RAKAM 304-RAK Bond PVA

Public Channel / Data Sheets

(PVA Bonding Agent)

RAK BOND-PVA is a polyvinyl acetate latex emulsion used as a surface sealer, bonding
agent, admixture for cement and mortar.

Uses

Adhesive:
RAK Bond-PVA bonds with almost all
building material except PVC, rubber and
polyethylene. It can be used to bond
plaster board, ceramic tiles, marble, glass,
bricks, wood, leather etc. when added with
suitable filler.

Bonding Agent

This gives mortars, especially topping
mortars very good resistance. The wear
resistance of screed treated with RAK
Bond-PVA is excellent compared to a
conventional screed with common mortar.
The topping will be dust free, wear proof,
water, oil and grease proof.

Admixture

RAK Bond-PVA has a plasticizing eect
which improves mortar application,
increases the mechanical strength of
screeds, reduces shrinkage and has
perfect adhesion even on smooth concrete.

Storage

Up to 12 months in manufacturer's sealed
containers stored in a cool, dry place away
from high temperatures.

Curing

Curing occurs within 3 - 7 days.
Points to be noted:
RAK Bond-PVA is not recommended
where permanent dampness occurs.
Do not use below 5°C
Over trowelling is to be avoided
Always follow the mixing ratio
and instructions.

1. As with all chemical products, caution should always be exercised. Protective clothing, such as gloves and goggles, should be worn (see packaging for specific instructions). Treat any splashes to the skin or eyes with fresh water immediately. Should any of the product be accidentally swallowed, do not induce vomiting but call for medical assistance immediately. Ensure the container is available for the medical attendant to examine any relevant instructions and contents details. Reseal all containers after use and ensure product is stored as instructed on the safety section of the labelling. HEALTH AND SAFETY RAK BOND-PVA is a polyvinyl acetate latex emulsion used as a surface sealer, bonding agent, admixture for cement and mortar. (PVA Bonding Agent) 304 - RAK BOND-PVA Adhesive: RAK Bond-PVA bonds with almost all building material except PVC, rubber and polyethylene. It can be used to bond plaster board, ceramic tiles, marble, glass, bricks, wood, leather etc. when added with suitable filler. USES For uneven surfaces, or gaps to be filled, RAK Bond¬PVA is diluted with equal amount of water to obtain a paste with plaster, cement or with fine sand and the paste is applied. This paste can be applied as an adhesive for plaster boards, polystyrene tiles, etc. to ceiling and walls. If the bonding surface is more porous, add 3 times the amount of water to RAK Bond-PVA and prime the surface. As a bonding agent for screeds, plaster and rendering, the surface should be sound and free from all unwanted materials, such as oil, grease, paint, etc. Sealing of the surface is done with 1 part RAK Bond-PVA with 3 parts of water Then apply the bonding coat (1:1) and render, screed or plaster normally. The same method is used to bond new concrete to old. As an admixture, RAK Bond¬PVA gives a crack free, thin floor screed. For normal to heavy duty flooring 20-30 kg/100 kg cement is recommended. APPLICATION This gives mortars, especially topping mortars very good resistance. The wear resistance of screed treated with RAK Bond-PVA is excellent compared to a conventional screed with common mortar. The topping will be dust free, wear proof, water, oil and grease proof. BONDING AGENT Ensure that the substrate is stable, sound thoroughly clean and free from oil, grease and any loosely adhering material. Apply a sealing coat of RAK Bond-PVA diluted with 4 parts of clean water and allow to dry. Apply a bonding coat of RAK Bond-PVA diluted with an equal volume of water and lay the new concrete while this coat is still tacky. For maximum bond strength, add 5kg of RAK Bond-PVA per 100kg of cement. BONDING NEW CONCRETE TO OLD RAK Bond-PVA has a plasticizing eect which improves mortar application, increases the mechanical strength of screeds, reduces shrinkage and has perfect adhesion even on smooth concrete. ADMIXTURE RAK Bond-PVA can be used as a surface sealer for concrete and floors to minimize the dusting and penetration of unwanted oils. It can be used as an eective primer prior to certain decorative coatings. SURFACE SEALER Curing occurs within 3 - 7 days. Points to be noted: RAK Bond-PVA is not recommended where permanent dampness occurs. Do not use below 5°C Over trowelling is to be avoided Always follow the mixing ratio and instructions.
