Non Hydraulic Mortar/Plaster - Coarse Stuff

How is non hydraulic lime plaster/mortar made?

Our non hydraulic coarse stuff lime plaster is made on site using our CHALK LIME PUTTY and a blend of NEWBURY GRIT SAND and WAREHAM WASHED SAND. It is supplied as a ready mix, meaning it is easy to use straight from the tub or bag.

  • Ideal for backing coats of internal plasters or exterior render.
  • The limestone and flint grit makes it ideal for flint work or pointing rubble stone as the combination maintains the white mortar colour with flecks of dark particles.
  • Available in 25kg tubs or 25kg bags. Or for larger orders, choose a half tonne bag, a tonne bag or a full pallet of 25kg bags.

What is non hydraulic lime?

Non hydraulic lime is lime in its purest form. It sets in contact with air through a process of carbonation.  The slow setting process means non hydraulic lime remains softer and more breathable. It is good for internal plasterwork and for use on soft backgrounds such as cob, soft stone or friable material. There is more information on the differences between hydraulic and non hydraulic limes in our WHICH LIME? User Guide.

Applying non hydraulic lime

Lime putty plaster has a long shelf life if kept within the airtight containers. If left for a period of time, it will start to settle and simply require 'knocking up' before use.

It is important that there is no risk of frost when applying non hydraulic lime mortars. Ice crystals forming within the lime mortar will greatly increase the time it will take the carbonisation process to take place. Using HESSIAN as an insulation barrier will protect from frost action and is vital during the winter months.

Teasing animal hair into the lime putty plaster just before use will increase the tensile strength of the plaster. The hair acts as a natural reinforcement and effective bonding key. We supply HORSE HAIR or GOAT HAIR in 100g bundles. Or have a look at our user guide on ADDITIVES FOR LIME PLASTER.

  1. A really attractive all-purpose mix - Christopher Gingell, 21st Sep 2018

    A really attractive all-purpose mix

    Posted by Christopher Gingell on 21st Sep 2018

    This coarse stuff knocks up in moments to an excellent, easy working mortar or pointing which cures to the right balance of strength without excessive hardness, for both softer and harder stonework. I have found the creamy oatmeal colour takes only the smallest amount of pigment when this is required.

  2. Finish made easier - Unknown, 29th Jul 2018

    Finish made easier

    Posted by Unknown on 29th Jul 2018

    Traditional material to match with existing mortar used to repoint and repair mixed stone and flint wall. Bagged ready mixed mortar with consistent grading makes working easier. Quality material at a reasonable cost.

  3. Consistent quality - Kate, 4th May 2018

    Consistent quality

    Posted by Kate on 4th May 2018

    Consistent high quality product. After a mix it gives a good textured mortar which is easy to work with and gives a good finish. Good colour match between bags. We used to mix our own, now don't bother! Good value when you consider the time saving and the better quality compared to mixing your own. Bags are strong enough to be lugged about without worrying that they'll split. Helpful delivery.

  4. Good stuff - Unknown, 24th Jan 2018

    Good stuff

    Posted by Unknown on 24th Jan 2018

    After knocking up this gives a very good buttery consistency easy to work, drying to off-white.

  5. excellent stuff - ingrid, 17th Nov 2017

    excellent stuff

    Posted by ingrid on 17th Nov 2017

    Just what was required for repointing some of the brickwork on our shabby chic 1920s chalet bungalow by the sea. Easy to use with a little practice - even for a total novice like me. Delighted with the results. It looks great.

    Works well even for those inexperienced in mortar repair

    Posted by David Flint on 25th Sep 2017

    A woodpecker, looking for insects ravaged the mortar on my 800 year old property. Bought a tub of premixed lime putty for repairs. It was easy to apply and it has hardened nicely. Colour does not really match but the whole building is so mottled, it does not really show. Good product

  7. consistently good - Unknown, 8th Sep 2017

    consistently good

    Posted by Unknown on 8th Sep 2017

    Im restoring a large Edwardian house previously under the care of Bodgit & Leggit Ltd for half a century or so. Cement strap pointing all over, gypsum on external walls etc etc. Bought a tub for some emergency repointing, it matches-ish the original mortar. Recently returned for 10 more bags to slowly repoint and rebuild the walls and plasterwork. Lovely stuff, breathable, flexible and very importantly for pointing, consistent in colour and texture. Great products and advice available at Lime stuff.

  8. Awesome product - Sean Williamson , 18th Apr 2017

    Great product; Easy to use with Just a Little Practice

    Posted by Martin on 8th Mar 2017

    Used for pointing. The 25kg tub comes ready mixed which takes out one more variable for the DIY-er. Worth getting a 1.5kg pouch first to check for colour/particle size.

  10. Easy to use - Michael lowrie, 15th Nov 2016

    Easy to use

    Posted by Michael lowrie on 15th Nov 2016

    Ready mixed and ready to go easy as that.
