The best varnishes for tiles, compared.
Top pick: Cadence acrylic varnish, 500 ml Best value: HG tile protector, 2 × 1 L – Lowest price per litre in this set, about £12.95, with the listing naming floor tiles, flagstones and slate. Updated October 2026.
Varnish for tiles, on a UK floor, is a clear coating for quarry, unglazed tile, slate or stone. On amazon.co.uk the same browse also includes a thin polymer polish and a craft acrylic. It is the wrong default for a closed glaze, a shower or exterior slate. We used the amazon.co.uk lines for this set and did not run a laboratory test. None of these tins prints a pendulum value. How to separate a film, a polish and a sealer that is not here is in the [varnish tiles buying guide](/hub/paints-and-varnishes/varnish-tiles/sub/varnish-tiles-buying-guide). Polyvine Varnish, part, is a water-based polyurethane from the United Kingdom. The technical sheet names quarry, unglazed tiles, slate, cork, stone, brick, wood and emulsion, and it says interior.

Question 1 of 2
What are you coating?
Cadence acrylic varnish covers a listed 5–7.5 m² from its 500 ml bottle and names ceramics, tiles and stone among its recommended craft uses. The stone-varnish instructions call for two coats, but the listing gives no drying time beyond saying that it dries quickly. Its finish field says matt while the title and bullets mix matt, gloss, semi-matt, velvet and stone-varnish variants, so it is not clear which finish the single bottle represents. The 4.8-star rating is the highest in this set, but it comes from only 16 ratings. The two available written reviews are from Turkey, mention neither tiles nor floors and therefore offer little evidence for a UK floor project. This is better treated as a small craft coating than as a substitute for a specified floor varnish.
Pros
Cons
Best for: Small decorative ceramic, tile or stone craft projects where a 500 ml pack is sufficient.
Less suitable: Tiled floors, large areas or any project needing a clearly specified finish and floor-wear performance.
Specifications
Common questions
Does the listing say this is for tiles?
Recommended uses are paints, ceramics, tiles, stone, a kitchen counter and parquet. A bullet says the stone varnish is for ceramics, tiles, stone, a kitchen counter and parquet, and that it should be applied twice. The compatible-material field says stone.
Which finish is in the 500 ml bottle?
The finish field says matte. The title also lists semi-matt, gloss, stone varnish and velvet. The unit count is one 500 ml item. The listing does not say the bottle contains all of those finishes.
Are the reviews in the file from the UK?
The star line is 4.8 from 16. The file has two reviews, both from Turkey. One says the product is nice and that shipping was fast. The other is a thank-you. Neither describes a floor.
Polyvine Heavy Duty Floor Varnish forms a clear satin floor coating on interior quarry tiles, unglazed tiles, slate and stone, with the technical sheet giving a 16-hour cure at 20°C. Its 2-litre tin should cover about 20–40 m² using the maker's 10–20 m²-per-litre range, although the Amazon listing presents the coverage in two different ways. The water-based polyurethane is touch-dry relatively quickly and can be recoated after about two hours, so the long wait is before normal use rather than between coats. The two available UK reviews praise easy application, and one reports durable results in hard-wearing areas after several years. Neither review describes a tiled floor, however, and the listing has only 12 ratings in total. This is the top pick for a properly prepared porous interior floor, but it is not specified here for glazed porcelain, showers or exterior patios.
Pros
Cons
Best for: Prepared interior quarry tiles, unglazed tiles or slate where you want a clear satin floor film.
Less suitable: Glazed porcelain, showers, exterior patios or floors that need a documented slip-resistance value.

Common questions
Does this listing say it can be used on tiles?
The bullets name tiles, slate, cork tiles and quarry tiles, with wood and stone. The compatible-materials field lists ceramic, glass, leather, metal, paper, plastic, resin and wood. The title says indoor flooring.
What coverage and cure does the listing give?
The bullet says 15–20 m² per litre. The coverage attribute says 30–40 sqm. Touch dry is 45 minutes, recoat is 1–2 hours, and cure is 16 hours under ideal conditions. No VOC figure is printed.
What do the reviews in the file say?
The listing is 4.5 from 12. Two UK reviews are in the file. Both praise easy application. One calls it tough in hard-wearing areas after several years. One mentions a clear shine. Neither names quarry tiles or slate.
HG Tile Protector spreads as a thin protective coating over floor tiles, flagstones and slate, with listed coverage of about 40 m² per litre for each layer. At £25.90 for two 1-litre bottles, it is the lowest-cost option per litre in this three-product set and our best value. The five available UK reviews include use on slate and Minton tiles, with users describing renewed shine or sheen. Application needs care across a large floor because one reviewer reports foam-roller dimples and another noticed overlap marks. The listing also contradicts itself by calling the finish both satin gloss and matt, while its anti-slip statement has no published test value. It suits a low-cost refresh of compatible indoor stone or tile, but buyers who need a precisely specified finish or verified slip performance should look elsewhere.
Pros
Cons
Best for: Refreshing compatible indoor slate, flagstones or floor tiles on a limited budget.
Less suitable: Large areas where lap marks would be conspicuous, or floors requiring a verified sheen or slip rating.
Specifications
Common questions
Which floors does the listing name?
The title names floor tiles, flagstones and slate. Bullets add marble, quartz and other natural stone in a hall, dining area, kitchen or bathroom. The page asks about kitchen floors, marble and slate.
Is the finish satin or matt?
The title says satin gloss. One bullet calls it a fast-drying anti-slip matte formula. The old name on the page is HG Protective Coating Satin Finish (P14). The new name is HG Tile Protector (P14).
What do the UK reviews in the file say?
Five reviews are in the file, against a 4.3 from 30 on the listing. They mention shine on slate, a sheen on Minton tiles, and a slate kitchen. One reports dimples from a foam roller and overlaps on a large floor. One says the bottle label did not match the advert.

Varnish for tiles means a clear coating on quarry, unglazed tile, slate or stone. On these three amazon.co.uk listings you also get a thin polymer polish and a craft acrylic. Read the substrate, whether the product forms a film, and whether the sheen lines agree, before you read the sticker price. None of the tins prints a pendulum test value. We did not run a laboratory test.
A varnish for tiles is a clear coating you put on a porous mineral floor so the face has a film. In this amazon.co.uk set that job is one product. The other two are a thin polymer polish and a 500 ml craft acrylic that sit in the same browse. Polyvine Heavy Duty Floor Varnish, part VHD6, is a water-based polyurethane from the United Kingdom. The June 2026 technical sheet names quarry, unglazed tiles, slate, cork, stone, brick, wood and emulsion, and it says interior.
Polyvine’s amazon materials field lists ceramic, glass and metal as well as the floors on the technical sheet. Lithofin says a glazed face is closed and that wax or acrylate films bind dirt. A shower and an exterior patio are outside this set.
Polyvine’s sheet says about 30 minutes dry and a 16-hour cure at 20°C. The amazon bullets say touch dry in 45 minutes and recoat in 1–2 hours. Touch-dry is not ready for foot traffic. Do not apply below 8°C or above 30°C.
EN 71 on the Cadence listing is toy safety, not floor wear or a wet-feet certificate. HG’s Non Slip line and Polyvine’s anti-slip claim have no pendulum value. HSE GEIS2 bands are 0–24, 25–35, and 36 and above. No tin here prints a figure.
Start with the job the sheet names, not the word tile in a title. Polyvine’s June 2026 sheet names quarry, unglazed tiles, slate, cork, stone, brick, wood and emulsion, interior. The amazon materials field is wider and includes ceramic, glass, leather, metal, paper, plastic and resin. Do not treat that field as permission for glazed porcelain. HG names floor tiles, flagstones, slate, marble, quartz and other natural stone, indoors.
Read sheen from one line and notice when the listing disagrees with itself. Polyvine satin is this tin. Dead flat is another product, and the sheet puts dead flat over two satin coats when you want flat and still tough. HG’s title says satin gloss and a bullet says matte. Do not treat that clash as a finish you can specify. Cadence’s finish field says matt while the title lists semi-matt, gloss, stone varnish and velvet. The brand field on the HG page says GH. The manufacturer is HG.
Three typical situations, each with a recommendation from this comparison.
You want a clear film on a prepared porous interior floor and you can wait out a 16-hour cure. Polyvine Heavy Duty Floor Varnish, satin, is about £63.83 for 2 litres. The sheet names quarry, unglazed tiles and slate. It is 4.5 from 12 reviews, and those reviews do not name a tiled floor.
You are refreshing dull indoor slate, flagstones or floor tiles and you want the lowest price per litre in this set. HG tile protector is about £25.90 for two 1 litre bottles, about £12.95 a litre, with 4.3 from 30 reviews. The listing disagrees with itself on sheen.
You are coating a ceramic piece, not a floor, and a 500 ml bottle is enough. Cadence is about £18.49. The finish field says matt while the title mixes several finishes. Do not treat the 4.8 from 16 as UK floor reviews.
The top pick is Polyvine Heavy Duty Floor Varnish, satin, 2 litres, at about £63.83. The maker’s sheet names interior quarry, unglazed tiles and slate, and it gives a 16-hour cure at 20°C. The score in this set is 91. Amazon.co.uk shows 4.5 from 12 reviews, and the two UK reviews in the file do not name a tiled floor. HG tile protector is the best value at about £12.95 a litre, with UK comments on slate and Minton tiles and a listing that clashes on sheen. Cadence stays a craft acrylic: the title mixes finishes, and the written reviews are not UK floor reviews.
