5 Best Uses for Lime Mortar 5 Best Uses for Lime Mortar
With origins in Ancient Greece, lime mortar is one of the oldest types of mortar used by man. Although it’s been superseded by Portland cement in new construction, it still has its uses in buildings. Sometimes the old materials offer things that newer ones just can’t, so lime mortar can still be very useful. As people rediscover building materials that are environmentally friendly the popularity of lime mortar continues to increase.
Although lime mortar won’t eliminate mold, it can help to ensure that it doesn’t happen in the first place. As lime mortar is vapor permeable and breathable, moisture isn’t trapped in the walls, and moisture is one of the greatest causes on mold in buildings.
If you are rebuilding after taking care of a mold problem, the use of lime mortar can help keep the problem from coming back. Lime plaster is an excellent material when dealing with any problem associated with dampness.
Lime render, as lime mortar was known when used inside buildings, can be very beautiful. If you want to give an older veneer to your house, applying lime mortar to your interior walls can help achieve this. Note that it should only really be used over lath rather than over drywall.
Lime mortar can be finished with the same smoothness as all other plasters. As lime plaster is breathable it improves the air in the house by removing the moisture from the interior of the house.
If you’re building a wall in your garden, try using lime mortar. This is the traditional method and still the best. The plasticity of lime mortar is such that it helps the quick adhesion of the stones to mortar, while the breathability of the lime mortar gives it flexibility and strength.
As moisture passes through the lime plaster and the plaster hardens into calcium carbonate, it gives increased strength to the wall. If you’re putting up a wall you want it to stand for several decades at least.
A flagstone driveway will work very well with lime mortar. The mortar is plastic enough to allow easy laying of the stones. Once the lime has a chance to react with the carbon dioxide in the environment it become calcium carbonate. That stiffens the mortar to hold the flagstones well, but it never sticks to the stone or becomes rock hard the way cement does. That stops the mortar cracking when under weight, which might happened when you drive and park a car on the driveway. This give increased durability and life to the driveway secured with lime mortar.
If you have an old house-this means historic, not just one that’s been around 100 years—it will probably use lime mortar in its construction. In order to keep the house in its proper condition you should use lime mortar for any restoration work. It’s easy to work with, environmentally friendly, and will give the kind of finish that fits in with the older building.
