Uni Top Metallic

The base concrete should have a minimum cement content of 300 kg/m³ with low slump of 40-60mm. Improves the quality of concrete mix and enables low w/c ratio to be kept. By using Uni Plast NP, workability of base concrete can be improved with a low w/c ratio.

The base concrete must be laid in accordance with good concrete practice either in bays or long strips. Particular care must be taken at the corners and edges of the bays to obtain good compaction and to maintain level for subsequent trowel operations. If too much of free water is seen on the surface, water content in subsequent concrete must be reduced to obviate the presence of free water. The time of the application is very important in order to derive full benefits of Uni Top Metallic. If Uni Top Metallic is applied too early, it will absorb water, hard wearing aggregate may sink to the bottom. If application of Uni Top Metallic is delayed, no moisture from the concrete surface will be available to hydrate Uni Top Metallic, resulting in poor pitted surface. As a guide, the application should be made between 1 Hours-1.5 Hour i.e. when surface water on concrete is completely evaporated. (When tested with Thumb, it leaves an impression but concrete does not stick to the Thumb). (Separate Application guide is available on request). The application rate is 5 kg/m² of Uni Top Metallic Powder.
The application is made in two stages :
1. First 50% of the required material is broadcast evenly and when the surface darkens with the absorption of water, the surface is floated.
2. The second application is made immediately, by evenly broadcasting the balance 50% material and when the surface has darkened with the absorption of water, the surface is floated. Power floating would be ideal. Floating is recommended with half or full disc. The second troweling is done after the surface has sufficiently stiffened i.e. after two hours after the first troweling, to close any pores and remove any undulations on the surface. Final hand trowelling is recommended to remove any disc marks.

After final troweling, as soon as the surface has hardened sufficiently, to prevent damage, it should be covered with a polythene sheet and made air tight by placing sand all round the sheet for a minimum period of 7 days. Alternatively curing by ponding is recommended for a minimum 7 days.

Tools and equipment can be easily cleaned with a clean water.

Do not apply over concrete containing calcium chloride.
