## Description

Concentrated mortar admix improves workability, prevents shrinkage, and provides freeze/thaw resistance, delivering 25 times the strength of traditional plasticisers.

Review: Workable fluffy s&c mix - Gauge is terrible so i knocked ball through into main chamber and just meter it out into cap. Great stuff. Lovely fluffy mix and doesn't take up a load of room. 1 cap per 42l bucket of s&c mix worked well so will last ages.
Review: Easy to use - Keeps the muck workable for longer and if you need to take some down and rebuild it really easy the following day as it hasn't fully hardened yet.

## Questions & Answers

**Q: Could I mix this with acrylic paint and water as a pouring medium?**
A: I do not know is the direct answer, but, I would just suggest trying a small amount initially and take it from there. Let's face it. the stuff is cheap enough anyway, even if you have to throw the remainder of the 1 litre away.

**Q: does this replace lime completely?**
A: You can use your sand cement render or mortar with this completely, But, with Hydrated Lime in the mix, improves flexibilty and most important, breathablilty, so if your mix has not been specified and is for general everday use, such normal brickwoork, blockwork scratchcoat renders, topcoat renders, then this product can replace lime. Also this 1ltr bottle will make 25 litres, gaugeing instructions are on the back of the bottle, do not use more than the recomended dosage, unless you are a professional user.
I hope this helps.

**Q: Sorry for the thickness but is this also known as sbr? if not can i use both products with the cement? thanks.**
A: Hi, this is a plasticiser, SBR is used as a bonding agent, primer or water resistant product. Each product offer different benefits.

**Q: How much of this mix should be added to 10ltr of water? The instructions state an amount to add to 50kg of cement but that it must be added to the wat**
A: you need to work out how much water you use to a bag of cement which will be only 25 Kgs.  I use about 5ml. to a bucket of water .
