    Thank you for your review, and we're sorry to hear the colour wasn’t quite what you expected. Limestone can vary widely in nature, from pale greys and creams to warm beiges and honey tones. Our Limestone shade is a warm beige, created using natural ground stone. To help avoid any disappointment, we always encourage customers to order a sample pot or hand-painted colour chart before placing a larger order. We know our paints are an investment, which is why we highlight this throughout our website. If we can help you find a shade that’s more in line with what you had in mind, we’d be glad to assist. Kind regards, The Stonelux Customer Care Team

    Cement paint

    I used this paint for my garden statues, which gave me superb results It just took a bit of effort in preparing the ornaments before painting such as washing them down

    Does exactly what it says

    I used the primer and followed instructions to apply three coats. I'm over the moon with thr final result. The customer service, delivery, and product itself are fantastic.
