What can I use as a mortar plasticiser?

What can I use as a mortar plasticiser?

Washing-up liquid Washing up liquid is commonly used as a plasticiser in cement mortar. However, it is thought to affect the long-term structural integrity of the mortar as it can add too much air, thereby creating bubbles. The surfactants in washing up liquid may also produce foam if used in excess.

Do I need plasticiser for pointing?

Yes, Plasticisers do weaken the mortar. The reason for that is that the strength of the mortar is actually the strength of the cement. However, a plasticiser is used in CONCRETE and hardly ever in mortar, as the coarse aggregates need to slide over each other to form a dense packing in a mix of the three.

Do you have to use plasticiser in mortar?

Add plasticisers and other additives to the mortar mix to improve workability, but only if needed. Use only products specifically designed as a mortar additive. Use pre-mixed or factory-made mortar to ensure consistency throughout.

Can you use Fairy liquid instead of plasticiser?

“Washing up liquid affects the long term structural integrity of mortar and should never be used as a substitute for plasticiser.”

Can I use Fairy Liquid as a plasticiser?

How much plasticiser do I need for pointing?

Add Thompson’s Mortar Plasticiser to a rate: 150ml- 500ml per 50kg of cement, depending upon degree of plasticising required, or 2.5 lire per 200 litre drum of water.

What mix do you use for pointing brickwork?

What is a mortar and which mortar mix is best for brickwork? Cement and sand mixed with water makes concrete. Cement and sand, with the addition of plasticizer or lime (all mixed with water)makes a building or pointing mortar.

What Colour is mortar plasticiser?

Mortar Plasticiser, otherwise known as Pink Mix, is a pink coloured liquid admixture used in bricklaying and plastering mortars to aid workability and freeze thaw resistance. Reduces the likelihood of cracking and crazing.

Why is a plasticiser used in cement instead of mortar?

The reason for that is that the strength of the mortar is actually the strength of the cement. However, a plasticiser is used in CONCRETE and hardly ever in mortar, as the coarse aggregates need to slide over each other to form a dense packing in a mix of the three.

What is Thompson’s mortar plasticiser?

Thompson’s Mortar Plasticiser is a surfactant based liquid admixture for modifying cement mortar used in bricklaying and pointing mortar, back coats, renderings and blockwork. It is designed to improve plasticity without the addition of lime and increases resistance to freeze thaw cycles in the set mortar.

What is a plasticiser in bricklaying?

The term plasticiser, when applied to bricklaying Mortar is given to an admixture that is added to the mixer in small quantities in order to improve the properties of the Mortar It makes the mortar workable, it helps protect from frost during “curing” and it makes the mortar smoother allowing for a better tooled/jointed finish.

What is the hazard code for brick mortar plasticiser?

Mortar plasticiser for stronger, easier to use brick and block-laying mortar. Hazard safety codes: R22, R36, R38.
