QUICK SETTING MORTAR FOR LEVELLING MANHOLE COVERS AND FOR REPAIRS FOR IMMEDIATE USE.

Desciption

WATMAT is a quick setting mortar, factory mixed with special cements, silica and additives. It is ready for use for levelling newly constructed manholes and urgent repairs to factory floors. 

Advantages

• For emergency repairs and resetting manhole covers on streets, public roads and concrete factory floors.
• Traffic can pass over the repair within two hours of application.
• Just mix with water.
• The addition of MAXCRYL to the mixing liquid produces an even stronger mixture.
• It adheres well to the substrate and its grey colour blends in with the concrete.
• It is non-toxic and odourless which makes WATMAT an ideal product for areas with little ventilation.
• Waterproof. Very low water absorption.

How to use
Surface preparation
The concrete substrate should be free from all loose particles, dirt, grease, oil or other contaminants. To achieve this, the surface should be bush hammered or grit blasted so as to expose good clean sound concrete.
Application and Mixing
For vertical patching and repair work WATMAT can be mixed with clean water and trowel applied. However, for a high performance finish and floor treatments, the inclusion of MAXCRYL into the mixing water at a rate of 1 part MAXCRYL to 3 parts water is necessary.
Setting
Once mixed to a mortar consistency, WATMAT can take from 5 to 20 minutes to set, according to the climatic and surface temperatures. Trials should be carried out to establish that whatever quantities you mix can be applied before the material starts to set.
Mixing
Mix the required amount of WATMAT with clean water. AS a guide, 25 Kg WATMAT requires between 4.3 and 4.6 litres of water.
Application
Mix the required amount of WATMAT, place it around the perimeter of the hole, place the levelling tool on top and inside. After twenty minutes the manhole cover can be put on, finishing with the final asphalt coat.

Types
In warm weather use WATMAT "S" and in cold weather, where temperature is lower than 15 degrees C, use WATMAT "W". Both of these types of WATMAT can be used together, either mixed together or in separate applications. They are completely compatible and there is no colour difference.

Suggestions

• Do not apply at temperatures below 5° C or on freezing surfaces.
• Do not re-use previously mixed amounts of WATMAT.
• Use only clean water.
• Do not mix WATMAT with other products.
• Do not re-temper
