Grout Rescue X (450ml)

Specialist Outdoor Grout Colourant, Renew, Sealer & Dye


We strongly recommend that you prime the surface with Grout Rescue X Pre-Treat Cleaner before application for optimum results and maximum longevity, whether the grout or pointing is new or old.

About colour…about colours...

The colour chart must be used as a guide only; due to the original grout colour, texture, grout width, artificial and natural lighting the finished Grout Rescue X colour may dry slightly different once applied – as an example, applying a grey grout to white tiles will make the grout look darker due to the contrast of light and dark, whereas if you apply mid grey grout colouring to pure black tiled surfaces, then the grey grout will look lighter in contrast to its surroundings.

Grout Rescue X Colour Sealer Swatches

Our policy is that we cannot guarantee an exact 100% match and you should chose a grout colour that MOST CLOSELY MATCHES the colour scheme you want to achieve. Always do a small on-site test in an inconspicuous area so you can assess the results BEFORE undertaking the grout rescue X colour seal process.

Grout Rescue Colour & Seal
If you are looking to change the colour or renew your internal grout, you should consider our market-leading colourant sealing formula, Grout Rescue Colour & Seal. Designed to renew and protect internal grouting, it is ideal for bathrooms, kitchens, tiled floors and more (10 colours).

Directions for use

NOTE: Due to our improved formula’s high polymer strength, you must complete a test patch to determine how long the product can be left on the surrounding tiles / slabs / pavers. Depending on the type of tile, you may need to remove the product excess within 5-10 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 or pointing area on both old and new installations with Grout Rescue X Pre‑Treat Cleaner.
Stage 2: Apply Grout Rescue X Colour Sealer when the pointing / grout joints are clean and thoroughly dry.

  1. Stage 1: Using Grout Rescue X Pre-treat Cleaner is very important to achieve perfect results prior to application of Grout Rescue X Colour Sealer. Prime (etch) the grout surface area by thoroughly cleaning grime, debris and algae/lichen with the Pre-treat cleaner as per its instructions.
  2. Stage 2: Make sure grout joints are clean and thoroughly dry before applying Grout Rescue X outdoor grout sealer. Shake bottle & mix well before use, always a complete a small test patch to understand best process of application.
  3. Apply product thinly onto the grout joint using a small paint or tooth brush, working it evenly onto the grout surface. Wipe away any sealer with a damp cloth or sponge from the tile edge instantly or within a maximum of 10 minutes of application, being careful not to disturb the treated grout joint. Dries within 1-2 hours, and achieves full cure within 48-72 hours. Avoid unnecessary use or footfall during this time period. If using more than 1 bottle of a single colour for an application, mix all materials to ensure colour match and consistency.

Poor application, applying the product too heavily or thickly onto the grout joint can result in blistering, cracking and de-bonding.
Always perform a small inconspicuous test on-site to determine suitable application process for your project. Call our support helpline on +44 (0)1300 345 898 (option 2) or use the contact form on our website for technical support. FOR EXTERNAL USE ONLY.

Grout Rescue X Colour Sealer Swatches

To avoid disappointment, please note: We do not manufacture sample bottles or provide smaller sizes. The swatches provide a near match to the actual product, however, as you may expect, screen displays and print processes cannot match the colours 100% accurately, so if colour matching is crucial, we recommend you find a stockist and see the product colours in store. We will not be responsible for any colour matching problems as it remains the final responsibility of the user to confirm colour suitability.
