Trowel or screed application – both fine and coarse grades are suitable When applying to floors, a mix blend of equal parts Fine and Coarse Grades is most suitable. Apply Aegis Surface Primer # 1, to porous surfaces with brush or roller and allow to “damp dry” / become tacky. Do not allow the Sealer to completely dry – re-apply if substrate is porous. Do not apply Sealer more than 2 – 3 minutes ahead of application of the Aegis MSP. Horizontal surfaces: Pour the mixed Aegis MSP onto the surface, working it into all pores and irregularities. If using a screed, work in two directions, the second at 90 deg. to the first. Avoid over working Aegis MSP, this brings excessive moisture to the surface. Finish small areas, of 2 - 3 m², before moving on. “Finishing off” floors is best achieved with the use of a short nap mohair roller (for a “rough” finish) or a sponge trowel (for a “smooth” finish).These methods will help eliminate trowel marks from the finish. Caution: DO NOT place more AEGIS on the surface than can be finished in 15 minutes. Vertical surfaces: Apply Aegis MSP from a Halk onto the wall in small amounts, finishing each area before moving on. Wash all tools every 30 minutes. DO NOT allow Aegis MSP to build up on equipment. Clean up all spills and droppings immediately. Spray application – both fine and coarse grades are suitable Equipment needed. • Hopper Spray Gun. Nozzle size to be used: Fine application (0.5 mm thick) Use 3 or 5 mm Nozzle with 6 - 7 Bar Pressure. Thin application (1mm thick). Use 5 mm Nozzle with 5 - 6 Bar Pressure. Thick application (2 mm thick) Use 5 or 7 mm Nozzle with 4 - 5 Bar pressure. • 12-15 cfm (cubic foot per minute) compressor • Extension Leads and Air Lines • Large Bucket of clean water (20 litre pail is suitable) • Ground Sheet and Masking Tape (to prevent over spray) • Hand Finishing Tools (if necessary) Mask up all areas needing over spray protection. Thoroughly mix Aegis MSP as detailed previously Apply Aegis Surface Primer # 1, to porous surfaces with brush or roller and allow to “damp dry” / become tacky. Do not allow the Sealer to completely dry – re-apply if substrate is porous. Do not apply Sealer more than 2 – 3 minutes ahead of application of the Aegis MSP. Fill the hopper and begin spraying. Test spray a small area to confirm the technique and that the mix is at the desired consistency. Spray Aegis MSP on to the surface, using broad sweeps, side to side, from top to bottom. Move the gun at a constant speed and at 90° to the surface to ensure even application and texture. Ensure there is a 100 mm overlap to previously sprayed section. Clean gun, with running water (hose is sufficient), every 30 minutes. Do not allow Aegis MSP to build up in corners or curves; remove excess Aegis MSP with small scraper. Clean up over spray and floor immediately. When spraying horizontal surfaces (eg. patios, balconies, driveways etc.) allow Aegis MSP to visibly dry (2 - 4 hours at 25°C, ambient temperature) then sweep up all excess sand (overspray) from the sprayed surface. Curing periods Aegis MSP achieves full strength and resistance capability after a 28 day curing period however its characteristics provide for a high early strength and thereby allow an early practical use of treated surfaces. Recommended curing times (at 2 mm thick and 25°C): Light pedestrian traffic: 24 hours Off-form concrete basement 24 hours walls (prior to backfilling): Concrete block basement walls (prior to backfilling): 24 hours Animal traffic (pigs, cattle etc.): 48 hours Light vehicle traffic: 48 hours Waterproofing (prior to flood 7 days test): Heavy pedestrian traffic (high heels): 10 days Industrial traffic (steel wheels): 10 days Wash with “tap temperature” hot water (approx. 70°C): 10 days Resistance to most commercial acids and chemicals: 28 days Although Aegis MSP provides a waterproof surface it is not a flexible waterproof membrane. Where a flexible waterproof membrane is required please consider our Durafloor TC External Waterproof System or consult our website for information on Parchem’s range of flexible waterproof membranes.
