The first is to use a solution made up from vinegar and water — in equal parts. Vinegar will not only get rid of the mould but it should also help eliminate or at the very least fade out, the stains. Use a spray bottle to apply the solution, allow it to sit for a couple of hours, then wipe the area down with a damp cloth or rag. Spraying is the ideal method of application. Use a Mesto sprayer that flows approximately 1 gallon per minute (suitable sprayers available from the accessories section below). Speed//STRIKE may also be applied by roller coating,mopping or brushing. A thin film should be applied for maximum economy and efficiency. Runs or puddles need to be brushed out. For metal forms, the best results are obtained with a spray-on 'fog' application of Speed//STRIKE. Coverage
Mould is dangerous and can cause all kinds of health issues, from skin rashes to breathing problems. For this reason, when removing mould spores from wood, protect yourself by wearing a mask, eye goggles and long-sleeved clothing —if you have protective clothing you could put on over your usual clothing it will be even better. You should also wear rubber gloves.CMT Group ensures that you, our valued customer, enjoys your shopping experience as we strive to make your experience ‘hassle free’. THORCAST mould release oil in manufacturer’s sealed drums requires no special storage facilities. Product is not flammable
To avoid contamination of the reinforcement, it is advised that the shuttering oil is applied on the formwork before it is erected. Mould oils play an essential role in enabling efficient production processes, enhancing product quality, and extending the life of moulds in diverse industries such as manufacturing, construction, automotive, and plastics. What mould oils can you supply? You can often tell whether or not the mould has got into the wood as stains tend to linger even after trying the soap and water method. THORCAST Mould Oil is a formulated blend of mineral oils with additives and a degree of surfactant designed to work as a concrete release oil for demoulding concrete from all types of formwork moulds. It can be used on a wide range of metal, proprietary timber, ply and other formwork materials and coatings, however if using on plastic or rubber moulds consideration should be given to using our Norsekem Teknistrip. Formulated to give optimum release and quality of finish to concrete over a wide range of mix designs. Product is low hazard and not labelled as flammable.If the wood in question has not been painted or varnished, you might need to take a different approach. This is because you need your cleaning solution to penetrate the wood to eliminate any spores that have permeated the timber.
The performance of shuttering oil is largely dependent on the type of formwork that is being used. For wooden formwork, straight refined, pale, paraffin-based mineral oil and oil-phase emulsion have been successfully used. The oil that is chosen should be capable of penetrating the wood to some extent while leaving the surface slightly greasy to touch. The main purpose of mould oils is to make it easier and cleaner to release the finished product from the mould, while also maintaining the integrity of the mould. Here are some key points about mould oils: Clean all form surfaces thoroughly prior to application. Remove all rust, scale and/or previously used form release agents from the forms, in accordance with good concrete practices. It is imperative when using new timber forms of all types (plain wooden, plywood, rough cut etc.) that Speed//STRIKE be applied and reapplied until complete saturation has been accomplished prior to first use. Application However, before any mould problems can be fully resolved, it is vital to understand what causes dampso you can work out where the problem is originating. Damp and condensation are both prime causes of mould on all kinds of areas of the house, from walls and ceilings to wooden furniture and even fabrics such as curtains.
Once the concrete is set, the shuttering is removed and the process repeated.The use of mould oil also extends the life of your road forms and concrete shuttering, protecting equipment from concrete build up, and ensuring strong and accurate edges and easy formwork release. There are several types of natural cleaning solutions that can work to remove mould from wood. Some are more suitable for painted wooden surfaces, such mould on skirting boards or window frames, while others are best for bare wood. Effects a clean positive release, which reduces labour costs, cleaning time and possible damage to formwork. There should not be any free oil on the wood surface. The form release agents that are good for wooden formwork are not always suitable for steel formwork. And hence the shuttering oil or form release agents should be chosen based on the type of formwork that is to be used for construction. Applying mould oils is a flexible process that can be accomplished through various methods such as spraying, brushing, or wiping onto the mould surface. The choice of application method depends on factors like mould type, accessibility, and the consistency of the oil being used.
In the case of wooden formwork, shuttering oil prevents water absorption from concrete by the wooden formwork. Many new forms are not factory treated with oils, so for new or ‘unsealed’ timber formwork, pre-treatment is essential with two to three coats prior to use. This will extend the useful life of the form and help to standardise surface absorbency. For unsealed ply consideration could also be given to primary sealing with NORSEKEM SHUTTAWAX or NORSEKEM FORMSEAL PU1K sealer This stuff worked a treat," says Amy. "I had an old bottle lying around and sprayed it on. I waited just over five minutes and wiped and off it came. I was actually pleasantly surprised how easily it came off. Note, it did leave a bit of a chlorine smell like a swimming pool, which I didn't mind as it made the bathroom smell clean but it might bother some." What causes mould to grow on wood?Our Mould Oil helps ensure that formwork remains free of concrete deposits is therefore an essential task and an efficient and powerful cleaning agent is a vital product to get the job done.
