Product Description

Smartseal Porcelain Sealer is a hard wearing, breathable, protective coating for modern internal & external porcelain tiles. The porcelain tile sealer can also be used on ceramic wall and floor tiles. Furthermore, it helps to prevent general soiling & surface staining. Although this is not a cosmetic product, it does act as a colour enhancer and leaves a subtle wet look sheen once dry. However, its main purpose is to make cleaning and maintenance easier.

Smartseal Porcelain Sealer is a ready to use, easy to apply, quick-drying formulation that gives additional protection oil and water-based stains whilst enhancing the natural colours of the tiles. Once applied the porcelain tiles sealer will make cleaning and maintenance of porcelain surfaces much easier. WE DO NOT RECOMMENDED USING ON HIGHLY POLISHED SURFACES.


  • Suitable for use on porcelain and ceramic tiles
  • Strictly a single-coat application
  • Leaves a subtle wet look sheen once dry 
  • Enhances the colours of the tiling
  • Can be used externally on patios
  • Also for use on walls and floors internally
  • Ultra-durable sealer for long term protection

Formula is ready to use, quick drying and easy to apply.

Average coverage: 10 - 20m per litre, dependant on surface texture and porosity.

Product FAQs

Q: How can I remove porcelain sealer easily

William Nunn

A: Would be best to get in contact with our Technical Team so they could help advise you on removing Porcelain Sealer.

Response from Ricky

Q: Will the sealant also work on the grouting, or does it need to be done separately? If so, which should I do first? Many thanks.


A: The porcelain sealer will also protect the pointing or grout between the porcelain tiles. Hope that helps.

Response from Nigel

Q: Hi. How long should it be left before re-applying? 2-3 years? Thanks


A: Thanks for the question. Usually the sealer would protect between 3-5 years. We would suggest to try a test area in 2-3 years time to see if more sealer will adhere for a light top up coat.

Application temperature range: 10 to 23C

Directions for Use:

Always apply to a test area or spare tile first.

Only apply to completely dry and clean surfaces.

**If applied to a surface where a "sweep-in" pointing compound has been used within the last 6 months, the porcelain must be fully cleaned with Smartseal Residue Remover prior to sealant application.**

Apply a single thin, consistent coat, with a microfibre cloth, microfibre flat mop or paint pad. Avoid application marks and excess pooling of sealer.

Please note:

This formulation is strictly a single coat application, because it is a high active micro coating that bonds very strongly to the impervious porcelain.

It is not a cosmetic product. Although it does make the treated surfaces look more attractive, its main purpose is to aid easier cleaning and maintenance.

Applying more than one coat to achieve the "desired appearance" will almost definitely result in application issues and product failure.

Given the above, it is important the exact application instructions are followed.

  • Allow a minimum of 2 hours drying time before walking on. The sealer will be fully-cured and attain full water-resistance after 24 hours.

  • If using externally, do not apply if rain is forecast within 8 hours.

  • Average coverage 10-20m per litre. Coverage will vary depending on surface texture and porosity.

  • Store in cool, dry conditions out of direct sunlight in original container only. USE WITHIN 6 MONTHS OF PURCHASE & WITHIN 3 MONTHS ONCE OPENED.
