LyzerBond WPA

(water proofing compound water tanks, water towers, roofs, terraces, trenches etc.)

LYZERBOND WPA is a mono- component aqueous base polyacrylic co-polymer elastomeric compound, produced by a unique emulsion polymerization technique. Used as water proofing compound for water tanks, water towers, roofs, terraces, trenches etc.

Physical Appearance

1. Colour Milky White
2. Viscosity 200 + / - 50
3. Sp. gravity 1.1 to 1.2
4. Storage stability Six Months


Mix one measure of LYZERBOND WPA with one measure of water and three measures of cement (Mix A). This mixture gives cement paste of traditional consistency. If weighing facilities are available, the mixture of one part of LYZERBOND WPA, one part of water and four parts of cement (w/w) gives approximately same consistency as above. Water may be added further if paste of different consistency is desirable. Requisite quantity of sand may be added to the mixture if required.

Water proofing for building terraces and Bathrooms

If coats of resins e.g. dammer or asphalt are applied previously for water proofing purpose, then these should be carefully removed as these coats do not allow bonding between old cement structure and new cement paste and good results are not obtainable.

Add water to above mentioned mixture (mix. A above) of cement paste with LYZERBOND WPA to get a free flowing watery consistency. Fill the cracks existing in the structure after pre cleaning and pre wetting. The mixture should percolate inside the cracks. Before this mixture gets dried apply the mixture of cement and LYZERBOND WPA prepared as stated above (i.e. Mix A) to make a top coat. Allow this to cure for 24 hours. Apply second coat and cure in similar manner.

For under ground tanks use the mixture of cement paste with LYZERBOND WPA as stated above with requisite quantity of sand.
Build the tank as usual and give three to four coats of mixture of cement and LYZERBOND WPA of above proportion but with watery consistency. In this manner old tanks can be repaired. Curing for at least 24 hours after each coat is essential. Mixture can be applied by brush or any other means. If water seepage is expected from out side to inside then outer surface should be treated with cement and LYZERBOND WPA.

Advantage of LYZERBOND WPA

1. Improves tensile, comprehensive and impact strength of cement.
2. Gives excellent water proofing.
3. Can be used for joining the old cement structure to new cement work.
(Apply self LYZERBOND WPA to old structure by brush, immediately)
before drying start new cement work containing LYZERBOND WPA.

Mechanism of LYZERBOND WPA

It has been indicated in research works that LYZERBOND WPA replaces part of water molecules taking part in the hydration of cement. The polymeric nature of LYZERBOND WPA when entered in cement complex gives higher strength and water proofing properties.

STORAGE: The product enjoys very good shelf life and warrants no particular storage conditions. However it is always advisable to have moderate conditions with the container being recapped tightly after use. 9 to 12 months if stored below 30c

Packing: 30 , 50 & 200 Kgs in Plastic Container
According to our best knowledge and technical experiments, the above data is true and accurate. Regarding to variety of consumption procedures, it is recommended to evaluate the information before use.
