The water-based, non-toxic formula covers worn or stained grout lines, restoring a cleaner, brighter appearance on walls, backsplashes, showers, tubs and floors. Each marker has a cotton 5mm tip for precise application, and the 7mL ink supply covers up to about 150 feet of narrow 2mm grout lines — making the three pens suitable for multiple rooms or a few larger projects.\u003c\/p\u003e\n\n\u003ch3\u003eHow do I get the pen ready for use?\u003c\/h3\u003e\n\u003cp\u003eNew Rainbow Chalk Grout Pens arrive with a dry white tip and must be primed before application. Instead of shaking, rapidly pump the tip onto a scrap surface 30 or more times until ink saturates the cotton; shaking with the cap off can dislodge the tip. If activation feels slow, replace the cap, wait a minute, then continue pumping.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003ePrime by repeatedly pressing the tip down 30+ times until ink flows.\u003c\/li\u003e\n  \u003cli\u003eDo not shake pen without the cap — tip may fall out.\u003c\/li\u003e\n  \u003cli\u003eTest on an inconspicuous area to confirm color and flow.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich surfaces and grout conditions work best with this grout pen?\u003c\/h3\u003e\n\u003cp\u003eUse these pens only on unsealed, absorbent grout; sealed grout won’t bond well. The manufacturer recommends a simple water test: apply a few drops of water — if it soaks in within a minute, the grout is likely unsealed and ready. Avoid applying over silicone or flexible sealants and always test a hidden spot first.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eIdeal for unsealed grout in bathrooms, kitchens, backsplashes, showers and floors.\u003c\/li\u003e\n  \u003cli\u003eNot effective on sealed or non-porous grout — perform a water absorption test.\u003c\/li\u003e\n  \u003cli\u003eAvoid use over caulk, silicone or moving joints.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow long will the color last and how durable is the finish?\u003c\/h3\u003e\n\u003cp\u003eThe formula is a water-based colorant meant to cover stains and restore appearance, not to act as a structural grout repair. With normal use and after proper drying, the recolored grout resists light surface wear, but heavy scrubbing or abrasive cleaners will reduce longevity. For high-traffic floors or wet, frequently scrubbed areas, periodic touch-ups may be needed.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eCovers approximately 150 feet of 2mm grout per pen for thin grout lines.\u003c\/li\u003e\n  \u003cli\u003eBest for cosmetic recoloring; heavy wear areas may require maintenance.\u003c\/li\u003e\n  \u003cli\u003eAllow full drying before exposing to water or cleaners for best durability.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat application tips help get crisp, even lines?\u003c\/h3\u003e\n\u003cp\u003eWork in short, steady strokes following the grout joint, resting the pen lightly to avoid fraying the cotton tip. If the tip wears, pressing too hard will damage it; contact the seller for replacement tip options. Use painter’s tape along tile edges for ultra-clean lines and wipe excess promptly with a damp cloth while wet.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eUse light pressure and smooth, continuous strokes for even coverage.\u003c\/li\u003e\n  \u003cli\u003eProtect tile edges with tape for sharper results and easier cleanup.\u003c\/li\u003e\n  \u003cli\u003eIf the tip degrades, request a replacement rather than pressing harder.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for? Homeowners, renters, DIYers and small contractors who want a quick visual refresh for stained or dingy grout without regrouting will find these pens useful. They suit anyone needing precise control in tight joints — especially in bathrooms and kitchens — and who understands this is a cosmetic recolor for unsealed grout, not a structural repair or permanent sealant replacement.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: How do I activate a new Rainbow Chalk Grout Pen?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Prime the pen by rapidly pressing the cotton tip onto scrap 30+ times until ink saturates; do not shake without the cap to avoid dislodging the tip.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I use the grout pen on sealed grout?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No — test with water: if drops absorb within a minute the grout is likely unsealed and suitable for recoloring.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Rainbow Chalk Markers Limited","offers":[{"title":"Default Title","offer_id":54593780777299,"sku":"B08S7NNYT4","price":45.82,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1095\/4257\/2371\/files\/rainbow-chalk-grout-pen-front-pack.jpg?v=1786779291","url":"https:\/\/findsworth.co.uk\/products\/rainbow-chalk-markers-limited-grout-paint-marker-white-3-pack-5mm-narrow-tip-7ml-water-based-for-unsealed-grout","provider":"Findsworth","version":"1.0","type":"link"}
