FEATURES

• High performance polymer additive for cement and concrete mixes.
• Water resistant - used as a temporary waterproofing barrier on rooftops .
• High strength - ideal for patching, can be feathered out to repair minimal cracks and also for use in coving areas .
• Non-toxic - does not create occupational health & safety concerns.

SURFACE PREPARATION

The surface to be treated should be clean, sound, free from oil, grease, laitance, dust and other barrier materials.

Use a suitable degreser to remove polish, wax, grease, oil and similar contamination substances prior to the mortar application. New concrete should be allowed to cure for at least 28 days.

MIXING

Temporary Waterproofing
1 part Polymer bonding agent : 2 parts cement, (by volume).

Admix for render / screed / coving: Mix 1 Part Polymer bonding agent with 3 parts water and use as the gauging mix (mixing water) with a 3 : 1 or 4 : 1 sand / cement mix.

Binder coat : 1 part E 135 : 1 part water : 4 parts cement (by volume).

APPLICATION

Temporary Waterproof
E 135 with fine cement to a lump free consistency. Pre - moisten the concrete then apply a first coat using a brush or roller to achieve 1mm wet bed thickness. Allow first coat to set, then apply second coat at right angles to the first application to ensure no pinholing occurs.

Slurry Coat
Mix to a thin binder and spread the mix overthe surface with brush or roller, or small broom. Maximum thickness recommended is 2 mm. While the binder coat is still wet, apply render or screed over it.

Render/Coving
Apply binder coat on the prepared surface. While the binder coat is wet apply the Polymer bonding agent mortar mix with a wood float trowel, ensuring firm pressure on the trowel to work the render into good contact with the surface.

Screed
A minimum thickness of 15mm is recommended when using diluted Polymer bonding agent instead of water. For a thickness greater than 40mm, reinforcing mesh is required.

Using a roller, brush or a flat trowel, coat the prepared area with a binder coat of Polymer bonding agent to improve adhesion to the substrate.

Apply the screed mix whilst the binder coat is still wet using a straight edge, trowel or timber batten to level the screed.

Achieve falls in shower recesses to a minimum 1 : 60 : internal wet areas (eg bathrooms) to a minimum of 1 : 80 : and external areas to a minimum of 1 : 100.
Screeds should be left with a wood float finish to create a key for tiling and waterproofing. When reinforcing the screed with mesh, apply first layer of screed, lay in the mesh and apply the second layer of the screed. Do not lay the mesh directly onto the substrate.

DRYING TIME

Approximately 16 hours (overnight) at 23ºC and 50% relative humidity when used for water resistant or render / screed.

PROPERTIES

STORAGE AND SHELF LIFE

E 135 has a shelf life of 12 months if kept in a dry, store between 5ºC and 30ºC in the original unopened containers. The product should be protected from frost, away from direct sunlight and sources of heat.

PRECAUTIONS

In case of contact with the eyes, rinse immediately with plenty of water and seek medical advice and after contact with the skin wash immediately with plenty of soap and water (do not use solvents). Prolonged contact with the skin should be avoided, especially where the user has an allergic reaction to epoxide materials. Always wear gloves and eye/face protection is necessary. Observe personal hygiene, particularly washing the hands after work has been completed or at any interruption whilst work is in progress. Care should be taken when removing gloves to avoid contaminating the insides. In case of accidents seek medical advice.

DISPOSAL / SPILLAGE

Spillage of any of the C 20 product should be removed with plenty of water. Disposal of such product or empty packaging should be in accordance with local waste disposal authority regulations.
