Limestone, even a few years back were luxurious. Limestone floors and shower counters weren’t that easy to find.
Even though it’s still true to some extent, limestone counters and flooring are creeping slowly into the houses of the average consumer. It’s becoming a commodity rather than a luxury.
And that’s where the problem starts.
Alluvial rocks like limestone are dependable in terms of long-term usability. Still, it’s not impervious to getting attacked by grimes and streaks. Scratching and etching are two of the common things that may ruin the beauty of your sleek looking limestone surfaces.
And that’s where you’d need to think about pressure washing limestone.
Pressure washing a limestone surface implies that it’s been exposed to some tough scratching (it’s nothing unusual of course). The tough streaks will get washed away easily once it’s exposed to pressure washing.
So, let’s not waste any more time and start washing limestone!
Power Washing Vs. Pressure Washing
There are two distinct terms when it comes to dealing with tough stains and grimes. The argument entitled ‘power washing vs pressure washing’ reveals very little dissimilarities, but major ones.
For example, power washing is done with a strong hot water jet. A strong stream of hot water gets blasted on the surface that requires cleaning.
The strong flow of water and high temperatures can tackle mold build-up, annoying grunge, and even foreign residue.
But if you think of the integrity of the surface, then you’ll find that power washing may cause more harm than good in some cases. And that’s where pressure washing comes in.
Pressure washing has the same principle. But it uses a regular water stream instead of a hot one.
It’s still very effective in the right scenarios. And there are no major safety concerns because of the regular water temperature. And that’s the very reason for pressure washing to be highly suitable for cleaning limestone surfaces.
Pressure Washing Limestone: The approach
Here are a few simple steps to get you started with pressure washing. Do keep in mind that the steps we’re about to show you can be tailored to your needs. Still, the basics need to kept the same.
Identify the surface
The first thing you should do is find out the surface that needs cleaning.
But there’s a catch. Decorative limestone surfaces may not bode well with pressure washing.
Though pressure washing is highly recommended for tough grimes and streaks, there may be unwanted results when applied on limestone flooring with decorations.
The first step is more of a precautionary measure that needs proper attention.
Prepare the pressure washer
Make sure the hose is not clogged with any sort of foreign debris. Keeping your hose in proper working condition is a priority in this case. Otherwise, the results may not be as fruitful as you’d want.
Run the pressure washer over the infected surface
You may want to think of step 3 as the main step of the entire operation.
Run the pressure washer over the grimes of the limestone surface. Our recommendation would imply that you do not use full pressure. Setting the unloader valve to a suitable position is of utmost importance in this case.
For regular users, using the pressure washer somewhere from 1300 to 2300 PSI should be enough. But try and keep the pressure setting as low as possible. That’s both safe and efficient.
Apply a suitable cleaner
Use natural cleaners for such purposes.
Strong chemical agents can harm the integrity of the limestone surface. So, going with a natural solution is your best bet. Otherwise, you may find unwanted streaks or etching on your limestone exterior.
In case you go for a commercial cleaner anyway, beware of the debates going on comparing different commercial cleaners in the market.
Use a soft-bristle brush for cleaning
Up to this step, you’ll find that the grunge is now easily removable. Use a soft-bristle brush to remove grimes from the limestone. You don’t need to use any excessive force in this case.
Give a final rinse
A final rinse using the pressure washer should clean the surface entirely. It should bring back the beauty of the limestone to its full potential.
And that’s all there is to it.
A word of advice- don’t start working on a large surface at once. If you don’t let the surface dry properly, then there is a possibility of unwanted streak formation. And after so much hard work, you wouldn’t want that to happen, would you?
A simple solution is to dry out the surface with a fine thread towel. This will ensure that no streaks are formed.
There’s no harm in being clean and tidy, especially when you go the extra mile to get limestone flooring or a counter-top.
Delicacy is a requirement to keep such aristocracies in check. And we do hope the steps we’ve shown you will help you out.
