MortarTubs

Mortar tubs typically range from around 65 litres for small jobs and repairs up to 350 litres or more for larger mixing tasks. For regular brickwork or rendering on a domestic build, a mid-size tub around 90-150 litres usually strikes the right balance between capacity and manoeuvrability. If you're mixing large volumes of concrete or running a busy site, go larger to reduce the number of mixes needed per day.

Most mortar tubs are moulded from heavy-duty polyethylene, which is lightweight, doesn't rust, and won't corrode from contact with cement or lime. Metal tubs do exist but are heavier, more expensive, and prone to corrosion over time with constant exposure to wet mortar. Polyethylene tubs also flex slightly, which helps knock off dried mortar residue more easily.

Yes, a good quality mortar tub is equally suited to mixing concrete, render, screed and other building compounds, not just mortar. The reinforced edges and thick base cope well with the abrasive nature of aggregate and the weight of a full concrete mix. Just make sure you're not exceeding the tub's stated load capacity when working with denser materials.

Look for tubs with a wide, stable base and reinforced rim, as these are specifically designed to resist tipping even under a full load. Always position the tub on level, firm ground before filling it, and avoid loading it unevenly to one side. Some tradespeople also chock the base on soft or uneven site surfaces for extra stability.

The easiest approach is to clean the tub while the mortar is still wet, using a hose or pressure washer and a stiff brush before it has a chance to cure. If mortar has already dried, a rubber mallet tapped against the outside of the tub often loosens larger chunks, followed by scraping and a wash down. Polyethylene tubs are far easier to clean than metal ones, as dried material doesn't bond to the surface as readily.

Many mortar tubs are designed to stack when empty, making them easy to store between jobs or transport in bulk on a trailer or van. Handles or lip designs on most models allow two people to lift and reposition a tub around site, though a loaded tub is best moved with a wheelbarrow, forklift or site buggy. Pairing your tub with proper site storage keeps it protected and out of the way when not in use.
