Vandex Plug supplied by Parchem is such a product. Surface Preparation When applying Vandex Plug to existing concrete or masonry, all surfaces to be waterproofed should be clean, sound and free of concrete curing compounds, form release agents, paints and all other coatings, dirt and contamination. Where surface contamination exists, concrete surfaces should be prepared by water blasting, grit blasting or wire brushing in the area of the leak in order to remove the laitance in preparation to receive the Vandex Plug. Priming Priming is not required on good quality concrete or masonry substrates before applying Vandex Plug. Application Instructions Vandex Plug is supplied in the form of a dry powder and can be dry packed as a powder or applied by hand as a putty consistency after mixing with water by spatula. To mix, place 500 g of Vandex Plug into a small clean plastic container, add approximately 120 g of clean tap water and mix by hand with a spatula. Mix the powder and the water quickly for about 15 seconds. Scoop the mixed mortar out of the plastic mixing container by hand and knead the mix for 5 - 15 seconds as the temperature of the mix increases. The mortar should become quite warm and stiffen indicating that it is ready for application. The rapid setting time does not allow for any delay in application, ensure that all substrate preparation has been completed ready for immediate application of the plugging mortar. With gloved hands, roll the wet mortar between the hands like putty to shape it into an appropriate sized plug to fill the prepared rebate. Install the plugging mortar immediately ensuring that the correct temperature and consistency has been achieved and maintain firm hand pressure on the installed mortar for about 30 seconds until it has set. In large repairs, work from the lowest end of the repair towards the highest end, applying each new plugging mix next to the previous. Allow the mortar to set for 1 minute and using a trowel or spatula in a cutting action, cut away any excess mortar from the surface of the repair. After completing the repair, the effectiveness of the plug can be tested by sprinkling dry Vandex Plug powder over the surface of the repair. If the powder remains dry after 30 seconds, the repair has been successful. It is recommended that areas treated with Vandex Plug be overcoated with Vandex BB75, BB75-EZ or Cemelast. Applications where a very high water pressure exists behind the leak can be repaired more effectively by drilling a hole through the substrate and inserting a plastic tube to allow the water to flow and release the water pressure. Plugging can then be performed on the surrounding leakage points before removing the plastic tube and plugging the hole. Note: the water temperature used for mixing the Plug has a large effect on the setting time. Use cold water in summer and avoid using water from a hose that has been lying in the sun. In very cold winter conditions warm water may be used to accelerate the cure. Supply Vandex Plug: 15 kg resealable plastic pail Product Code: 751006 Storage 12 months in original container stored in cool, dry conditions ie; not exceeding 30°C. Storage above this temperature may reduce storage life.
