It suits narrow joints from 3mm.<\/p>\n<p>If you&#8217;re laying or restoring a patio, the joints make or break the finish. Ordinary cement and brush-in grouts crack, stain and let weeds back through within a season or two. <a href=\"https:\/\/youtube.com\/shorts\/uPIH8gPz7Fo\">GftK vdw 815+ is the fix.<\/a><\/p>\n<p>It&#8217;s a professional epoxy grout for porcelain slabs and fine natural stone with joints from 3mm. As a result, you get clean, tough, weed-free joints that still look good years later.<\/p>\n<p>So from garden patios and pool surrounds to commercial terraces, it&#8217;s the porcelain paving grout the professionals reach for. It also works for grouting and repointing flexible paving with unbound stone setts.<\/p>\n<h2>Why vdw 815+ is the porcelain paving grout professionals choose<\/h2>\n<ul>\n<li>Less time on your knees. It&#8217;s poured and squeegeed in as a self-compacting slurry, with no slow hand-pointing.<\/li>\n<li>No weather delays. Because it goes on pre-wetted slabs, you can grout in the wet \u2014 even in light rain, down to +3\u00b0C.<\/li>\n<li>Stays looking clean. It&#8217;s non-staining on porcelain and sensitive stones like sandstone. Also, you can jet-wash it as often as you like.<\/li>\n<li>Built to last. It&#8217;s tough, abrasion-resistant, and fully frost- and de-icing-salt resistant. Plus it keeps weeds out for good.<\/li>\n<li>Safer and more sustainable. The joint is smooth, uniform and durable, so it reduces trip hazards.<\/li>\n<\/ul>\n<h2>Where to use GftK vdw 815+<\/h2>\n<ul>\n<li>External porcelain paving on patios, terraces and pathways<\/li>\n<li>Natural stone, including sensitive Indian sandstone and coloured limestones<\/li>\n<li>Pool surrounds, commercial and retail paved areas<\/li>\n<li>Repointing stone paving with narrow joints<\/li>\n<li>Domestic driveways and other light-to-medium-traffic areas<\/li>\n<li>Refurbishing and repointing flexible unbound stone paving to prevent weed growth<\/li>\n<\/ul>\n<h2>Why epoxy is the best grout for porcelain paving<\/h2>\n<p>Outdoor porcelain is dense and non-absorbent. So cement-based grouts struggle to bond, and they often crack or lift.<\/p>\n<p>A 2-part epoxy like vdw 815+ bonds chemically instead. It also copes with temperature changes, so the joint stays put for years.<\/p>\n<p>Applied as a wet slurry, it fills even tight 3mm joints completely, with no gaps for water or weeds. For wider joints from 5mm, or areas taking vehicles, use our <a href=\"\/Shop\/product\/gftk-vdw-850-paving-joint-mortar\/\">GftK vdw 850+<\/a>.

Then mix the resin-coated sand with the hardener.<\/p>\n<p>Pour it onto the wet surface. Then use a squeegee and more water to move it as a slurry into the joints, where it self-compacts.<\/p>\n<p>No extra tooling is needed. Finally, rinse and brush off any excess with a fine spray and a soft coconut brush. This leaves the surfaces clean and the joints neatly finished.<\/p>\n<p><a href=\"https:\/\/www.nccstreetscape.co.uk\/paving-jointing\/vdw-815plus.html\">Full product info &amp; downloads<\/a><\/p>\n<h2>Colours, sizes &amp; fast UK delivery<\/h2>\n<p>GftK vdw 815+ comes in three colours: Natural, Stone Grey and Basalt.
