☀️ Important Update for all our Restoration & Heritage Clients! ☀️
With this current heatwave sweeping across the UK (30°C+ in many areas – stay hydrated out there!), we wanted to remind everyone about Steadfast SPL Lime Restoration Mortars (like our popular Tough Stone range).
These high-quality hydraulic lime repair mortars are fantastic for stone and masonry restoration – breathable, flexible, and perfect for matching historic buildings. But right now… it’s simply too hot to apply lime mortar properly.
Why wait?
• High temperatures cause the mortar to dry and set way too quickly.
• This leads to cracking, poor adhesion, and weakened repairs.
• Best practice is to avoid applying lime products above 20/30°C.
We’re advising all tradespeople and DIY restorers to hold off on external lime work until we get some cooler days. Plan your jobs for early mornings or wait for the heat to ease – your project will thank you for it!
Steadfast SPL Lime Restoration Mortars are still the go-to choice for tough, long-lasting repairs when conditions are right. Stock available now – just time your application wisely.
