All as per item no 2 here-in before but for second coat with 0.4 Ltr ( undiluted) PME diluted in 0.4 Ltr water to be applied uniformly on each 1.00 sqm area ( Second coat will be applied separately ) after drying and setting of First coat. Note for item no 2 and 3 :- No price adjustment shall be done if PME used is more than 0.6 Ltr and 0.4 Ltr per sqm of area in first and second coat respectively.

Material and labour for the removal of Rubber deposits from runway surfaces using waterblasting cum vaccuming system with suitable operating pressure so that the total Rubber deposits are removed from Runway (both Rigid and Flexible) surfaces by the method of water blasting cum vaccuming system with suitable water pressure without use of any chemical & causing no damage to the existing surfaces complete. The Tenderer shall take into consideration the following points while quoting the rates of this item :- Notes : (i) The work shall be carried out through authorised and qualified applicator. (ii) Total Rubber deposits should be removed and the Debries/Water to be Vaccumed Simultaneously leaving no FOD so that the Runway is available for operation immediately.
