In this blog post, we will delve into the advantages of using Prokol MonoSeal for liquid waterproofing on flat roofs in Devon and the south west.

The Benefits of Prokol MonoSeal Liquid Waterproofing

  1. Superior Flexibility: 1500 Elongation for Constant Thermal & Joint Movement

Devon experiences a wide range of temperatures throughout the year, with constant thermal and joint movements being a common occurrence. Prokol MonoSeal is specially formulated to withstand these challenges, offering an elongation of 1500%. 

This exceptional flexibility ensures that the coating can accommodate thermal expansions and contractions without cracking or compromising the waterproofing integrity of the roof.

2. Wide Operational Temperatures – Ranging from: +120 degrees C to – 40 degrees C Up to 250 degrees C to – 50 degrees C

Another noteworthy feature of Prokol MonoSeal is its impressive operational temperature range. 

From scorching summers to freezing winters, Devon experiences extreme temperature variations. This waterproofing coating can endure temperatures as high as +100°C and as low as – 40°C, ensuring optimal performance and longevity under any weather condition.

3. Fully Moisture Tolerant

Moisture intrusion is a common challenge for flat roofs, especially in regions like Devon with frequent rainfall. Prokol MonoSeal has been specifically designed to be fully moisture tolerant. This means that it can be applied to damp or wet surfaces without compromising its effectiveness when used as a repair system to stop water ingress, by allowing for direct application on moist substrates, Prokol MonoSeal simplifies the waterproofing process and saves valuable time during roof repairs or installations.

4. Complete Hydrophobic Protection

A key requirement for any waterproofing system is to repel water effectively. Prokol MonoSeal excels in this aspect, as it offers complete hydrophobic protection. The coating forms a seamless and impermeable barrier, preventing water from penetrating the roof surface. 

By eliminating the risk of water ingress, Prokol MonoSeal ensures a dry and leak-free environment for the structure beneath.

5. Chemical Resistance for Enhanced Durability

In addition to weather challenges, flat roofs in Devon may also face exposure to various chemicals, such as pollutants or cleaning agents. 

Prokol MonoSeal has extreme chemical resistant properties making it an ideal choice for such scenarios. It provides enhanced durability and protection against chemical corrosion, ensuring that the waterproofing system remains intact and reliable even in harsh environments.

6. Smooth Finish for Aesthetically Pleasing Results

Prokol MonoSeal not only provides excellent functionality but also offers aesthetic benefits. 

The coating dries to a smooth finish, enhancing the visual appeal of the flat roof. Whether the roof is visible or not, a smooth and consistent appearance adds value and professionalism to any structure.

7. Reinforcement Layer – Free Application

Unlike some traditional waterproofing systems that require reinforcement layers, the laws of physics will tell you anything that heats with expand and when cooling it will contract. So, a flat roof will have an accumulative heat buildup that can reach in excess of 80 degrees C depending on the building materials used. Therefore, reinforcement cannot physically work. What is required is high elongation with the ability to deal with thermal expansion and contraction, i.e. free elastomeric properties. Prokol MonoSeal has all of the above properties in order to deal with thermal issues. By eliminating the need for additional materials this saves both time and both giving added assurance of a fit for purpose product.

8. Rapid Curing Time: from 20 seconds to 1 Hour depending what system is specified

Time is of the essence when it comes to roof repairs or installations. Prokol MonoSeal excels in this aspect as well, offering a rapid curing time of just one hour. 

This allows for faster project completion and minimizes disruptions to the building occupants.
