Bond HG

Bond HG is a multipurpose, multifunctional, reactive product; its addition to plaster, mortars and conglomerates in general, both based on cement and bonded with lime, provides a complex and efficient physical/chemical action. The polymers and the reactive fillers increase stickiness, adhesion, watertightness, and deformation capacity, and reduce the alkali content of free products from the reaction of cement hydration for an amount of about 1000 mg per kg of Bond HG introduced into the mixture. The superpozzolanic reactivity, activated by the distinctive features of the filler, causes significant increases in chemical resistance, weatherability, stability and overall durability.

The high pozzolanic reactivity (metakaolin) Bond HG fillers react with the free lime [Ca(OH) ₂] produced by the hydration reaction of portland cement. The free lime is thus converted into more stable calcium aluminates and calcium silicate. The reaction between [Ca(OH)₂] and metakaolin is endothermic, it thus develops less heat in the system, allowing a more balanced hardening of hydraulic binders (cement or lime).

Fields of application

Preparation of adhesive, deformable, high-protective performance and waterproofing mortars and plasters for civil, industrial and hydraulic engineering, in urban, marine, and mountain environments. Repairs and restorations of floorings, road circuits and rural roads. Non-structural construction joints, sealing, restorations, and reconstructions. Particularly suitable for providing adequate cohesion and deformability of shotcrete lining of floor heating systems. Pure, or diluted in water up to a dilution ratio of 1: 2, it is an excellent adhesion primer for porous, weak or chalking substrates, to be applied immediately before the covering layers (mortars, grouts and concretes).

Allowed supports

Mode of use

Remix Bond HG thoroughly in the bucket, and dilute it with water as required. Add the prepared solution to the cement (or lime) and aggregates mixture, in the most suitable dosages for this application.
It is always essential to carry out preliminary tests for an accurate definition of the mixtures to use, and to check the suitability of the product on the basis of the specific requirements.

Indicative dosages

	Cement	Water	Bond HG	Sand	Yield
Construction-grade grout	50	16	16	-	50
Bonding roughcast	50	15	8	50	57
Plasters	50	20	8	150	105
Thin coatings	50	20	8	100	85
Screeds	50	25	4	150	105
Concrete	50	25	2,5 - 3	250	150
As primer for absorbent materials	---	1,0	1,0	---	1,9

The indicative dosages refer to the unit of measurement represented by two 25 kg bags of binder (cement or lime); the right column shows the indicative yield in litres of fresh mixture. By way of example, we just have to multiply by 2 times the dosages of the plaster column, to get the doses for a 200 litre concrete mixer.
