Ideal for bathrooms, kitchens, and floors, it delivers a fresh, uniform look with easy application and excellent coverage. ## Description Product Description Grout Magic is a colourant that is similar, but much more effective to grout paint. The best solution for restoring wall & floor grout from old & run down to brand new! Grout Magic can totally change the colour of grout when required. It is the perfect grout restorer. Application Guidelines Ensure the area is clean & dry. Shake Grout Magic vigourously before use. Apply in a thin coat over the grouted joint using a brush or sponge & apply evenly over the surface. Wipe off any excess that is on the tile within 5 - 10 mins (see below). Best results are acheived when two coats should be applied, allow 1-2 hours drying time for each coat. Do not wet the area for a further 48 hours. Smartseal Grout Magic How does Grout Magic work? Grout Magic is an effective grout dye that restores or changes the colour of tile grout. Another benefit is that it acts as a sealer that penetrates deeply into the grout. It will dramatically enhance the appearance of any wall or floor tile. Once applied & fully cured, Grout Magic will enhance the grout, by giving it a long-lasting protective seal. It will also inhibit the growth of mould & mildew on the tile grout. Grout Magic is a premium high-quality alternative to the Grout Pen. BENEFITS RESTORERS & SEALS GROUT IN ONE GO TURNS OLD GROUT BRAND NEW REMOVES GROUT STAINS 10 COLOURS TO CHOOSE FROM - SAMPLES AVAILABLE NOTE: It is essential to complete a test patch to determine how long the product can be left on the surrounding tiles. Depending on the type of tile, you may need to remove the product excess within 5-10 minutes or it may be possible to leave up to 30 minutes – note, if left too long it will be extremely difficult to remove. For best results, we recommend a two-stage process Stage 1: Prime the grout surface area on both old and new installations with Grout Magic Pre‑Treatment. Stage 2: Apply Grout Magic Colour & Seal when the grout joints are clean and thoroughly dry. Shake bottle & mix well before use. If using more than 1 bottle of a single colour for an application, mix all material to ensure colour match and consistency. Make sure the grout joint is clean and thoroughly dry before applying Grout Magic Gently squeeze the bottle to apply steadily and consistently onto the grout joint using your preferred application tool, eg a small, stiff brush or sponge working it evenly onto the grout surface. Wipe away any excess sealer from the tile surface within the timeframe established from project test (as a guide, within 30 minutes or less). Work in small manageable areas whilst applying and cleaning down – your test patch will dictate when to halt application to remove excess. Allow 48 hours drying time before wetting (using shower room) or cleaning the treated grout area. Poor application, applying the grout colourant too heavily or thickly onto the grout joint can result in blistering, cracking and de-bonding of the colour sealer. This product is not recommended for use around porous surfaces i.e. unglazed tiles and natural stone surfaces as it could permanently stain. FOR INTERNAL USE ONLY. PLEASE NOTE If application guidelines are not adhered to, this could result in cracking or peeling of the product. After using the sample, if you decide to fully apply ‘Grout Magic’ we recommend using ‘Grout Magic Pre-treatment cleaner’ this ensures the product bonds correctly. ## Features - Restore, Recolour and Protect Your Grout - Grout Magic is a professional-grade grout restorer designed to rejuvenate discoloured or stained grout lines.
