Mixing Bostik ULTRA LEVEL PLUS C700 requires between 4.8-5.0 litres of potable water per 20 kg bag and is best mixed with a forced action, high shear stirrer, powered by a heavy-duty electric mixing drill at approx. 600 r.p.m. – Add pre-measured water to a clean mixing bucket. – Gradually add Bostik ULTRA LEVEL PLUS C700 into the water whilst continuously mixing the contents of the bucket. When the entire contents of the bag have been added to the water, mix for a further 2-3 minutes to produce a smooth homogenous and fluid consistency. Placing Primed areas should receive the Bostik ULTRA LEVEL PLUS C700 as soon as possible to avoid dust and surface contamination affecting adhesion of the Bostik ULTRA LEVEL PLUS C700 to the Primer. – Pour the mixed material on the primed substrate. Depending on desired thickness, either allow material to seek its own level or spread the material with a steel trowel, spreader or squeegee. Keep the trowel slightly inclined to obtain desired thickness. – Pour the next mix of material. To ensure uniform consistency and flow application, it is advised that subsequent mixes are ready to enable continuous pouring. – For very large areas, Bostik ULTRA LEVEL PLUS C700 can also be applied using an automatic pump.
