyurethane treatment requires less supervision and skill. The process of application is fast, and you can also use this treatment in the post-construction form.

The product supplier often ends up prescribing you the application and the surface preparation method. You can also expect continuous supervision by them throughout the project period. Polyurethane waterproofing treatment comes with a vast array of benefits. Read on to know more.

Check out the advantages

• Polyurethane membranes come with the most exceptional level of elasticity.
• The thickness required for applying the coat is just 2mm. 
• It forms a seamless continuous coat on the surface of the application.
• You can apply it to any surface.
• You can try applying the membrane on a lightweight structure as the weight of the material is minimal after cutting. 
• It can keep UV radiation at bay effectively. Moreover, it can also save any external adverse effects at bay.
• Possibility of DIY applications is high.
• The material comes with a service life of near about 25 to 50 years.
• Restoration of the membrane is comparatively easy and economical as the total deletion of the material is not needed.
• You can apply polyurethane coating on an existing waterproofing system too.

Know the process

• To start with the waterproofing process using a polyurethane waterproofing membrane, you need to clean the roof surface thoroughly and remove any foreign matter if present.
• Any cracks on the surface preparation area need to be cut out to the V section, properly cleaned and filled with 2-part white cement and 1-part crack filling compound. 
• You should neutralize the surface by removing alkalinity through an acid application.
• To apply the initial coat, you need two-pack polyurethane primers. It acts as a grip coat, which should be allowed to dry for 8 hours.
• You should then apply three following coats allowing 12 hours in between the layers. Two-components of polyurethane are mixed according to ratio. 
• The PU coating should continue 150mm over the walls. You should also continue it till 100mm into the rainwater drain.
• The final coat should be sprinkled with 300 microns of the sand layer.

The advantages of using the polyurethane waterproofing membrane have surely convinced you to try this waterproofing method. However, at the initial planning stage, you should consult with a specialist to avoid any fatal problem in the future.
