EASY BOND for Permanent Formwork

Technical Brochure

EASY BOND for Permanent Formwork- is ONE-COMPONENT BOND FLEXIBLE COATING

DESCRIPTION:

EASY BOND is a one-component cement-based mortar. Once mixed only with water, it provides a high-performance flexible key coat bonding bridge for application to NON-POROUS substrates.

Use Easy Bond as:

A cementitious key coat bonding bridge on Permanent Formwork i.e. DINCEL, REDIWALL, and ZEGO. Non-porous surfaces such as (powder coated) metal, shipping containers or any other PVC-based walling system.
Provides an excellent base for the application of renders, paints, tiles and stonework.

ADVANTAGES

Provides a base coating suitable for substrates subject to

1. Thermal movement.
2. Environmentally friendly and suitable for application in poorly ventilated areas.
3. Acts as an anti-fracture membrane between the substrate and other finishing coats
4. Does not require a primer, scuffing or sandblasting. This saves labour costs.
5. Up to 15 years life expectancy (depending on the application area and usage)

APPLICATION INSTRUCTION

Surface Preparation

The surface to be coated must be. Sound, clean, and free of all traces of paint, dust, grease, efflorescence, loose particles, gypsum, plaster and mould release compounds. Holes, voids, honeycombs and cracks, once opened to a minimum of 2 cm in Drizoro Maxrest
Exposed steel bars must be cleaned and patched with Drizoro Maxrest (Technical Bulletin no. 4) with 1 cm. a minimum thickness.

If the steel bar is corroded, treat it with the oxide converter Drizoro Maxrest Passive (Technical Bulletin no.12). Thoroughly wash down and saturate the substrate with plenty of water. Remove all free-standing water before the application of Drizoro Maxrest.

Apply EASY BOND by Texture or foam roller or broom Spreading a homogeneous and continuous coating of 1 mm approximately.
Once applied. do not:- 1. overwork the surface.  2. do not apply to a painted surface.

Allow a drying time of a minimum of 3 days.

For large areas:-  EASY BOND can be sprayed. When sprayed, comb the fresh Coat with a broom to make sure that the whole surface is covered homogeneously.

On fissures, concrete joints, corners and cracks, once repaired, apply the first coat of EASY BOND at 1,0 Kg /m² and while it is still fresh, place Drizoro Maxmesh either 50 mm or 200 mm roll.

Mixing:

A 20 kg bag of EASY BOND requires 6 – 6.3 litres of water (20 ± 2 %), depending on application temperature and substrate conditions. Pour the required amount of water in a clean container, and slowly add EASY BOND mixing by a slow speed electric drill (400-600 rpm) fitted with a disc mixer for about 2-3 minutes until achieving a lump-free and homogeneous mix.

Allow the mixture to rest for 2 to 3 minutes to fully wet out all the powder, and then remix briefly before applying. To keep the workability of the fresh mortar, remix again briefly, but do not add more water. Do not mix product that cannot be applied within 20 – 30 minutes.

Curing

Curing time for putting into service is 3 days, at 20ºC and 50% R.H

Cleaning.

Clean all tools immediately after use with water. Removal, once cured, is by mechanical methods.

EasyBond PACKAGING

Supplied in 20 Kg bags, available in grey.

STORAGE

Twelve months in its original unopened packaging, in a dry and covered place protected from humidity, frost and direct sunlight, at temperatures above 5 ºC.

IMPORTANT CAUTIONS:

Do not add cement, admixtures, sand or any other compound.
In case of doubt related to the kind of water to be in contact with EASY BOND or other uses not specified in this Technical Bulletin, consult Technical Department.

CAUTION:

We do NOT recommend the use of EASY BOND over ZINC or ZINC coated surfaces, treat these surfaces using Drizoro Maxrest Passive as per TDS prior to coating.

SAFETY AND HEALTH

EASY BOND is an abrasive compound so protective rubber gloves and goggles must be used during application. In case of eye contact, rinse thoroughly with clean water, but do not rub. In case of skin contact, wash affected areas with soap and water. If irritation continues, seek medical attention.

Special Caution:

Applying a single heavy or large cladding ensures the correct adhesive is used.

Apply adhesive to the entire surface, do not spot apply.

Limit single weight to 20 Kg. If an item/m² exceeds this, also use fixing anchors.
