Sandstone stairs are a practical addition to your outdoor space that looks great. However, wear and tear from the elements and repeated use might cause them to deteriorate over time.
This essay will instruct you on fixing your sandstone stairs to look and work like new ones again.
What is Sandstone?
Sandstone is well-liked for its old-fashioned charm and natural tones. Both indoors and out, it is used for constructing walls, hearths, and floors. Sandstone is both inexpensive and long-lasting.
Problems with Sandstone and How to Fix Them
Older natural stone buildings often have worn surfaces that pose aesthetic, safety, and structural problems. Natural stone, especially sandstone, has a shorter lifespan than other façade materials like brick. Recognising and appreciating this distinction is crucial for restoring, repairing, and preserving this material.
Why Things Are Getting Worse
The first thing to do when planning a repair project is to identify the cause of the damage. It's usually because of the weather, climate, or surroundings. Human error, such as shoddy construction, overloading, or patchwork, can also contribute to deterioration.
Common causes of stone degradation include the following:
- Changes in the atmosphere
- Joint material deterioration due to lack of maintenance
- Poor work done in the past
- Subpar reassurances and gaudy embellishments
- Ant-freeze salts
- Bad paint job
- Freeze-thaw damage and other environmental factors
Types of Deterioration
The type of damage that the stone shows is typically attributable to the cause of the deterioration.
The most common forms of stone degradation are briefly described below.
- Subfluorescence, efflorescence, staining, and biological growth
- Splitting, separating, or peeling apart
- Scaling and exfoliation
- Erosion and breakdown, the loss of minerals that formerly held things together
How to Fix Sandstone Steps
- Verify the stability of the current stones by probing them with a screwdriver. The repair will involve removing loose stones, especially those near the step's edge. Stones that are firmly set in their places won't move.
- Remove stones by chipping away at the mortar between them carefully. Use the chisel and hammer to chip away at the mortar between stones rather than the stones themselves. Begin by chipping away at the joints surrounding the stones, and if those are loose enough to be removed, continue on to the joints underneath the stones. Do not pry the stone up; doing so will likely cause it to shatter.
- Keep chipping away at the mortar that held the stone to the underlying concrete. To keep the steps at a consistent height, this mortar must be removed before a new layer can be spread without raising the stone over the others. After the old mortar has been scraped away, a masonry brush can remove any remaining dust or aggregate before water is poured over the stone to stop it from absorbing moisture from the new mortar.
- Spread some concrete additive on the ground and ensure it gets into all the cracks between the stones and the mortar. This will help the new mortar adhere to the old masonry surfaces, making the stones less likely to become dislodged.
- To make mortar mix, combine it with water in a bucket and stir until it approaches the consistency of oatmeal. Pack mortar into the mortar joints surrounding the repair area using the margin trowel. After the hole has been packed, fill it with mortar using a trowel. Press down at an angle on the mortar mixture at about half an inch intervals to make furrows. Note: Avoid adding excessive mortar mix to any of the steps; doing so could make pressing the stone down to the desired depth impossible.
- Spread mortar mix behind the sandstone using a trowel. Press the stone into the mortar bed and wiggle it gently to remove air bubbles and extra mortar. Tap it with the trowel handle until it is level with the rest of the stones.
- Pack the mortar into the crevices and the joints surrounding the stone with a trowel. Once the aggregate is sufficiently compacted, you can reproduce the rustic appearance by lightly dragging the joints with a paintbrush.
- Remove excess mortar from the stone's surface and buff off rough spots with a sponge and water. Wait to sponge the joints again until you give the region a few minutes to dry. Wait to use the stairs until the mortar has fully dried.
Solutions for Cracked or Loose Stone Steps
Stone steps that are loose or broken are a regular source of frustration for homeowners. Fixing loose stone steps that are breaking apart might be challenging.
We've come up with some pointers to assist you in figuring out the best and simplest ways to set your stone stairs in place so that you have safe, even ground to walk on while entering and exiting your home or using your backyard patio.
Apply an epoxy glue.
Two-part epoxy adhesive is a popular choice among contractors for this purpose. It binds strongly to the mortar foundation and the natural components atop the step.
Before placing a thin bead of glue under the stone step, follow the manufacturer's directions for mixing the adhesive with the resin.
Experiment with the chalk line
If you don't have any epoxy adhesive or resin on hand, draw a chalk line from the top of the step to the ground and use that as a guide to ensure that your mortar is drying at the correct height. Build a simple wooden frame for your stairs and secure its corners using wood stakes. Add water to the quick-drying cement and pour it in as instructed. Be sure to fill it up evenly on all sides so that it dries flat.
Drill holes and insert pins.
To drill into brick or other masonry, use a drill bit and a smooth board one inch thick. Then, you should make holes in the stone just deep enough to secure pins. Make sure your board is the right size by first measuring the width of your step. Your wooden mould will need holes drilled at the four corners, along each side, and in the middle of each face. Bolts can be inserted from the bottom up via these holes. Mount washers on top of them, then spin them down until they're tight. Tighten bolts by turning them clockwise with a wrench until they contact the stone's underside. Cement or similar grout mix should fill the voids, and the mould should be left overnight to dry mortar.
Use bricks as bumpers.
Rip two pieces of 2-by-2 lumber using a saw into 18-inch-long, 1-by-1/2-inch-wide strips. Eight or nine brick blocks should be 12 to 18 inches apart and nailed together across their flat surfaces. You can fix the wobbling step by placing bricks under it. Then, compress them by sitting on the stairs while turning a half-inch metal bolt into each block.
Make use of stone wedges.
Use a grout saw, chisel, and hammer to remove loose mortar between stones. This will create grooves for small, triangular stone wedges in stone fractures. When positioned near seams within grooves, the wedges' pointed ends will press against the lower edges of the stepping stones above. Apply thin-set mortar underneath the wedges and press firmly to keep them in place.
You might use a powerful cement adhesive.
To prepare a thick but pourable slurry:
- Combine two parts: cement, sand, and masonry adhesive in a large tub.
- Wearing rubber gloves, pour or scoop the mixture into the spaces between the stones.
- If the opening is too big for pouring, use a hard wire to push the mixture through. The mortar must dry for a full day before you may walk on it again.
Make use of wooden wedges.
Place wooden wedges behind each set of shaky stone steps. Place them along the seams inside the grooves, pressing firmly against the lower edges of the other stepping stones above. Rain or fog will cause the wedges to swell and push through the gaps between the stones.
Replace loose stones.
You can get replacements for missing stones at a hardware store, a zoological supply house, a garden centre, or a stone dealer. Before you try to fix your stone step, you need to determine what kind of stone it is.
Stick together the loose stones.
Follow the label directions for combining the epoxy adhesive and activator. Then, use it to fill the spaces between the stones in your outdoor staircase. While the adhesive is still wet, press matching replacement stones into position. Only dare step back upon those steps once it's completely dry.
Use grout to seal joints.
Fill outdoor stair gaps and crevices with professional masonry or concrete grout according to package specifications. After waiting an hour, apply another coat over it to fill in any remaining gaps. Cover the patched area with plastic wrap (secured with tape) and leave it overnight. After the grout has dried overnight, take it off. After 48 hours, the grout will be fully cured, and the stone stairs can be used again.
FAQs About Masonry
Stains on sandstone can be challenging to remove. You can try a mixture of water and a mild detergent, but it's advisable to consult a professional for tough stains.
The frequency of sealing depends on factors like weather conditions and foot traffic. Generally, it's recommended to reseal your sandstone steps every 1-3 years.
Use a soft brush or mop, mild detergent, and warm water to clean sandstone steps. Avoid abrasive cleaners or high-pressure washing, as they can damage the surface.
Matching the colour of repaired sandstone with the original stone can be challenging. Professional stone masons can help blend repairs for a more seamless look.
Minor repairs like filling cracks can be done as a DIY project, but for major repairs or replacements, it's usually best to hire a professional who specialises in working with natural stone to ensure long-lasting results.
Sandstones and the Proper Way to Clean Them
Learning about Sandstone
Understanding the special qualities of Sandstone is crucial before beginning the cleaning process. Sandstone, a sedimentary rock, comprises tiny shards of minerals, other rocks, and even organic matter the size of sand. It can be found in various hues and textures, each possessing unique qualities. If you know what kind of Sandstone you have, you may use that knowledge to select the right cleaning chemicals.
Get Your Stuff Together:
Sandstone requires the following items for proper cleaning:
Broom or brush with soft bristles
Loose dirt and debris can be brushed off the Sandstone using a soft, bristled brush or broom.
Acid-free disinfectant
Find a cleanser that is safe for natural stone and has a neutral pH. Harsh chemicals easily damage sandstone, so stay away from it.
A bucket of hot water
Dilute the cleanser with warm water, then rinse the Sandstone in a bucket.
Cleansing sponges and rags:
Sandstone should be cleaned and dried with soft, nonabrasive towels or sponges.
Dry Cleaning
First, brush away any surface dust and filth from the Sandstone using a dry cleaning solvent. Sweep the area carefully with a soft-bristled brush or broom, paying special attention to the edges and nooks. When cleaning the Sandstone, don't scratch or otherwise damage it.
Wet Cleaning
Use a bucket, a tiny amount of pH-neutral cleanser, and warm water as the manufacturer directs. Saturate a sponge or soft cloth with a cleaning solution and squeeze the excess water. Scrub the sandstone surface gently in a circular motion, tackling little parts at a time. You can avoid injury by not pressing too hard.
Getting Rid of Unwanted Stains
Certain methods can be used to remove stains from Sandstone successfully:
- Remove stains from algae, leaves, and mildew using equal parts water and hydrogen peroxide. Using a delicate brush or sponge, remove the stain after applying the solution and waiting a few minutes. Do a thorough rinse with clean water.
- Baking soda and water poultices are effective at removing oil-based stains. The discolouration should be treated with a poultice, plastic wrap, and an overnight wait. Take off the poultice and wash the area thoroughly the next day.
- Commercial rust removers created for natural stone are effective at removing rust spots. Rinse it out well and follow the manufacturer's directions.
Cleansing and Air-Drying
After the Sandstone is washed and dried:
- To ensure that no cleaning product is left behind, give the area a thorough rinsing with clean water.
- To avoid any potential damage or discolouration, rinse away any leftover cleanser.
- Drying the Sandstone with a soft cloth or sponge ensures no moisture is left behind.
Sealing the Sandstone
Consider sealing your Sandstone with an appropriate product to last even longer. Sealing sandstone adds weatherproofing.
For advice on which sealer to use and how to apply it, consult an expert or Sandstone manufacturer.
