How to Keep Limestone Brick in Top Condition
But how do you do just that?
Water damage occurs either through splash back or rising damp, both which can cause issues for your brick and its surrounding ground. Splash back is the continual beating of rain against the brick, which soaks into the mortar and causes cracks in the joints. Rising damp results from seeping ground water, which leaves behind a possible tide line. Any moisture above a tide line will eventually evaporate, however, the leftover salt crystals will cause the brick and the mortar to breakdown.
Keep an eye out for water damage on a regular basis and budget for some possible repointing every 5-10 years.
If brick has been painted and you are now in need of removal, it can be a painstaking process. Chemical treatments work the best, however, it is best left to experts. Sandblasting should never be attempted as it causes lasting damage to the brick. If you try to sandblast it, the product will become rough and susceptible to build-up of dirt and moisture.
As previously mentioned, repointing is necessary when the mortar joints have become soft or damaged. Any damaged mortar should be carefully removed and reapplied in layers. However, when applying, the depth of the new layer should be twice the width of the mortar joint. Any mortar which is directly applied to the surface simply won’t hold up.
Light to Thorough Cleaning
It is a great idea to keep your bricks regularly cleaned to prevent any build-up of dirt, and it doesn’t take too much effort. For a light cleaning approach, use a vacuum cleaner to get rid of dust and loose debris, and to help clear soil away from bricks use a dampen mop with water.
For a more thorough approach to cleaning, use a natural stone cleanser that is suitable for limestone. Be sure to check the solution to see whether it is an appropriate solution, and don’t clean the bricks with any hard cleaning products as they can cause scratches.
Sealing helps to maintain your limestone bricks in better condition and for longer. Make sure you clean your bricks thoroughly before applying sealant, and make sure the sealant is suitable for limestone. Apply the sealant onto all areas of the brick installation and allow time for drying before a second coat. After, you need to reapply sealant every 1-2 years.
Sealant requires a dry surface, so make sure that after cleaning it is dry enough for an efficient application.
Although stains can occur on limestone regularly due its nature of high porosity, you can use a soft cloth or paper towel to blot them. Do not attempt to scrub them hard, and utilise a poultice to clear stains.
For extra maintenance of your limestone bricks, you can use a steamer, which helps to remove any dirt build-up which has been embedded in smaller pockets on the surface. It can also help to get rid of unwanted stains.
