Mixing Paddle - Collomix, WK 70 S, 70 x 400 mm, 41100-000

Collomix WK 70 S Mixing Paddle, 70 x 400 mm, 41100-000

Collomix WK 70 S is a mortar mixing paddle 70 mm in diameter and 400 mm long, catalogue number 41100-000. It is the smallest paddle in the WK range and is rated for batches up to 7 kg - a bucket of grout, a small run of screed, repair filler, tile adhesive for a single row. The shank is a plain 10 mm round, which clamps in an ordinary three-jaw chuck, so the paddle works in any drill or chuck-type mixer without an adapter.

Twin helix and mixing direction

The working end carries two helices that move material from the bottom upwards. That direction is what heavy mineral mixes need: dry powder is lifted off the bottom of the bucket into the water above, instead of sitting there as an unmixed lump under the paddle. The result is an even mix in fewer revolutions and less strain on both the operator and the machine.

What it mixes

Collomix recommends the WK range for ready-mixed mortar, cement screed, plaster and joint grout - compact, viscous materials with a high aggregate content. The paddle is not intended for liquid materials such as paints, coatings and primers, which need the opposite action, mixing from the top downwards.

Using it on site

Start the paddle already submerged and stop it before lifting it out - that way nothing is thrown out of the bucket and no air is beaten into the mix. Work at low speed, guiding the paddle slowly around the walls and across the bottom of the container. Clean it immediately after use, while the mortar is still wet; hardened material on the helices changes the shape of the working end and degrades the mix on the next batch.

Size and choosing between models

Diameter is what sets the batch a paddle can handle. At 70 mm the range is up to roughly 7 kg - beyond that the paddle bogs down and mixing slows. The larger models in the range, WK 90 S, WK 100 S and WK 120 S, cover 10, 15 and 25 kg respectively. Collomix paddles are made in Germany and are supplied singly.
