Virsun Sun Block Bonding Adhesive is a factory prepared blend of carefully selected raw materials, portland cement and graded aggregates and polymers. Designed for use with water to produce high strength thixotropic mortar, for laying aerated lightweight concrete, fly ash bricks, cement hollow blocks, cellular concrete blocks or smoothing over the block work surface in layers of up to 12mm thickness, that meet and exceed the requirements of National and International Approximately 200 sq.ft. per 50 kg bag when used at 2-3mm bed thickness Coverage is based on smoothness and evenness of the substrate, size of blocks used and the thickness of mortar used.
If a plaster/leveling mortar bed is applied, ensure that it is cured for at least 7 days to achieve proper strength before application of adhesive for construction of block work.
Ensure the substrate is clean and free from impurities like dust, dirt, debris, oil, grease, curing agents, existing paints, loose plaster etc.
Mixing The product can be mixed by hand Pour water in a clean container and then add the powder SUN Block adhesive until the mixture becomes creamy and plastic. Leave the mix to slake for 5-10 min and remix before use. Mix only sufficient quantity of adhesive for the immediate need.

Thin bed mortar for laying blocks Before placing mortar, ensure the block work to be dry and surfaces cleaned properly. Place the mixed mortar on the block work In thin layers of 2 to 3 mm (or as required by engineers at the site) using ta rowel and place the next layer of blocks on the mortar. Keep Joints between the blocks as required by the site engineers and fill the Joints with the mixed mortar, using a trowel. Check the plumb of the wall while laying the blocks to keep the walls perfectly vertical to the plumb.
Smoothing over the block work Before placing mixed mortar, apply a bonding layer of 1 to 2mm thick SUN Block Adhesive mortar using a trowel pressing down on the block work. Then apply SUN Block Adhesive at a thickness of 8 to 10mm and smoothen using a sponge or rubber / wooden float. When installing large blocks, spread higher thickness of SUN Block adhesive. Select proper type of notched trowel.
As Adhesive to install tiles SUN Block Adhesive can be used as a thin-set adhesive to Install tiles on SUN Block/Fly ash brick walls. Use a suitable notch trowel to achieve the desired thickness of adhesive for installation of tiles on the wall. The most Important standard to keep in mind Is to ensure that the piece of block Is completely bedded In the mortar or adhesive with 100% coverage after Beat In.
Wet the surface and remove the excess water before applying the adhesive. Ensure the area Is shaded from sunlight. The adhesive shall be applied with the flat side of the trowel using a scraping motion to work the material into good contact with the surface to be covered. Additional mortar is then applied withthe notched edge of the trowel.
