DR.S.BOND NON METALLIC FLOOR HARDNER provide a highly abrasion resistant surface to concrete floors by the dry shake-on method which ensures that the hardwearing surface bonds monolithically to the base concrete. They are ideally suited for all industrial areas subject to the heaviest traffic, e.g. loading bays, trucking lanes, car parks, workshops, machine shops, ramps and spillways.


Non-metallic floor hardner - does not rust or stain
Provides a hard, abrasion resistant surface
Forms monolithic bond with base concrete
Easy and economical to apply

Description non-metallic is quality controlled, factory blended powder which are ready to use on site. They contain special hardwearing aggregates which have been selected for abrasion and wear resistant properties as well as shape and size. These latter considerations, together with the use of high performance workability admixtures, produces a material which is easy to trowel into the surface of fresh, wet concrete. cure monolithically to provide a dense, non-porous surface which is extremely hardwearing and abrasion resistant. Monolithic cure ensures that problems normally associated with thin 'granolithic' screeds, viz., shrinkage, cracking, etc., are completely overcome. Being non-metallic, provide a non-slip surface which will never rust and disintegrate.

Technical Support offers a technical service to specifiers, end users and contractors, as well as on-site technical assistance in locations all over the country.


Abrasion resistance (IS : 1237-1980) has been tested as per IS:1237 - 1980 against control concrete for abrasion resistance. Test results showed that improves the abrasion resistance of concrete by 225% when tested as per guidelines in IS: 1237 - 1980. is applied in two stages

(a) The first application is made using 50% to 70% of the total material. is evenly broadcast onto the concrete surface. When the material becomes uniformly dark by the absorption of moisture from the concrete this first application can be floated. Wooden floats or, on large areas, the power trowel with disc may be used. It is important, however, that the surface is not over worked.

(b) Immediately after floating, the remaining. is sprinkled evenly over the surface. Again moisture is absorbed and the surface can be floated in the same way as before. Final finishing of the floor using a power trowel can be carried out when the floor has stiffened suffi ciently so that damage will not be caused.

Timing of Application

The timing of application is important and critical. If applied too early, bleed or excess water will wash away the cementitious content of the products, thereby making them ineffective. Also denser aggregates sink into the concrete. If the application of is done too late, there will not be sufficient water/moisture to absorb the material into the concrete. Material forcibly applied and trowelled thus, will cause cracks on the surface later, as there is no water/moisture to hydrate the product

Bay Edges

While applying at the edges of the concrete floor or, at the end of bays, extra precaution should be taken by way of sprinkling more material and finishing it smoothly with a steel trowel. This is an additional protection particularly to bay edges where the reaction due to heavy impact is more.

Packing is supplied in 50 kg HDPE bags.


If kept in original undamaged packing, the shelf life of should be atleast 12 months under normal warehouse conditions.


Health & Safety instructions contains portland cement and are therefore alkaline when in contact with water. Prolonged contact with the skin should be avoided. Any eye contamination should be washed immediately with plenty of clean water and medical advice sought.

Fire is not flammable.

Specification Clause

Non-Metallic surface floor hardener
All concrete floors shall be surfaced or broadcast with non metallic Standard, a non-metallic monolithic surface floor hardening compounds containing rust free, hardwearing aggregates. The aggregates shall have a Moh's hardness of not less than 8 for non metallic Standard.

Compressive strength metallic floor shall possess a minimum compressive strength of 50N/mm2 .

Application instructions

Base concrete
The base concrete should have a minimum cement content of 300 kg/m3. The concrete mix should be designed to minimise segregation and bleeding. Free water cement ratios of less than 0.55 are required. The concrete should have a slump of between 50 and 75mm. Use of water reducing admixture is recommended. The base concrete should be laid and compacted in accordance with good concrete practice. Accurate finished profile and minimum laitance build-up should be ensured. Particular attention should be paid to bay edges and corners to ensure full compaction. NON-METALLIC FLOOR HARDNER are applied for different types of industrial us

Thickness of topping Duty NON METALLIC FLOOR HARDNER required per 100 sq. mtrs of floors
½" (12/13 mm) Heavy 250 Kgs Approx. (Say 5 Bags)
½" (12/13 mm) Light 190 Kgs Approx. (Say 4 Bags)
¾" (18/19 mm) Heavy 350 Kgs Approx. (Say 7 Bags)
¾" (18/19 mm) Light 280 Kgs Approx. (Say 5.2 Bags)

It is recommended that the floor be marked off into bays of known area. Sufficient material should then be laid out to meet the required spread rates. Application of non-metallic floor hardner can begin when the base concrete has stiffened to the point when light foot traffic leaves an imprint of about 3mm. Any bleed water should by now have evaporated.


Tests have shown that proper curing of concrete floors treated with products such as non-metallic floor hardner is essential to ensure the physical properties of the floor. However, in indoor applications where curing conditions are less arduous and breakdown of the membrane slower, alternative approved methods of curing such as polythene sheeting or water ponding are acceptable.

Ready to use

Non-Metallic floor hardner is supplied ready to use on site. Cement or aggregates should never be added to Dr.S.Bond metallic floor hardener.

Coloured Floors

When a coloured floor is required, it is strongly recommended that a job site trial area is laid.

Surface Treatments

Penetration type surface treatments are recommended to give low porosity and dust proof property.
