ARCATHANE - Waterproof flat roofs and terraces

Please read carefully the method of application below.

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.

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.

1. 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
2. 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.
3. 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.

Drying Time:

Dry to the touch (at 20°C): 6 hours
Recoatable: 24 hours minimum.
Curing time: 7 days

Clean up:

With water immediately after use

Can be stored unopened in dry and cool place for up to 9 months.
Protect the material against moisture and direct sunlight.

Storage temperature: 5-30oC. Products should remain in their original, unopened containers, bearing the manufacturers name, product designation, batch number and application precaution labels.
