natural sustainable spray cork

Natural and sustainable

Recommended by Kevin McCloud presenter of TV’s Grand Designs, it offers an eco-friendly and high performance alternative for plasterers and render companies. Cork is taken from the cork oak tree but no trees are felled. Instead the bark is stripped away and this releases oxygen into the air, which reduces carbon dioxide in the environment.

That’s good for the planet. The tree’s bark grows back each time. So it’s a sustainable resource (unlike quarried materials). The raw material goes to make SprayCork.
SprayCork applications
Whether it’s facades, walls, floors or roofs, SprayCork will coat your surface and can to help to solve your problems of thermal insulation, acoustic insulation and damp proofing.

Customer Reviews
Total Trades ConstructionExcellent4.8 Based on 24 reviews fromCallum ListerCallum Lister ★★★★★ Very trustworthy and honest after bad experience with other companies Lee and the team have restored my faith wouldn’t hesitate to call them againPeter ParkinsonPeter Parkinson ★★★★★ I have come across many builders in my life but Total Trades led by Lee are the best. They tackled a difficult job, in poor weather, which included replacing asbestos soil downpipes, excavation for and replacement of damaged drainage, then making good with concrete and tarmac and leaving the site clean and tidy. I know it took a great deal of care and attention to detail to make such an excellent job and I have not seen better workmanship. If ever I need anything else doing their’s will be the number I will call.Peter ParkinsonKevin GloverKevin Glover ★★★★★ Lee and his team have a great product and service. Corksol looks very crisp and fresh. Very easy firm to work with.Steve TowellSteve Towell ★★★★★ Great experience working with Lee and team ,the work has transformed our home ,it’s a fantastic product ,covers a multitude of sins ,would highly recommend.Andrew BardsleyAndrew Bardsley ★★★★★ We found Lee from Total Trades to be very helpful and professional in carrying out the Cork rendering of our property. The job has taken much longer than we had hoped due to the poor weather this year and difficulties with sourcing the Cork render. These were all matters beyond his control but he did keep us informed all the way through. The job was difficult due to proximity to other properties and Lee was excellent in his efforts to complete the work whilst maintaining good relations with our neighbours. We are really happy with the results.Denise BassettDenise Bassett ★★★★★ Lee came out to look at a problem with our kitchen wall. He told us the problem within minutes!! He told us the simple solution 😁. Thankyou Lee for solving our problem and being so honest 😁😁. You certainly know your Trade.Philip CarrPhilip Carr ★★★★★ Lee and his team refurbished our external rendering with Corksol Spray.From the onset Lee was most helpful knowledgable always either answered his telephone or return calls quickly.The work was undertaken and carried out to plan. We are really pleased with the finished result. We would definitely use again for any building work in the future.Chantelle KellyChantelle Kelly ★★★★★ I recently contacted total trades to take a look at our leaking flat roof (3 in total), the company was highly professional from the very first point of contact. It soon became apparent that our roof was in a bad condition, and the previous roofer had done a really bad job using shed felt, and poor workmanship. Total trades provided us with a quote for a new GRP roof and trims, and we got booked in quickly for the work to be carried out. On the day, the team was fantastic. They arrived on time, was friendly and polite, took their boots off when indoors, and tidied up at the end of each day. Once the job was complete, they took away all the old felt and timber to dispose of, and left us with a brand new watertight roof with a 20 year guarantee. We are extremely pleased with the whole process, from first point of contact all the way through to completion, and would highly recommend Total Trades to everyone. They set a perfect example of how companies should operate, and have left us with total peace of mind. Thank you for such an amazing service.js_loader

SprayCork FAQ's

Does SprayCork have a smooth finish?

No, it is a textured finish. It’s slightly stippled, and it is the granulation of the cork which gives it its performance.

What is the application process?

The application process is the same for internal and external applications. As long as you have a clean dry surface the SprayCork will adhere to any substrate except pure silicon. The product is a sprayed application either sprayed by a gravity fed hopper gun or a spray machine which can spray with a 6mm nozzle (airless does not work). Two coats need to be sprayed to build the product up to a thickness 3-4mm. For internal works the SprayCork can be skimmed/plastered directly onto with no primer/PVA please note drying times are significantly slower and Multi-finish, Board-finish and airless plasterers all work.

Is SprayCork a better insulator on the inside or the outside of my house?

This is a great question and one to definitely consider when upgrading your property. SprayCork can be sprayed internally then skimmed/plastered over to create TIWI (Thin Internal Wall Insulation) at only 8mm including smooth finish and paint. Alternately SprayCork can applied externally on your home/building to refresh and dramatically improve the appearance, as well as offering a multitude of benefits. Either option gives flexibility, breathability, thermal and acoustic insulation, mould and condensation elimination and fire resistance. The performance remains the same. Both options have been tested to ISO9869 and offer around 30% energy savings on heat transfer through walls. Internal application is advisable for dealing with condensation or black spot mould and is particularly useful in heritage buildings or areas where external application isn’t possible.

Can it go over my existing render?

Yes, it is possible to go over existing renders and other substrates and still get a 25-year product warranty. However, just to manage expectations, SprayCork will not hold your wall together so any blown or shot render will need to be rectified first. For example, if you have sand and cement render which is painted and has hairline or settlement cracks, as long as the substrate is solid you can go direct onto the render.

How many colours does SprayCork have to choose from?

We have a standard colour range with 28 fade resistant colours. We also have a colour pigment machine in house which can make up to 1800 colours so if you have a specific RAL code we can make this colour (min order required 300m2 or development cost on smaller orders) for any commercial property orders.
