PVA BOND EX4400/Bonding agent for concrete
Bonding Agent & Plasticizer for concrete & Plaster)
CHARACTERISTICS
Ultra Bonds to most common construction material except PVC rubber and similar products Versatile Enhances adhesion Increases strength
FIELDS OF APPLICATION
Adhesive
Ultra bond PVA bonds with almost all kinds of building materials except PVC, rubber and polyethylene. When added with suitable ller, it can be used for xing plasterboard, ceramic tiles, marbles etc.
Bonding Agent Ultra bond PVA gives mortars, especially topping mortars enhanced bond strength. The wear resistance of screed treated with Ultra bond 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
Ultra bond 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
Ultra bond PVA can be used as a surface sealer for concrete and oors to minimize the dusting and penetration of oils. It can be used as an effective primer on certain decorative coatings
DESCRIPTION
Ultra bond 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 Ultra bond PVA diluted with equal amounts of water, cement and ne sand. The paste can be applied
As an adhesive for plaster boards, polystyrene tiles. To ceiling and walls. If the surface is highly porous, apply a primer coat of Ultra bond 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 Ultra bond 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 ooring, 20-30L of Ultra bond PVA is recommended to be admixed with100 kg cement. For heavy renderings and cementitious toppings Seal and prime the surfaces with Ultra bond 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 Ultra bond PVA to 3 parts of clean water. Apply this to the tacky prime coat. 10 to 15L of Ultra bond PVA per 100 kg cement is recommended. Note: Stir the contents of the product thoroughly, before use
