SPECIFICATION OUTLINE
Plugging and sealing operations shall be carried out using Construction Chemicals Water Seal. The product must be stored, handled and used strictly in accordance with the manufacturer’s instructions.
APPLICATION
Preparation
All contact surfaces must be sound, clean and provide a good mechanical key. Remove all loose material, plaster, paint and oily deposits. Cracks should be cut back to a minimum of 20mm depth and width preferably undercutting. Avoid feather edging.
Priming
Where placing or plugging is being carried out in wet conditions, no priming is necessary. If concrete surfaces are dry, dampen with water before application of the Construction Chemicals Water Seal to assist adhesion.
Mixing
Mix powder approximately 4 parts by volume to water approximately 1 part by volume. For damp cracks and fillets mix should be semi-wet. For active water, mix should be a stiff consistency. Mixing should be carried out using a gloved hand. Do not mix more than can be placed within 2 minutes.
Placing
Apply the Construction Chemicals Water Seal into the crack or fillet using a fillet trowel. When working against water pressure, work towards the point of highest pressure and finish using a gloved hand forcing the material against the pressure until set. Cut off excess material from face within 3 minutes. Dampen fillet after application.
N.B. The use of warm water is acceptable at temperatures of 5ºC and falling.
Curing
Where heat generation takes place, cool with water for 10 minutes after application.
