Structural defects must be repaired prior to the Aegis MSP application. Application The substrate should be clean, sound and free from loose material and contamination such as curing compounds, oil, paint and grease. New concrete should be at least 14 days old. Laitance should be removed by acid etching followed by neutralising and water flushing, light scabbling or captive shot blasting followed by vacuuming to remove dust debris. Oil and grease must be removed. Large cracks (non moving) Use an angle grinder to create a “V” along crack line. Apply Aegis Surface Primer # 1 to the “V”, along crack line then fill the “V” with Aegis MPS before the general application of the Aegis MSP to the entire area. Mixing equipment • Heavy duty spiral mixers such as a Festo 2 speed stirrer is suitable to mix in a 20 litre plastic pail • Rotary cement mixer 2 - 3 cubic foot capacity is also suitable for larger applications Mixing instructions Aegis MSP is a two-component, pre measured product, (packed in a sealed plastic 20 lt. pail) and comprising a 1.4 litre bottle of “wet mix” and 18.6 kilograms of “dry mix”. Thoroughly shake the bottle of “WET MIX” and pour into a clean cement mixer or 20 litre pail. Water content: the following amount of clean water should be added to “Wet Mix” liquid to provide the appropriate consistency of mixed material. The Wet Mix bottle can be used to measure the added water. it has a volume of approx. 1.5 litres. • Trowel & Screed Application 1.5 litres ie.1 full bottle (1.5 litres) of water • Squeegee & Broom Application; 2.1 - 2.5 litres • Spray Gun Application; 1.75 - 2.0 litres Note: refilling the “wet mix” bottle, to add the water will ensure transfer all of the “wet mix” to the mixing container. Water content will vary between jobs, according to local conditions and ambient temperature. Only add extra water while mixing. DO NOT add water to the applied product. Strength, colour, consistency and final finish will be affected by excessive water. Slowly, add all the “dry mix” to the “wet mix” (and water), while mixing in the cement mixer or pail. Further small amounts of water, up to 200 ml, may be added to obtain the desired consistency. Mix thoroughly for three minutes to produce an even consistency then allow to stand for two minutes before applying to the prepared / primed surface. Squeegee or broom application – use Aegis MPS Fine grade only. 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. Pour mixed Aegis MSP onto surface to be coated in a quantity which can be quickly worked, with the selected squeegee or broom. Pull Aegis MSP in front of squeegee (or broom) while applying firm downward pressure on the “blade”. This will ensure Aegis MSP is forced into all surface pores and irregularities and produce a good bond. Apply the first coat as thin as possible. Bonding will be better and the second coat will be easier to apply. After the first application has dried for 30 minutes, trowel fill any obvious holes before applying the second coat to the required thickness and finish. Wash equipment every 30 minutes, do not allow Aegis MSP Aegis® MSP
