Description
CarbonOut Pro is a specialist alkaline poultice designed for the removal of severe atmospheric soiling and deeply embedded carbon deposits from masonry surfaces. It is particularly effective on buildings located in high-pollution areas, where stonework can become heavily blackened and standard cleaning compounds fail to provide results.
In addition to cleaning, CarbonOut Pro can be used as a controlled paint stripper for specific coatings. When applied correctly, it dissolves and lifts multiple layers of paint from masonry without damaging the underlying surface. This makes it a versatile solution for restoration projects involving both heavy soiling and old paintwork.
The paste works by breaking down staining and paint, drawing contaminants out of the masonry and into the poultice. After a dwell time of up to forty-eight hours, the partially dried paste remains flexible and can be carefully lifted away using a corrosion-resistant trowel or spatula. This method not only produces outstanding results but also reduces liquid effluent, as the dissolved solids remain trapped in the paste for easier containment and disposal.
When used correctly, CarbonOut Pro provides a safe, controlled, and highly effective cleaning process that restores masonry to its natural appearance without causing damage or discolouration.
Advantages and Limitations:
CarbonOut Pro offers several important advantages. Its thick paste consistency allows it to cling to vertical surfaces and detailed architectural features, making it suitable for both walls and intricate
mouldings. The formula remains active for up to forty-eight hours, enabling deep penetration into stubborn carbon deposits and long-standing soiling. Because of its dual-purpose design, CarbonOut Pro can also be used to remove multiple layers of certain paints.
By trapping the dissolved paint solids within the semi-dried paste, it significantly reduces the amount of liquid waste typically produced by conventional paint stripping methods. This simplifies disposal and minimises environmental impact.
However, there are some key limitations. CarbonOut Pro contains alkaline ingredients and must be followed by a neutralisation process to prevent damage to the masonry. Without proper neutralisation, residues can remain active and lead to long-term deterioration of the surface.
The product is not suitable for removing paint from metal or wood and should only be used on appropriate masonry substrates. It should also not be applied to glazed or polished surfaces, as this
may cause etching, dullness, or permanent surface damage.
As with all restoration treatments, a pretest is essential to confirm compatibility and to establish the correct dwell time and application method before starting full-scale work.
Preparation:
Thorough preparation is essential for safe and effective use of CarbonOut Pro. Begin by carefully inspecting the work area to identify any surfaces or features that must be protected. Nearby plants,
windows, metalwork, and delicate architectural details should be covered with heavy-duty plastic sheeting or tarpaulins. Secure these coverings firmly to prevent them from shifting during application, particularly in windy conditions.
Before starting, check that both the masonry and surrounding air temperatures are 10°C or above. The product should not be used when temperatures are below freezing or if there is a risk of overnight frost. If freezing conditions have occurred before application, allow adequate time for the masonry to thaw fully before beginning work.
Personal protective equipment (PPE) must be worn throughout the process. This includes chemical-resistant gloves, safety goggles or a face shield, and protective clothing to prevent splashes
from coming into contact with the skin. If you are working in an enclosed or poorly ventilated space, a respirator may also be required to protect against fumes or airborne particles.
If the treatment is being carried out in a public area or where others are present, secure the site using barriers, warning signs, or cones to prevent pedestrians and pets from entering the area while the product is active.
Gather all necessary tools and equipment before starting. This will include corrosion-resistant trowels or spatulas for application and removal, low-pressure rinsing equipment, soft-bristled brushes, and pH testing papers to confirm that neutralisation has been fully achieved.
Pretesting:
Pretesting is a critical step and should never be overlooked. It allows you to confirm that CarbonOut Pro is compatible with the masonry and helps to determine the most effective dwell time and number of applications required for complete cleaning or paint removal.
Choose a small, discreet section of the surface and apply CarbonOut Pro at a thickness of 5–7 mm, using the same technique intended for the full application. Allow the poultice to dwell for 24 to 48
hours, depending on the level of soiling or the number of paint layers to be removed. Once the dwell period has ended, carefully remove the test section using a corrosion-resistant trowel or spatula and rinse the area with fresh water.
For cleaning tests, follow this step by applying NeutraRinse Pro, diluted at a ratio of 1:1 with clean water, to neutralise the surface. Allow the test area to dry completely before inspecting the results. This will help you evaluate whether the process was effective and if any adjustments are needed. This step is especially important for historic or delicate masonry.
Application Process – Cleaning and Paint Stripping:
To begin treatment, use a corrosion-resistant trowel to apply CarbonOut Pro evenly over the target area. The poultice should be spread to a thickness of 5–7 mm, ensuring complete coverage of the soiled or painted masonry.
Allow the product to dwell undisturbed for 24 to 48 hours. This extended period ensures deep penetration and effective breakdown of heavy carbon deposits or multiple paint layers. If the poultice begins to dry and lose flexibility before the end of the dwell time, lightly mist it with clean water and allow it to rest for approximately fifteen minutes. This will soften the paste, making removal
easier and preventing damage to the masonry.
When the dwell period is complete, carefully insert a corrosion-resistant trowel or spatula beneath the poultice and lift it away from the surface. Work systematically, removing as much material as possible. The lifted paste will contain the dissolved staining or paint, allowing for straightforward containment and disposal. If paint remains after the first application, repeat the process until all layers have been successfully removed.
For areas with extremely heavy carbon soiling, multiple treatments may also be necessary to achieve the desired result.
Cleanup and Storage:
After completing the treatment, thoroughly clean all tools and equipment with fresh water. This includes trowels, spatulas, sprayers, and brushes. Cleaning tools immediately after use prevents
product build-up and keeps equipment in good working condition.
Collect and dispose of used poultice material in accordance with local waste management regulations. Do not allow large amounts of product to enter drains or natural water systems. Store CarbonOut Pro and NeutraRinse Pro in their original sealed containers. Keep them in a cool, dry place, away from direct sunlight, excessive heat, or freezing conditions. Proper storage ensures that
the products remain effective and safe to use.
Neutralisation with NeutraRinse Pro:
Following cleaning or paint stripping, it is essential to thoroughly neutralise the treated masonry to prevent damage caused by residual alkalinity.
Begin by rinsing the surface thoroughly with a low-pressure water spray, working systematically to remove all visible residues. Once rinsing is complete, prepare a solution of NeutraRinse Pro, diluted 1:1 with clean water.
Apply the neutralising solution with a soft-bristled brush using gentle scrubbing motions to ensure even coverage. Allow the solution to remain on the surface for 3 to 5 minutes so that it can fully balance the pH levels. After this dwell time, rinse the area again with fresh water, working from the bottom upwards to prevent streaking and ensure complete coverage. Repeat this process as needed until pH testing papers confirm that the masonry has returned to a neutral reading. If the pH remains high, repeat the neutralisation steps until the correct balance is achieved.
Coverage Rates:
The coverage rate of CarbonOut Pro will vary depending on the porosity and texture of the masonry andthe severity of staining or paint build-up. As a general guideline, 0.2 to 0.3 square metres per kilogram can be treated. Highly porous or heavily soiled surfaces may require more product.
