Description

Application

“Structural Ponding Test (If Any): Before any waterproofing treatment, a minimum 24 hours of structure ponding test is strongly recommended. Fill up the water at least up to the construction joint in the vertical wall area, monitor and repair the leaking area by PU grouting injection, this simple step helps the performance of waterproofing for long term. Primer Coat: Mix 1 portion of Obaproof WP-100HD with 3 portions of water. Slowly mix with an electrical mixer, and apply a thin layer of primer approximately at 0.2kg/m² onto the surface. 1st Coat Of Obaproof WP-100HD: After the primer coat, the 1st layer of waterproofing coating can be applied after 1 to 2 hours (depending on the weather condition), even if the surface is still wet or damp (but not ponding). Stir it slowly with an electric mixer, maximum 10% of water is allowed to add in. After the stirring, it is ready to be applied by brush, broom, roller or spray with a high pressure single component spray machine at dosage of 0.75kg/m². 2nd Coat Of Obaproof WP-100HD: Before applying the 2nd coat, stirring the material is still needed. If there is a fibreglass net in the system, 1kg/m² could be consumed to ensure the fibreglass net had been fully covered by the 2nd coat of Obaproof WP-100HD. Do not apply more than 2kg/m/coat or the crack could be found at the surface of material and might cause peeling off after curing. Curing Time: Primer coat: 1-2 hours. 1st Coat: 6-8 hours. 2nd Coat: 8 hours till fully cured. Ponding Test: After curing, a min. 24 hours of water ponding tests are required.”
