PROPERTIES

Flexible sealant, adhesive and grout sealer of two components. After curing, it forms a flexible durable membrane with minimal shrinkage, highly resistant to mechanical stresses and to alkaline environments. It bonds to surfaces powerfully. It prevents moisture or water penetration in the joints between similar and/or dissimilar materials, such as plaster with concrete, metal, clay roof tiles and stone, wood, etc. DUROFLEX POWDER ensures long-lasting protection as it seals, bonds and waterproofs perfectly.
It is ideal for preventing rising damp on exterior walls. Classified as product for surface protection of concrete surfaces (c) per EN 1504-2

APPLICATIONS

DUROFLEX POWDER is suitable for flexible seals and waterproofing in a huge variety of applications:
• As a sealant, in the perimeter of outdoor horizontal and vertical surfaces, at their junction.
• It seals the perimeter of a building at ground level preventing rising damp (pic.5) forming from the bouncing rain when coating 15cm to 30cm from the ground/floor level up.
• It waterproofs cement skirting on roofs, presenting cracks caused by micro-vibrations, sinking ground or unsuitable material used for the creation of the skirt.
• Points of contact of pitched roofs with side walls (pic.1,3), hips and lead lined valleys.
• Bonding of detached ridges and waterproofing of the cracked mortar with the same material.
•Sealing and flexible waterproofing of cracked roofing tiles, roofing ornaments and their bonding mortar.
• Sealing holes created on a surface during installation of boilers, air conditioners, solar water-heaters and photovoltaic systems.
• Sealing of areas of load bearing elements joining with walls made of brick or aircrete, thus preventing cracks and detachments.
• Sealing joints between plaster and stone (pic.4).
• Sealing the edges of marble saddles with plaster.
• It waterproofs skylight casements, roof windows and chimneys’ bases (pic.2).
• Flexible seal for drywall and cement board installations, preventing the usually created cracks for such construction practices.
• Flexible bonding of insulating boards and soundproofing materials on any surface wherever deemed necessary.

 

ADVANTAGES

• Lightly soak the application surfaces first to create appropriate bonding conditions on every porous mineral surface without need for priming.
• Does not favor bacteria and mold growth.
• Easily applied using a brush.
• Paintable when using elastomeric or acrylic paints.
• Durable in time.
• It does not crack.

USE

1. Surface preparation
The substrate must be free of dust and loose materials. The substrate should be soaked thoroughly. On (salvageable)deteriorated surfaces, first prime with the micromolar stabilizer, AQUAFIX of DUROSTICK.
2. Application
Empty the powder into the emulsion at a ratio: 1.75kg powder to 0.7lt emulsion. Mix with a low rpm electric drill until a lump free, homogeneous paste is formed. The mixture must be thick enough so it does not drip. Allow the mixture to mature for 5-10 minutes and mix periodically without the addition of water. The mixture remains workable for 2 hours and is applied with a brush in coats of 1 to 1.5mm each one. Apply the next coat within 2-3 hours, following the previous one, without the need for soaking. During the summer months, on exterior surfaces, soaking is recommended after 3-4 hours, at least once. At temperatures below + 5°C and above + 35°C, or if there is a chance of rain for the next 12 hours, the application have to be avoided.

CLEANING

Any residues should be removed immediately with a damp sponge. Clean all tools with water, immediately after use.

NOTES

•Before mixing the two components, stir the resin very well in its container.
•After curing, the product is harmless to health.

CONSUMPTION

1.0kg/m²/mm thick coat.

STORAGE


Store sealed containers in dry and shaded places of low humidity, for at least 12 months from production date.

SAFETY DIRECTIONS
