Stone Retaining Walls – How to Clean Them

Some citizens do not recognize whether a ‘premise’ is on their land with an old stone retaining wall. It can be maintained or ‘removed’ instead of seeing this piece of history slip into disrepair! A proper purification of an old stone retaining wall will restore the wall and again render the yard and the landscape magnificent.

You must be clean, mean! –

Old stone walls are built of years of soot and mould. Depending on the extent of the mould and soot, these stains may be challenging to clean. Fungal and algal development can also occur, as well as vines or earth cover the root in the wall. Then what do I do? Ok, you know these parasites must go! But let’s pull out the washer and get ready to vacuum!

Using a press washer of medium size –

is the press washer ready? All right, fine… Now… Now… STOP!! STOP!! At this point, the worse thing you can do is start the pressurized washer and blow out both joints with a high pressurized spray!

 

Furthermore, if you start washing the wall without the right soaking, you can just push the sugar deeper into the pores of the walls by wicking… Keep your horses! Hold your horses! No… No… A bit more nuanced and smoother is the way I would clarify to you.

 

Okay. Okay. Begin the cleaning process by saturating the wall first. This is done by wiping the wall gently with a wide angle soil. Only stand back from the wall, maybe 3′-4′ and flow across the water and stream down the wall.

 

Your wall is already fully soaked, enabling the detergent to pierce the wall system deeper and lift the soot and grime away. A saturated wall often stops the detergent from drying up prematurely, ensuring that it has enough time to fulfill its purpose.

 

The key is to use an industrial quality degreaser –

a targeted order of a heavy degrader from a firm with commercial pressurization now occurs. Do not dilute. Do not dilute. Put the detergent straight into a garden sprayer from the bucket and start spraying the wall. Make sure every inch of the wall is protected and you strive to preserve a “wet look.” This degrader costs a couple of dollars but it isn’t the scrimp spot. Purchase the degreaser if you want the washed wall… simple. simple.

It seems worse now!

– All right, the wall has already been saturated and the degreaser is being added, but what are you doing? You’re wondering. That’s correct… That’s right… You just watch. You wait.

 

The wall begins to transform dark amber and a dirty brown after about 10-15 minutes. You’re likely to see lines of grime streaming down the stone. The wall looks bad and you’re afraid you’re screwing it! That’s fine. That’s good. When you feel like it is a lost cause and are about to throw in the towel, you will realize that your job is nearly over!

 

Now that the degrader has got an ability to function through removing the dungeon, it is time to stir it like a washing machine. The usage of your 15-degree punch starts to strike the wall rapidly and randomly from top to bottom. This time you don’t want to saturate the wall. When you see the soap suds coming from the spray pressure, step up and down the wall and continue along its length.

 

You should do so a number of times around the wall to allow the deepest possible washing. This excitement dilutes the degrading agent to a lower viscosity and creates soap bubbles that expel the surface soot and shrink.

 

Okay, all right… You can blast it out! Now you should push it out! – You will now continue to the last stage of washing the wall after the degreaser has been agitated. You placed the wall about 12″ – 16″ apart from the face of the wall from where you first sprayed the degreaser.

 

Through seeing the soot rise from the wall, you sweep up while you transfer the dust from joint to joint, and from stone to stone. You can see the soot and the dreadful raise as you step down the wall. If a segment is drying out too soon, agitate again to hold it moist before you hit the section.

 

You’ll be shocked how fast soot, grime, mold and dirt have been washed off for years. Stubborn stain areas can need further application.

 

When you finish, you’re in astonishment! The old wall looks clean and refreshed and your work is done. After all this hard work, sit back and admire the elegance of your renovated wall… You deserve to rest after all!
