DEFIX PROSEAL PO-1 Roof Waterproofing Coating – Durable, highly elastic, and superior UV-resistant exposed waterproofing solution
Roofs, terraces, balconies, and flat roofs are areas that are constantly exposed to direct sunlight, heavy rain, UV rays, and daily temperature fluctuations. Over time, these factors cause concrete surfaces to develop hairline cracks, water leakage, peeling finishes, and reduced service life of the structure.
Many constructions have been waterproofed, but after only a few rainy seasons, water leaks, ceiling stains, mold, and rapid deterioration reappear. The cause lies not only in the construction technique but also in the selection of materials that are not suitable for outdoor working conditions.
That is also why more and more investors, contractors, and construction units prioritize the use of water-based polyurethane waterproofing products that can create seamless membranes, withstand UV rays, and maintain long-term elasticity.
DEFIX PROSEAL PO-1 – The new generation roof waterproofing coating
DEFIX PROSEAL PO-1 is a single-component water-based polyurethane waterproofing coating, developed to create a seamless waterproofing membrane on roof surfaces and exposed areas. After application, the product forms an effective water-blocking membrane while ensuring flexibility to accommodate substrate movement, helping to prevent cracking during use.
In addition to its waterproofing effectiveness, DEFIX PROSEAL PO-1 also possesses excellent resistance to harsh weather, UV rays, and mechanical stress, making it suitable for the hot, humid, and rainy climate of Vietnam.
Outstanding advantages of DEFIX PROSEAL PO-1
Superior waterproofing ability
The cured film forms a continuous, seamless surface, minimizing the risk of water permeating through gaps. This is a significant advantage compared to many traditional waterproofing methods.
Extremely high elasticity
One of the outstanding features of DEFIX PROSEAL PO-1 is its elongation at break of 600% or more. This helps the coating adapt to the expansion and contraction of concrete structures, preventing cracking due to temperature changes or minor structural vibrations.
UV and outdoor weather resistance
The product is designed to perform in exposed conditions, with good UV resistance, anti-aging properties, reduced chalking, and long-lasting protective effectiveness.
Ponding water resistance
Many areas such as terraces or flat roofs often have standing water after rain. DEFIX PROSEAL PO-1 can withstand ponding water without cracking or degrading the coating quality.
Walkable surface
After curing, the film can withstand normal mechanical impact, making it suitable for areas requiring foot traffic for maintenance or daily use.
Simple application
The product is a single-component water-based polyurethane, so no complex mixing is required. Applicators only need to stir it well before use and can apply it with a roller, brush, or spray gun, saving time and labor.
Applications of DEFIX PROSEAL PO-1
Thanks to its excellent adhesion to various materials, DEFIX PROSEAL PO-1 is widely used for:
-
Waterproofing concrete roofs.
-
Waterproofing terraces.
-
Waterproofing balconies, loggias.
-
Waterproofing flat roofs.
-
Waterproofing exterior walls.
-
Waterproofing bathrooms.
-
Waterproofing wet areas.
-
Waterproofing metal surfaces after using an appropriate primer.
-
Residential, commercial, and industrial projects.
-
New construction and renovation projects.
This flexibility allows the product to meet various practical construction needs.
Notable technical specifications
DEFIX PROSEAL PO-1 is available in 4 kg and 20 kg packaging, with a shelf life of up to 24 months when stored under proper conditions.
Some outstanding specifications include:
-
Density approximately 1.25 ± 0.05 kg/L.
-
Surface dry in approximately 3 hours.
-
Fully cured after approximately 24 hours.
-
Adhesion strength after 7 days is 0.80 MPa or more.
-
Elongation at break is over 600%.
-
Theoretical coverage rate approximately 0.3 – 0.5 kg/m²/coat.
These specifications demonstrate that the product meets the requirements for waterproofing, adhesion, and durability for exposed structures.
Correct application procedure
The effectiveness of waterproofing largely depends on proper surface preparation.
Before application, the surface must be clean of dust, grease, and other impurities. The surface must be dry, sound, and stable; corner areas should be carefully treated and reinforced with mesh if necessary.
Suitable application conditions include a surface temperature of 8°C to 35°C, substrate moisture content below 16%, and ambient humidity not exceeding 80%.
Before use, stir the product thoroughly for about 2–3 minutes with a mixer at 400–600 rpm.
Apply at least two coats:
-
The first coat should be diluted with approximately 5% water to act as a primer.
-
After approximately 24 hours, apply the second coat undiluted.
-
If reinforcement with fiberglass mesh is required, apply at least three coats according to technical instructions.
During application, avoid rain or conditions where rain is likely to ensure the quality of the waterproofing membrane.
