You Will Need:

Removing Cement from Patio Flags

Step 1

Start by using a garden hose to wet the area you are working with, ensure the whole area is wet.

Step 2

Make sure you are wearing safety goggles and long rubber gloves when you are dealing with acids.

Fill a clean bucket with 4.5 Litres of Water.

Pour 1 cup of Hydrochloric Acid 10% into the bucket of Water.

** PLEASE NOTE: NEVER POUR WATER INTO ACID – ALWAYS POUR ACID INTO WATER AS THIS CAN CAUSE A BUBBLE REACTION THAT COULD SPLASH OUT OF THE BUCKET**

Step 3

Start by using a stiff-bristled brush and brush the diluted acid solution onto the patio.

Step 4

Allow the solution to sit for a short amount of time.

Don’t worry if you start to see a bubble reaction as this means it is working!

Step 5

Using the same brush, start scrubbing the cement as quickly as possible from the patio. (this needs to be straight away to stop any remaining acid being on the patio)

Step 6

Once you have scrubbed the cement off and all the acid has been removed, make sure you thoroughly rinse the patio with clean water.

** Please note if this doesn’t remove the cement, the solution may not be strong enough, in this case repeat however using a stronger solution: 1 part hydrochloric acid to 10 parts water**

Removing Cement from the Mixer

You Will Need:

Hydrochloric Acid 10%

Water

Googles

Rubber Gloves (acid resistant)

Bucket

Step 1

Start by turning the mixer on and allowing it to spin.

Step 2

Ensure you are wearing your protective gloves and goggles.

Step 3

In a bucket pour one part Acid into two parts of water.

** PLEASE NOTE: NEVER POUR WATER INTO ACID – ALWAYS POUR ACID INTO WATER AS THIS CAN CAUSE A BUBBLE REACTION THAT COULD SPLASH OUT OF THE BUCKET**

Step 4

Once the solution has been mixed, pour into the barrel and keep the mixer spinning. The acid should remove the final layers of cement. Make sure the mixture reaches the edges of the barrel.

Step 5

Drain and dispose of the acid correctly.

Step 6

Using a hose pipe, rinse the drum with the water and allow the mixer to dry.

Removing Cement from Hand Tools

Step 1

Fill a five galloon bucket with 3 galloons of tap water and add two cups of Hydrochloric Acid 10% to the water. Stir with an appropriate tool until mixed.

Step 2

Taking caution add the metallic part of the tool to the acid solution and watch as the cement starts to come off. Allow it to soak whilst staying with the tool.

This will give you a good indication when to take the tool out based on the size of the tool and amount of cement.

Step 3

Thoroughly wash away the residue and scrub at the same time, the tool may need to repeat the steps to get it all off.

Once done, rinse with water and allow to dry.

Dispose of the acid solution correctly.
