^^^^^^^^^
What he said, a good squirt.

Be careful though. Some folk add it AFTER mixing, ie at the final mix stage. It can cause whjat looks like an excellent consistency mortar to become liquid again[blink]

Hi

Fairy liquid plasticises mortar, but adversely affects its final strength and durability.If you are laying a few blocks at home the fairy liquid is not going to be a problem and it is better than nothing.

 Lignosulphonate type plasticisers are the proper product and agin it is important to gauge properly – too much will affect the strength of the finished brickwork.

The amount of water required to reach a specific workability will be reduced. The use of plasticiser also allows less cement - the ratios change - see plasticiser pack for details.

It works by lower the surface tension of the water; thereby increasing it’s wetting properties.

Good quality Plasticiser will also enter air bubbles into the mix,  which give expansion paths for water to freeze into during cold weather - preventing cracking.

Try any of Le plastifiant, Le Fluidifiant or Le Foundifiant.
