If sagging occurs during application to vertical surfaces, the SewperCoat® Wet Spray should be completely removed and reapplied at a reduced thickness on to the substrate. Note: minimum applied thickness of SewperCoat® Wet Spray is 25mm. Equipment used must be clean and free of portland cement build up to avoid accelerated set. Water addition to be between 2.7-3.00L per 20kg bag of SewperCoat® Wet Spray. Please refer to the SewperCoat® Wet Spray application guide for further information. Application by hand trowel The SewperCoat® Wet Spray can be also be applied by hand trowelling onto areas of concrete where the application by the spray method is either not suitable or practical. When applying the material by hand trowel it is important that the same preparation and curing procedures are followed as the spray applied process. The concrete requires a rough surface which is either obtained by high pressure water blasting or grit blasting. The surface also requires thorough pre-wetting to provide a saturated surface dry (SSD) surface. SewperCoat® Wet Spray can then applied by hand trowel at a min thickness of 25mm. Care should be taken not to overwork material. The SewperCoat® Wet Spray should then be cured immediately after finishing using Concrete A99. Finishing SewperCoat® Wet Spray is finished by cutting to the required profile and closing with a steel trowel float. Wooden or plastic floats, or damp sponges can be used to achieve the desired texture. The complete surface should not be overworked. the surface will normally be finished immediately after spray application. Maximum size of application SewperCoat® Wet Spray applied by either the wet spray or hand applied technique should be applied up to natural expansion joints within the structure. Any expansion joints should be reflected through the SewperCoat® Wet Spray as well as any significant live cracks to ensure a defect free monolithic layer of material. The maximum area of application of the material is therefore determined by the number of joints within the concrete structure.

High temperature working At ambient temperatures above 35°C, the material should either not be used or appropriate measures should be taken to control the environment such as using ice water to mix the material and having temporary shading of the area where the material is to be applied. Please contact Parchem for further information about applying the material in temperatures above 35°C. Curing SewperCoat® Wet Spray is a cement-based repair mortar. In common with all cementitious material it must be cured immediately after finishing in accordance with good concrete practice. The use of Concure A99, sprayed on to the surface of the finished SewperCoat® Wet Spray in a continuous film, is recommended. Large areas should be cured as trowelling progresses without waiting for completion of the entire area. In fast drying conditions, supplementary curing with polythene sheeting taped down at the edges must be used. In cold conditions, the finished repair must be protected from freezing. Supply SewperCoat® Wet Spray is supplied in 20kg Bag. Coverage and yield Approx 2.4 Tonnes per m3 (Approx 8.3L/20kg bag) Limitations SewperCoat® Wet Spray is a protective mortar lining system, care should be taken when considering use for structural applications. Please contact Parchem for further information. Storage SewperCoat® Wet Spray to be stored in dry conditions, off the ground. In this case, it will retain its properties for at least 6 months.
