POLYURETHANE WATERPROOFER FOR FLAT ROOFS DOES NOT REQUIRE REINFORCING FIBERGLASS MESH
Seals minor cracks of the substrate and ‘prevents’ their reappearance. Resistant to standing water and frost. Does not require reinforcing with fiberglass mesh. Properties Brushable elastomeric waterproofer based on polyurethane and acrylic water resins. It creates a seamless membrane without joints, with excellent adhesion to substrate. Certified by the University of Athens (Department of Physics, Division of Applied Physics), as ‘Cool’ material of low thermal conductivity and high reflectivity in the visible spectrum at a rate of 93%. It reduces the energy related costs for heating and cooling and significantly improves the energy efficiency of buildings. During the summer months it reduces the interior temperatures of the spaces below the roof surface. During the winter months it presents zero water absorption and maintains the roof surface dry. Classified as product for surface protection of concrete surfaces per EN 1504-2. Applications HYDROSTOP-PU is suitable for waterproofing roofs, terraces, parapet walls, gutters, drywalls and cement boards, as well as for properly installed and well adhered asphaltic roofing roll. Advantages
It is not affected by UV radiation (chalking). UV Resists the corrosive gases in the atmosphere as well as chlorides, carbon dioxide and sulfur oxides. Excellent resistance to the creation of mold and algae. mold Use 1. Preparation of new surfaces: Using a roofing scraper or a wide chisel, remove all deteriorated sections, if any. Continue by using a hard, street type, broom. If any moss, lichen or grease stains are present, remove them by using D-95 CLEANER of DUROSTICK or a bleach-water solution at a dilution ratio of 1:1. Scrub the surface thoroughly and rinse with plenty of clean water. Surfaces to be waterproofed must be dry and should not get wet for the next 48 hours, in order to avoid surface moisture from being trapped. 2. Preparation of surfaces coated with waterproofing product(s): • Detached torch-down roofing materials: Remove them using a wide roofing scraper or roofing torch. • Well adhered existing torch-down roofing materials, it is required to thoroughly remove all the dust from their surface and to seal any detached sections (if needed). • Detached or deteriorated elastomeric waterproofers, have to be removed using a wide roofing scraper or a razor blade. • Detached elastomeric materials that are not visible, can be found using a garden
High reflectivity of solar radiation, due to its exceptional whiteness. Excellent water vapour permeable. Its flexibility remains unaffected, even at -25°C. hose. Pour water on the roof surface from about 1 meter high and listen carefully. Notice the change of the sound the water makes when it hits the detached sections of the waterproofing and mark them. Cut the detached sections using a razor blade, a scraper or other mechanical means. Scrape the defective material off. 3. Application: Before application on cement surfaces, using a roller and a brush, prime the surface using the water soluble, micromolar stabilizer AQUAFIX or the SOLVENT BASED PRIMER diluted 50% with THINNER 101 of DUROSTICK. Alternatively, dilute the product by adding 30% water and prime the entire surface. Once the primer has been absorbed into the surface and is completely dry, it is possible for some hairline cracks to become visible. Treat those cracks by applying several coats of HYDROSTOP-PU, until they are completely sealed. Seal wider cracks (≥ 1mm) using the elastomeric sealant DS POLYMER or by using the polyurethane elastomeric sealant DUROFLEX-PU of DUROSTICK. Once the sealant is dry, apply 2 coats of the polyurethane waterproofer HYDROSTOP-PU over the sealed cracks.

Offers walkability in short time without sticking. Its super white color is unaffected by mudrain (does not yellow), thanks to its unique water repellency. USEFUL TIP In addition to the roof/terrace surface, protect also the wall surfaces of your house with the elastomeric and sealing paint D-80 HYDROSTOP ELASTIC. It covers hairline and capillary cracks and is particularly resistant to sudden temperature variations, intense sunshine, constant humidity and frost. Maintains its color stability over time process by coating the entire area with 2-3 crosswise coats, to cover any minor substrate imperfections. Apply each coat 6-18 hours after the previous one was applied (depending on ambient conditions) or once the previous coat has completely cured and it is walkable.
HELPFUL TIPS - NOTES • Mix well before use. • Waterproof all vertical surfaces around the roof (parapet walls), their entire height. • Avoid exceeding thicknesses of 0.5mm per coat. • Low ambient temperatures delay the final curing time while high ambient temperatures speed up the curing process. • Avoid applying the product in high humidity conditions or when there is possibility of rain within the next 24 hours.
