It is also important to know the exact coverage that your High Pressure Brickwork Cleaning insurance policy covers. There are a number of different policies that can be offered, so it is important that you find out exactly what is covered and how much is covered. Some policies will cover the cost of having a claim covered, while other polices will include the cost of the removal of any covered items. If you need to have certain items removed, you will need to work out how much those items cost before you contact your professional broker for a quote.
When it comes to brickwork, there are three main methods for cleaning the brickwork. The first method of cleaning is called high pressure cleaning or HPR. The HPR method is widely used as the professional cleaner can safely stand on the floor and even if he is using extension tubes to the wand he can still clean the brickwork without any risk of falling off the floor. Getting the brickwork wet is also one of the key aspects of brickwork cleaning.
High pressure cleaning or HPR requires scrubbing the brickwork with abrasive blasting head. After every cleaning the brickwork with the HPR machine is washed with water and dried completely. However, there is one problem with the above mentioned method of HPR. The water used for washing the brickwork leaves some residue on the bricks which makes them loose their original colour. Hence, it is recommended not to use HPR when you re-vese your brickwork.
Another method of brickwork cleaning is done by spraying a mixture of water and detergent onto the surface of the brickworks. However, the surfaces to be cleaned should be well pre-cleaned before using the compressed air. This will ensure that no dirt particles will be left behind after the spraying of the mixture. In case, if the bricks are already very dirty then use of water is highly advisable.
It is again another important aspect of brickwork cleaning which should be taken into consideration. Brick moss is a type of fungus that forms on the flat surfaces of the bricks. Without proper care the molds can cause considerable damage to the structure of the brickwork. The damaged areas can easily succumb to wood decay and/or damage due to heat. In such scenarios, damage control through the application of pressure on the molds is the only method of dealing with the moss problem.
For special cases like the brickwork cleaning of old Roman structures, blasting is the only option available. In blast application, a highly pressurized stream of compressed air is directed at the brickwork surface. This process should only be performed by trained professionals, as the resulting damage can be extensive. Moreover, blasting is a major safety hazard and thus it should only be performed by competent professionals.
Muriatic acid is another chemical solution often used in brickwork cleaning process. This chemical has the property to break the bonds between the grout and the concrete surface. Once the grout is dissolved by the acid, the concrete sealant or sealer is removed through a draining hose. Once the chemical is removed from the surface, this slurry can be easily scrubbed or rinsed with warm water.
Brickmould removal using hot water is another common brick cleaning method. In this method, hot water is pumped at high pressure through an ultra-hot water pump in order to loosen the tough dirt on the surface of the bricks. However, this method is often very hard and time-consuming. Moreover, the intense heat can cause damage to some delicate parts of the bricks.
Other than these methods, there are specialized cleaners that can also remove dirt and soil from concrete, slate, marble and granite surfaces. These cleaners can be applied using rotary brushes, roller brushes, power scrapers and other rotating tools. These tools have the ability to penetrate into small crevices that may not be reached by abrasive tools.
Besides brick cleaning, another important brick cleaning method is software. This technique is used to remove dirt and stains from concrete surfaces, brickwork and slate. Softwash is the best option for marble and granite surfaces, as it does not cause any damage to these surfaces. This type of cleaning solution is generally made of water, biodegradable chemicals and sodium hydroxide, which is a naturally occurring compound found in soap. This ingredient is mixed with the cleaning solution and then sprayed onto the surfaces being cleaned.
Some of the common ingredients of softwares used for brickwork cleaning include sodium hypochlorite, calcium thioglycolate, calcium carbonate and magnesium thioglycolate. These ingredients are mixed together and sprayed onto the stained areas. The frequency of use and the duration of treatment vary according to the requirements of the project. For removing light stains, such as red wine stains, household cleaning products, oil based paints and grease, mildew or other organic stains, this technique is considered to be very effective. Some of the other types of cleaners which can also be used for cleaning masonry surfaces include acid cleaners, alkaline cleaners, biocides, hydrochloric acid, hydrogen peroxide and most commonly, abrasive blasting. Abrasive blasting is an extremely aggressive form of brick cleaner and is ideal for removing deeply ingrained and badly stained bricks.
For Brickwork Cleaning using low pressure washing systems is a recommended method. This technique is ideal for removing stains, grease, dirt, oil, smoke and grease from brick walls and floors. Low pressure washing systems use water jets which are directed at the dirt or stain and they are absorbed by the material they hit, rather than being scrubbed away.
