Waterproof flat ROOFS and ROOF TERRACES with 0% slope (where ponding occurs or stagnating water may accumulate)
ARCATHANE ROOF WATERPROOFING is a high quality colored and decorative liquid-applied, water based, modified polyurethane membrane used for long-lasting waterproofing of flat roofs and terraces with substandard slope.
Used to provide a long-lasting waterproof membrane on roofs and terraces with 0% slope, ARCATHANE is a liquid, elastic modified polyurethane membrane based on innovative technology - long-chain polyurethane macromolecules are incorporated in a water medium forming stable dispersions.
ARCATHANE offers the highest level properties of solvent based products in an ecological, consumer and evironmentally friendly, water-based, low VOC, no ADR transport product.
Even if the membrane gets damaged, it can be easily repaired locally.
Arcathane Waterproof coating for flat rooftop, terrace, balcony, deck Advantages:
- Light foot traffic resistant (to get an heavy foot traffic resistant apply an additional coat with Arcathane Traffic)
- One component, easy to apply (roller or airless spray)
- Even if the membrane gets damaged, it can be easily repaired
- Waterproofs all concrete,cement fibre cement, asbestos cement, masonry an plaster surfaces
- Interior/Exterior - waterproof all flat surfaces (standard minimum slope not required)
- Water vapour permeable
- Water Based (no solvent)
- Resistant to freeze-thaw cycles
- Maintains it mechanical properties in temperature conditions from -15°C to + 70°C
- Renders a seamless 100% waterproof cover
- Durable and resistant to water stagnating
- Excellent adhesion to almost any type of surface with no additional fixation or mechanical fasteners
- Forms a seamless membrane that adapts to any form
- Resistant to detergents, oils, seawater and domestic chemicals
- Over 20 years of positive feedback worldwide
Principal uses of Arcathane waterproof coating for flat surface:
It can be used for new balcony/terrace construction but also for repair or renewal.
Arcathane if used alone is not suitable for foot traffic. If you need to walk on the surface on a regular basis,
you will add a protetion sealant (see Protection below).
Where to apply ?
Waterproofs all roofs and terraces with 0% slope and stagnant water.
- flat roofs and roof terraces
- balconies
- terraces
- veranda
- decks and wet areas (under tiles)
Which materials are concerned ?
- Concrete screed, slabs,
- cement boards,
- stones,
- bricks,
- breeze blocks,
- wood and plywood decks
- ceramic tiles,
- aluminium coated bitumen
- polyrethane foam insulation
Excellent adhesion to almost any type of surface with no additional fixation or mechanical fasteners.
The Arcathane waterproof system can be used as color decorative self finished systems but can also be covered with tiles, paving or timber decking (you will need to use Arcamesh in the first undiluted coat)
Arcathane is the roof repair paint that will seal quickly leaks in all major materials:
The surface can have no slope with Arcathane.
If you have a sloped surface you can use other waterproof coating:
For no foot traffic in order to waterproof per exemple a sloped roof you could use: Arcaroof (waterproof coating for sloped surface no foot traffic)
If you have a slope but you need foot traffic resistant product (walkable terrace, balcony with furnitures on) then use: Arcadeck (waterproof coating for sloped surface heavy foot traffic resistant)

TOOLS
Apply with a roller, paint brush, or airless spray gun.
Application Conditions:
Do not apply in temperatures <5°C or >80°C, if wind, rain, freezing.
Surface Preparation:
Optimum performance is achieved by using the right combination of products, surface preparation and application procedures.
- Careful attention to the preparation of the surface is essential: Surfaces to be coated must be dry, clean, sound and free of all contaminants, loose particles, dirt and dust.
- The humidity of the substrate must not exceed 5% Scrape and brush off all moss.
- The surface must be disinfected with a fungicidal product such as ARCAMOSS.
- Wait 24 to 48 hours before applying ARCATHANE to a treated surface.
- New concrete surfaces must have been left to dry at least 28 days before applying the ARCATHANE.
IMPORTANT : Do not apply if the moisture content of the surface is higher than 5%. You can measure with a moisture tester device.
Application:
Arcathane requires to be applied on the whole surface of the terrace or roof and also on the edges surrounding the surface up to 10 cm. It is not possible to treat partially. If you apply partially, water will seep under the treated part from the non treated part and make the resin blister or come off. In that case, the waterproofing will not be efficient.
First you will apply polyurethane mastic on all edges and small cracks (less than 2 mm non active cracks).
Application on flat smooth surface requiring no reinforcement mesh (no crack, no tiled surface):
- Primer: product itself diluted with 5 to 10% water. This % will depend on the porosity of your surface. Apply on the whole surface.
Let dry 24 hours before to apply the 1st coat - 1st coat: Apply a coat of undiluted product (as you would a paint but leave a heavier coat).
- Let dry 24 to 36 hours.
- 2nd coat: Apply a coat of undiluted product Let dry 24 to 36 hours.
Application over repaired joints, micro-cracks , weak spots or tiled surface requiring the use of the reinforcement mesh:
If you apply on tiles or concrete surfaces with micro cracks (less than 2 mm) you will embed a reinforced mesh ARCAMESH on the WHOLE surface.
On repaired joints, localized small cracks or weak spots such , internal angles, chimney flashings etc. you will embed a reinforced mesh ARCAMESH only on these localized parts if the rest of the surface is in a good condition.
Small cracks under 1.5mm can be treated before applying Arcathane with a polyurethane mastic.
- Primer: product itself dilute with 5 to 10% water. This % will depend on the porosity of your surface. Apply on all surface. Let dry 24 hours before to apply the 1st coat
- 1st coat: Apply the 1st coat ARCATHANE, immediately embed the ARCAMESH (pressing the mesh firmly into the wet coat smoothing out any air bubbles with a dry roller or trowel) then reapply directly a coat (undiluted) to saturate the surface «wet on wet».
Let dry 24 to 36 hours. - 2nd coat: Apply a coat of undiluted product (as you would a paint). Let it dry 24 to 36 hours.
Optionally to get more resistance you can add a 3rd coat.
Protection
Arcathan is flexible and soft. If you need to walk on Arcathane you will need to apply one or two coats of a protective product.
For light or regular foot traffic: ARCATHANE TRAFFIC : 1 or 2 coats of 200g each will protect Arcathan and allow foot traffic.
For heavy foot traffic or public places: ARCACLEAR TRAFFIC : 1 or 2 coats of 200g depending on the intensity of traffic
If you need to get a light antislip surface you can add 30 g corundum for 200 g of Arcaclear Traffic in the second coat of Arcaclear Traffic.
