MASTERTOP 1230 PLUS 

Description

MASTERTOP 1230 PLUS is a multi component, self smoothing, solvent free, 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 glazed and terrazzo tiles, steel 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 1230 PLUS has excellent wear and abrasion resistance to floors subjected to high volume traffic in warehouses or workshops.

The smooth, ultra-dense and high gloss finish is ideal for situations requiring a hygienic, easily cleaned surface.

The product offers good general resistance to a broad spectrum of chemical corrosives, 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 1230 PLUS is used extensively in the following industries:

• Food production - including dairies, bakeries and confectioneries.
• Beverage production - including soft drink manufacturing.
• Pharmaceutical and other medical or laboratory situations.
• Engineering - including car production and aircraft maintenance units.
• Showrooms, demonstration areas.
• Industrial and commercial kitchens.
• High stack warehouses.

Advantages

• Excellent wear and abrasion resistance
• Easily applied
• Smooth high gloss finish for hygienic applications
• Good general chemical resistance
• Improves the working environment

Packaging

MASTERTOP 1230 PLUS is supplied as a 38kg multi component pack.

Hygiene

Taint tests carried out on MASTERTOP 1230 PLUS at the Leatherhead Food Research Association under artificially severe conditions showed that the risks of tainting foodstuffs are minimal during and after complete cure.

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.

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 1230 PLUS filled out, if required, with additional aggregate.

Sealing:

It is essential to seal the concrete surface prior to the application of MASTERTOP 1230 PLUS, to prevent air from the substrate rising through the MASTERTOP 1230 PLUS while it sets.

Seal the concrete with MASTERTOP 1200 PLUS resin diluted with 5% Solvent No. 2.

Pour the base and reactor components into a suitable mixing vessel, and add half a litre of Solvent No. 2. Using a slow speed drill and paddle, mix the components for a minimum of 1 minute, or until all striations have disappeared.

Apply the mixed sealer to the prepared dust free surface with a medium pile roller, at the rate of 5-8m² 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 1230 PLUS.

Mixing:

Pour the reactor base and colour pack components of the MASTERTOP 1230 PLUS into a suitable mixing vessel, with a capacity of not less than 25 ltrs. Using a suitable drill and paddle, mix the components together until a uniform colour is achieved.

With the mixer still running, slowly add the 1230 PLUS 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 primed and 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 the required 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 applied product should be rolled again after 20 - 30 minutes.

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 1230 PLUS 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 with a metallic base.

Equipment

Equipment care

Remove MASTERTOP 1230 PLUS from tools and equipment whilst still wet using Cleaning Solvent No. 2. Cured resin will require mechanical removal.

Yield

A 38kg unit will yield 21.19 litres of mixed material.

Primer:

MASTERTOP 1200 PLUS Resin only as supplied, mixed with 0.5ltrs of Cleaning Solvent No. 2 will yield 12.0 litres. Consumption will be 5-8m²/litre

Storage

Shelf life is upto one year when stored under cover, out of direct sunlight and protected from extremes of temperature. In tropical climates the product must be stored in an air conditioned environment.
