Description

Harmony Smooth Concrete is a self-levelling compound made up of cement, selected aggregates, resin and super-plasticizing agents.

It can be used for the rapid finishing of large surface areas, or where only limited shading effects are required.

Harmony Smooth Concrete can be applied from a minimum thickness of 4 mm up to a maximum thickness of 27 mm. It produces a smooth and silky finish, with subtle effects.

Tools & Cleaning

Mixer, Flemish trowel, gauge rake, studded boots, screen or spiked roller, 40-litre bucket, weighing balance, protective gloves, tarpaulin, adhesive tape. Clean tools in water after use.

Prepare the support

The base surface must be resistant, sound, solid, clean, dry and free of humidity.

Use Harmony neutral agent or Harmony degreaser for any cleaning required (to remove grease, oil etc).

Any existing expansion joints, bay joints and edge joints in screeds or slabs should be observed. Specifically, this is essential in the case of heated floors.

Should it be necessary to level the surface before the application of Harmony Smooth Concrete, use Harmony levelling compound.

Otherwise, you are advised to check the compatibility of levelling with our primers and with Harmony Smooth Concrete.

Regardless of the base surface, whether porous or impervious such as tiling or anhydrite screed, sand- screened Harmony epoxy primer should be applied. (For more information see data sheet epoxy primer).

Internal corners (pillars, right angles, etc.) should be rounded at the base in order to prevent cracking. Door threshold strips should be fitted to allow the interruption of the pouring process.

Do not forget to fit the edging strip, in order to separate walls from the flooring, and protect timber with adhesive tape.

It is essential that exposure to wind and sunlight should be prevented during application and drying. Close shutters or black out windows, and eliminate draughts by applying adhesive tape to the bottom of doors.

In case of application to a heated floor, floor heating should be shut down 48 hours beforehand. Floor heating may be restarted 72 hours after pouring.

Application

Application must be completed within a temperature range of 10° - 25°.

The mix will remain workable for 10 minutes.

For the application of Harmony Smooth Concrete, it is recommended to use a minimum of 3 persons (2 for the preparation of concrete mixtures and 1 for application), if not 4 persons (2 responsible for mixing and dosing, 1 for application and 1 for the acquisition of supplies).

Mix one 25 kg bag with 6 litres of water using a 500 r.p.m. electric mixer to produce a uniform mix by the progressive addition of dry powder to the water.

CAUTION: Harmony Smooth Concrete is sensitive to excess water. Always use the quantity of water recommended. The simplest solution is to weigh the water before each mixing operation.

Mix for a maximum of 3 minutes, then leave the mixture to rest for 1 minute in order to allow the dispersion of bubbles.

In order to eliminate any lumps, use the PermaPro screen to screen the mixture, then transfer to another bucket. Apply Harmony Smooth Concrete in a 4 mm layer using the PermaPro gauge rake.

If the PermaPro screen has not been used, the PermaPro spiked roller should be applied to ensure effective load distribution and the elimination of any lumps. Smooth the surface using the PermaPro Flemish trowel.

CAUTION: Excessive smoothing of the surface will create colour effects. In order to obtain the most uniform finish possible, and to prevent any joints between mixes, pouring operations should proceed in a rapid sequence, and the next bucket in succession should slightly overlap the previous bucket, in order to ensure a uniform surface.

The floor surface will be walkable, preferably in stockinged feet, 6 hours after the end of pouring at an ambient temperature 20°C (at standard humidity).

Depending upon the ambient temperature, 24 – 48 hours after the application of Harmony Smooth Concrete, it will be possible to grind the surface using an eccentric grinder with a 120-grit grade, or using a floor buffer.

Grinding produces a smoother and silkier finish, and enhances textural effects.

Protection

For normal traffic, use Harmony Béton Premium lacquer. For heavy traffic, or for maximum protection, use Harmony pore sealant, then apply Harmony Béton Optimum lacquer.

To protect your lacquer against abrasion, use Harmony Wax.

Teintes non respectées. Un seau de produit a provoqué une tache beaucoup plus foncée au milieu de la pièce. Le service technique ne comprend pas, c est tout. 50 €/ m2 pour un résultat désastreux. Pourtant la pose s est très bien déroulée, melanges chronomètrés et parfaitement dosés, temps de pose respecté. A éviter.

mise en oeuvre rapide. beau résultat. je l'ai ponçé même si cela n'est pas recommandé et le résultat est à mon gout au top. le ponçage réhausse beaucoup la couleur mais crée de superbe effet
