POLYBOND PVA
CHARACTERISTICS
► Bonds to most common construction material except PVC rubber and similar products
► Versitile
► Enhances adhesion
► Increases strength
FIELDS OF APPLICATION
– Adhesive Polybond PVA bonds with almost all kinds of building materials except PVC, rubber and polyethylene. When added with suitable filler, it can be used for fixing plasterboard, ceramic tiles, marbles etc.
– Bonding Agent Polybond PVA gives mortars, especially topping mortars enhanced bond strength. The wear resistance of screed treated with Polybond PVA is improved than that of a conventional sand and cement screed. The topping will be dust free, wear, water, oil and grease resistant
– Admixture Polybond PVA has a plasticizing effect which improves mortar application, increases the mechanical strength of screeds and renders, reduces shrinkage and has perfect adhesion even on smooth concrete
– Surface sealer Polybond PVA can be used as a surface sealer for concrete and floors to minimize the dusting and penetration of oils. It can be used as an effective primer on certain decorative coatings.
DESCRIPTION : Polybond PVA is a polyvinyl acetate based polyvinyl alcohol suspension used as a surface sealer, bonding agent and admixture for cement and mortar.
APPLICATION INSTRUCTIONS : As an adhesive for uneven surfaces Make a paste of Polybond PVA diluted with equal amount of water, cement and fine sand. The paste can be applied as an adhesive for fixing plaster boards, polystyrene tiles. To ceiling and walls. If the surface is highly porous, apply a primer coat of Polybond PVA mixed with water in the ratio of 1:3.
As a bonding agent for screeds, plasters and renders : The surface shall be sound and free from all contaminants, such as oil, grease, paint etc. Sealing of the surface is done with 1 part of Polybond PVA with 3 parts of water. Apply the bonding coat followed by the application of the render, screed or plaster normally. The same method shall be used to bond new to old concrete.
As an admixture : For normal to heavy duty flooring, 20-30L of Polybond PVA is the recommended to be admixed with100 kg cement.
For heavy renderings and cementitious toppings : Seal and prime the surfaces with Polybond PVA diluted with 3 parts of water. Prepare the render coat with 1 part of ordinary portland cement, 1 part clean washed sand and 1 part of Polybond PVA to 3 parts of clean water. Apply this to the tacky prime coat. 10 to 15L of Polybond PVA per 100 kg cement is recommended.
Note: Stir the contents of the product thoroughly, before use.
LIMITATIONS: – not recommended where permanent dampness occurs. – do not use below 5°C – do not over towel
CLEANING : Clean all the tools with water immediately after use.
STORAGE & SHELF LIFE : Store in a cool, dry place and keep away from all sources of heat and sunlight. In tropical climates, store in air condition rooms. The shelf life is up to 12 months in unopened condition and if stored as per recommendations. Excessive exposure to sunlight, humidity and UV will result in the deterioration of the quality of the product and reduce its shelf life.
HEALTH & SAFETY : As with all construction chemical products, caution should always be exercised. Protective clothing such as gloves and goggles should be worn. Treat any splashes to the skin or eyes with fresh water immediately. Should any of the products be accidentally swallowed, do not induce vomiting, but call for medical assistance immediately.
