Colour Fast Technology
The innovative colour fast technology has been specially designed to resist the bleaching effects of the sun, ensuring the rich original colour stays for longer.
Larsen's Colourfast 360 Flexible Patio Grout is ideal for use with our range of porcelain paving.

Use the Larsen Colourfast 360 patio grout as a value-for-money choice for all types of paving, wall and floor tiles, internally and externally. This patio grout mix is water-resistant, so can be used in fully immersed conditions, such as swimming pools where cementitious grouts are recommended.
Technical properties
With enhanced flexibility, Larsen's Colourfast 360 Flexible Patio Grout is available in a choice of six colours and is suitable for a wide range of joint widths from a slender 1mm, perfect for porcelain and other contemporary paving types, up to as wide as15mm. The non shrink nature of Larsen Colour Fast also ensures that the grout will reman intact for long periods of time, especially important in high traffic outdoor areas that are exposed to high levels of moisture and fluctuating temperatures. It's workable for approximately 30-40 minutes, depending on conditions, and is ready for light foot traffic after about three hours.
Do I need to grout paving slabs?
The short answer is yes. Butt-jointing is sometimes suggested—where slabs are laid edge to edge. This will only lead to tears because contraction and expansion will cause slabs to shift slightly, resulting in damage to the edges. Grout is there to act as a flexible cushion, stopping excess water from penetrating between the slabs, compromising the mortar bed, and allowing movement between slabs.
Should I seal paving before I grout it?
Not all paving requires sealing, though you may choose to seal anyway, in order to help with cleaning. We generally recommend that porcelain doesn't need sealing. Higher density, less porous natural stone such as granite and riven sandstone doesn't absorb dirt easily and may be left unsealed, but it's our recommendation that sawn paving is always sealed. Paving is best sealed before laying as this means it can be kept undercover, clean, and dry while the sealant is applied. If the paving has already been laid, we recommend sealing before grouting. Find more information about when paving should be sealed.
Maintaining your grout
For general maintenance, the grout lines can be cleaned using warm water and a mild PH neutral soap. We don't recommend using hard abrasive tools, or power washing as both could damage the surface of the grout. For tougher stains like, oil, grease or algae, chemical cleaning agents may be required. We always recommend taking professional advice before using chemicals. If you need help with this, get in touch with a member of our team.
