What tradespeople mean when they search “cork plaster”?
Most trades searching cork plaster are actually looking for one of these:
Spray cork render for external walls
Cork insulation plaster for internal walls (cold walls, condensation, mould risk)
So the goal isn’t just finding a bucket online. It’s getting the right spec, the right prep, and the right support.
TIWI CorkSpray (VIPEQ® UK): what you’re getting
When you buy through TIWI CorkSpray, you’re not just buying a product name. You’re buying into a system:
Materials supply in the UK
Guidance on substrates, prep and build-ups
Access to training and certification
Sales and marketing support
A network of installers and ongoing peer support
This matters because cork systems live or die on prep, suction control, detailing, and correct application.
TIWI Certified Installer: the new 2026 tier system (explained)
TIWI’s training and installer tiers are built so trades can enter at the right level and then step up as they grow.
The official application page is here:
Tier 1: TIWI Accredited
This is the trade entry tier for businesses who want to add cork plaster to their offer.
You’ll learn the cork plaster system properly (prep, application, and how to sell it to your customer base) and you’ll get TIWI trade pricing.
Tier 2: TIWI Certified Installer
This is the intermediate tier.
It includes everything in Accredited, plus training and access across the full product line, including pre-coloured CorkSpray for external finishes, advanced sales and marketing support.
You’re also backed by private installer support and updates.
Note: Platinum partners get first refusal in their category/domain (where available).
Tier 3: TIWI Certified Installer – Platinum (full range + landing page geographic domain)
This is the business growth tier.
It includes everything in Certified Installer, plus:
First refusal on enquiries in your area
Assets to help you win more work, including a TIWI supported landing page
Stronger positioning for larger domestic and commercial opportunities
Priority assistance, support and enhanced partner benefits
Why a Tier system?
Because not everyone is at the same stage.
Some plasterers want to test the waters and add cork plaster to their services
Some want to go all in and build a cork spray business
Some want leads routed to them and a proper long term growth accelerated plan
A tier system makes it clear what you get, what’s expected, and how you progress.
Who this is for (and who it isn’t)
This is for you if you’re:
A plasterer or renderer wanting to add cork plaster / cork render to your services
A builder who wants a breathable insulation option for awkward jobs
A contractor looking for a system that solves real customer pain (cold walls, condensation, black spot mould around windows)
It’s not for you if you’re:
Looking for a cheap coating with no training, no spec, and no support
Trying to shortcut prep and expect miracles
What people are asking on Google (and what to tell customers)
“Does cork plaster stop mould?”
Cork plaster isn’t a mould killer. What it can do is improve surface temperature at cold spots, which helps reduce the conditions that lead to condensation and black spot mould. Ventilation and humidity control still matter.
“Is cork plaster breathable?”
Breathability is a big reason cork-based coatings are popular. Customers like the idea of a natural, breathable finish that improves comfort.
“Can I use cork plaster on window reveals?”
Yes, reveals and returns are exactly where thin systems shine, because boards can be awkward and create weak points if they’re not detailed properly.
