Self smoothing water dispersible epoxy overlay system for concrete floors
Description
MASTERTOP 1730 is a multi-component, self smoothing, water dispersible epoxy overlay system, designed to provide continuous protection for concrete floors in light, medium and heavy duty applications at thicknesses of between 2 and 4mm or greater. The system can be applied successfully at greater thicknesses, but your BASF representative should be consulted first.
The product has been successfully applied to terrazzo tiles, and timber with certain modifications to the sealer system and substrate support. For applications other than to concrete, please contact your BASF representative.
Primary uses
MASTERTOP 1730 has excellent wear and abrasion resistance for floors subjected to high volume traffic in warehouses or workshops.
The smooth, dense, matt finish is ideal for situations requiring a hygienic, easily cleaned surface. MASTERTOP 1730 has good wear and abrasion resistance and is suitable for use in many industrial applications as a topping. It is especially suitable in food, beverage, and wet process industries.
The product offers good general resistance to a broad spectrum of chemicals, but as in all cases of chemical exposure a full analysis of operating conditions is required, followed by reference to chemical resistance data, to ensure product suitability.
MASTERTOP 1730 is used extensively in the following industries:
- Food & beverage production - including dairies, bakeries and confectioneries.
- Pharmaceutical, medical or laboratory situations.
- Engineering - including car production and aircraft maintenance units.
- showrooms, demonstration areas.
- Industrial and commercial kitchens.
- High stack warehouses.
- Wet process industries

Guide to application
Surface preparation:
The preferred method for surface preparation of concrete is captive blasting, which gives a well prepared laitance free, vacuum cleaned surface with a roughened finish.
Other suitable methods are surface scarifying using mechanical scarifiers such as Errut or Von Arx, high pressure water jetting or sand/grit blasting.
Damaged or deeply pitted areas can be repaired and levelled using MASTERTOP 1730 filled out, if required, with additional aggregate.
Sealing:
It is essential to seal the concrete surface prior to the application of MASTERTOP 1730, to prevent air from the substrate rising through the MASTERTOP 1730 while it cures.
Prior to the application of the sealer coat the concrete can be soaked with clean potable water to reduce the danger of pinholes.
Seal the concrete with MASTERTOP 1700 resin.
Pour the base into the reactor component then using a slow speed drill and paddle, mix the components for a minimum of 1 minute, or until a uniform colour is achieved.
MASTERTOP 1700 can be applied to a damp substrate, but all standing water must be removed prior to application.
Apply the mixed sealer to the prepared dust free surface with a medium pile roller, at the rate of 5-7m² per litre depending on the surface profile of the concrete.
If the concrete is very absorbent, a single application may not be sufficient and a second coat may be required to ensure the surface is completely sealed. Allow the sealer to become tack-free before applying the MASTERTOP 1730.
Mixing:
Add the base and colour pack to the reactor then using a suitable drill and paddle, mix the two components together for a minimum of 1 minute, or until all striations have disappeared. Pour the mixed material into a suitable container of not less than 25 litres capacity then with the mixer running, slowly add the 1730 aggregate and mix for 2 minutes or until the mixture is smooth and free of lumps.
Always keep the mixing time the same for all batches, to ensure a uniform colour when the product is applied.
Laying:
Pour the mixed material onto the tack free sealed surface, and spread to the required thickness using a pin screed, notched trowel or steel float. As soon as the material has been spread to level, the applied material should be rolled with a spiked roller to release entrapped air and remove trowel marks.
Rolling should be continued until all air is released and a uniform colour is obtained.
The operator should always wear spiked shoes when using the spiked roller so that he can walk in the wet material.
Rolling should cease before the MASTERTOP 1730 begins to gel.
Maintenance
To keep the floor in pristine condition it should be treated with 2 or 3 coats of an acrylic emulsion polish prior to being put in service.
