From: £25.00

Showerguard™ Easy Clean Coating is a fluorine free surface treatment for new and existing shower installations, that creates a surface that facilitates beading and dirt repellent performance. It prevents limescale and soap scum build-up, making glass and other non-absorbent surfaces ‘easy clean’.

An easy to use home application kit for bathroom and other household surfaces.

Coverage 30ml covers approximately 3m2


Showerguard™ Easy Clean Coating for new and existing shower installations, provides protection for shower enclosure glass, glazed ceramic titles porcelain and mirrors. Easy maintenance for new and existing bathroom furniture with the strongest and most durable glass improvement system available.

The nano-particles within Showerguard™  form a strong bond with the surface of the glass, glazed ceramic tiles, porcelain and mirrors giving them a smooth anti-stain, non dis-colouring surface layer.

The coating is crystal clear, UV stable, chemically inert and extremely durable, having both hydrophobic and oleophobic capabilities providing a robust defence against the build-up of limescale, soap residues and urine scale. Cleaning frequency can be reduced by as much as 70%.

Showerguard nano-coating products are user and environmentally friendly, all packaging including bottles can be recycled and the cloths can be re-used.

1.To refurbish existing showers and bathroom furniture firstly thoroughly clean all the area of built up limescale and soap residues with Signo Limescale remover in the pack, this needs to be applied and left for 20 minutes to work. Rinse thoroughly using a cloth (not provided) to remove stubborn marks.
2. Once the surface is dry and free from limescale and soap residue, prepare the surface by using the Pre-clean solution and the white cloth.
3. Coat with Showerguard™ when the surface is free from streaks. Using the blue cloth ensure even and complete coverage of the surface.
4. The surface can be touched immediately after coating, but it will be fully cured after 24hrs when the shower can be used
5. Ongoing cleaning will be easier and can be done with any suitable non-abrasive household glass-cleaning product, do not use abrasive scrubbing equipment for cleaning.

Helpful hint – when applying the Pre clean and Showerguard™ divide the surface into small areas to minimise rapid evaporation of the product.

Application Instructions

For showers/glass that has been in use for some time where contamination has built up, remove existing limescale and staining by following the Limescale and residue removal instructions below: –

Limescale and residue removal:- Spray the Signo limescale remover all over the glass surface from top down. Leave for twenty minutes for full activation, then return to rinse heavily with water using cloth (not provided) to rub away all residues; then dry thoroughly.

Note: If all limescale and contaminants are not removed on first attempt, re-apply, ensuring glass is completely clean and clear and then continue to Step 1 below.


For newly installed shower glass that has not been in use, continue to follow the instructions below (retain the limescale remover for other cleaning and de-scaling tasks): –

Coating glass (and ceramic) surfaces with Showerguard

1.Preparation of glass surface with Pre-clean

Ensure glass is dry, and clear of grease and dirt. Spray the inside of the glass screen with Pre-clean and rub the product into the glass surface with the pre-cleaning cloth (white). Divide the surface into sections for treatment of about 0.25m2 to minimise rapid evaporation of the product.

The glass is ready for coating application when streak formation from the Pre-clean is no longer evident. Apply the Showerguard™ coating immediately after the whole glass surface has been pre-cleaned and is dry and smooth.

  1. Coating with Showerguard™

After pre-cleaning, spray Showerguard™ onto the inside glass surface, ensuring good coverage. Spread the product around the glass surface with the coating cloth (blue) to ensure complete coverage of the surface.

Because of the rapid evaporation of the product, divide glass panes into sections for treatment of about 0.25m2. After spraying each section of glass, polish in one operation with the coating cloth. Continue to polish until the surface feels totally smooth. Each 30ml bottle should cover approximately 3m2 of glass. Use any excess product to treat the outside of your screen, or any other ceramics or porcelain, following the above pre-cleaning steps.
