MASTERTOP 1110 T 

Description

MASTERTOP 1110 T is a two component, water dispersible, epoxy resin coating, designed to seal and protect concrete, timber and asphalt floors in light duty situations.

Primary uses

MASTERTOP 1110 T gives good general protection for concrete surfaces and provides an easily cleaned, non dusting finish in numerous industrial and commercial applications. The system is free of organic solvents and will not taint foodstuffs.

MASTERTOP 1110 T can be successfully applied to damp concrete surfaces making it particularly suitable for wet process industries, where a dry substrate may be difficult or impossible to obtain.

MASTERTOP 1110 T offers good resistance to a wide range of chemicals and aggressive liquids, but as in all corrosive situations a full analysis of operating and exposure conditions is required followed by reference to chemical resistance data, to ensure product suitability.

MASTERTOP 1110 T can also be applied to act as a combined sealer / coating / curing membrane provided that the concrete has hardened sufficiently.

MASTERTOP 1110 T is used extensively in the following application areas as a sealing coat and wearing surface to epoxy toppings and screeds.

• Dairies
• Abattoirs
• Fish and meat processing plants
• Warehousing
• Soft drink and beverage production
• Manufacturing and food processing
• Bakeries
• Wash and changing room walls
• Pharmaceutical factories
• Industrial and commercial kitchens

Advantages

• Moisture tolerant
• Economical
• Easy application
• Solvent free, non tainting
• Easily cleaned
• Dust free surface
• Ease of maintenance
• Good bond to dense surfaces

Packaging

MASTERTOP 1110 T is supplied in a 4 litre unit.

Typical properties*

Hygiene

From all available information it has been found that MASTERTOP 1110 T shows a minimal risk of tainting foodstuffs during and after complete cure has taken place.

Application procedure

Preparation:

MASTERTOP 1110 T can be applied to a clean, dry or damp but not wet substrate free from dust, dirt, oil, grease and other contaminants. A clean surface will ensure improved adhesion between substrate and coating.

The method of surface preparation will be dictated by the size of area to be treated, location and degree of contamination.

New construction:

Floors to be coated or overlaid should be at least 28 days old unless water reducing admixtures have been incorporated. (Consult BASF ME's Technical Services Department for advice). The removal of laitance and contaminants is best achieved by mechanical means such as vacuum recovery shot blasting.

Existing concrete:

All contamination must be removed and a sound clean substrate exposed. Mechanical means of preparation are preferred followed by the removal of dust and other loose debris using an industrial vacuum.

In areas of deeply penetrating contamination by oils, greases and fats, hot compressed air, treatment followed by impregnation with a low viscosity sealer / primer is the recommended treatment.

Prior to application, MASTERTOP 1110 T should be stored under cover and protected from extremes of temperature which will cause inconsistent workability and cure times of the mixed material. During application in cold conditions, correct conditioning is essential, but application should be halted if the ambient temperature is likely to fall below 10°C. Consideration should be given to the substrate or base slab as it is likely to be considerably colder than the ambient air temperature.

Mixing:

MASTERTOP 1110 T is a two component product consisting of base and reactor components. The base component should be mixed before use to redistribute any settlement that may have occurred during storage.

To the pre-mixed base add the complete contents of the reactor container. Using a slow speed drill with a suitable mixing attachment, mix for 1-2 minutes until a uniform streak free consistency is achieved. MASTERTOP 1110 T is supplied in preweighed units; at no time should packs / units be split.

Priming:

Substrates that are porous should be primed using MASTERTOP 1110 T diluted with up to 10% by volume of water per 4 Iitre pack. Coverage will be approximately 8-10m² / Iitre / coat.

Mixing should be as described above. Application should be by short haired roller or airless spray.

Coating application:

Apply 2 coats of MASTERTOP 1110 T at 5-8m²/coat and allow at least 6-8 hours but no more than 48 hours between coats.

Apply the second coat at right angles to the first.

MASTERTOP 1110 T should be allowed to cure for 48 hours prior to receiving light traffic. Full cure is achieved after 7 days. As with all water based systems, good ventilation and air movement is required to assist drying, especially in damp conditions.

Slip resistant coatings

Where slip resistance is required MASTERTOP SLIP RESISTANT AGGREGATE NO. 1 (SRA NO. 1) is broadcast into the wet base coat, to saturation. Leave overnight to dry then remove excess aggregate by sweeping or vacuuming, before applying the top coat.

When a slip resistant finish is applied in areas that will be wet and / or suffer from chemical spillage, a primer coat must always be applied.

Consumption:

BASE COAT 6.5 - 7 m² / litre

AGGREGATE 1.5 - 2 kg / m²

TOP COAT 5 - 6 m² / litre

Coverage will vary according to the nature of the substrate.

All calculated usages assume constant thickness on a regular substrate. Failure to achieve the required surface regularity will lead to additional material being used.

Storage

Store under cover out of direct sunlight and protect from extremes of temperature. In tropical climates the product must be stored in air conditioned environment.

Failure to comply with recommended storage conditions may result in premature deterioration of the product or packaging. For specific storage advice consult BASF ME's Technical Services Department.

Safety precautions

As with all chemical products, care should be taken during use and storage to avoid contact with eyes, mouth, skin and foodstuffs (which can also be tainted with vapour until product is fully cured or dried). Treat splashes to skin and eyes immediately. If accidentally ingested, seek medical attention. Reseal containers after use. For further information refer to the material safety data sheet.
