Best jointing sand for block paving

Updated: 21 October 2026

You want a named amazon.co.uk bag for a loose top-up, a narrow joint that should harden, or a small run, not a slogan on the sack. The top pick is the sand whose stated job matches the joint, with a review file large enough to show the failures as well as the praise. Shelf prices and star lines are the ones in the [joint sand comparison](/hub/flooring-tools-and-accessories/joint-sand), captured on 19 October 2026. How to choose the type before the brand is on the [joint sand buying guide](/hub/flooring-tools-and-accessories/joint-sand/sub/joint-sand-buying-guide). Peter F. scored the seven listings, not a lab.

Best for a joint that is meant to harden

Sika setting sand, buff, 20 kg, B01JYXFRFG, is £21.99, with 4.2 from 2,591 reviews. That count is why it is the top pick for a joint that is supposed to set. The bullets say 2–5 mm and light vehicles. Sika UK asks for at least 25 mm of depth, no pre-fill, and not at 5°C or below or if rain is imminent. Sweep the excess off, then soak with a hose or a fine rose, not a pressure washer. Surface dry is one to two days. Full cure is up to 28 days. Weeds, ants and shade differences still come up. The material field says Silicone and the item form says Liquid, Paste. The title says setting sand. The loose-versus-cure fork is on kiln dried sand vs setting sand.

Best value loose sand

Laeto’s 20 kg, B0C19CF82X, is £16.14, 4.1 from 520 reviews, about £0.81 per kilo. The technical block claims 20 m², and a bullet includes artificial grass as well as joints. The bullets talk about locking pavers. Reviewers say it is ordinary kiln-dried sand and does not set. There is no millimetre width. Buy it as loose sand you brush in dry. UHL’s 19 kg, B0H5CRQJTC, is £13.50, about £0.71 per kilo, 5.0 from two reviews, with one written note and no fault stated. Dimensions are listed as 1 × 1 × 1 cm. Two reviews cannot show washout, so the lowest price per kilo is not the best value.

When Dansand is the pick

Dansand is not one product here. The 10 kg No Grow, B09SHVMSSH, is £12.32, 4.0 from 369 reviews, joints up to 5 mm, about £1.23 per kilo. A bullet also says twenty kilogram bags. Trust the title. Reviews include wash-off after a few days of rain. The 20 kg No Grow, B09B3XVNJN, is £20.39, 3.9 from 308 reviews, beige, up to 5 mm, coverage 5–10 m², with washout, weeds within a week, and a review that likes that it does not dry hard. Easy Fix, B00N2U2L34, is £23.99, 3.8 from 471 reviews, with no millimetre width and the same part string, RED Dansand. The polymeric bag, B09SH3FTC6, is £32.72, 4.0 from 96 reviews. Firm-setting is claimed and the reviews split. Choose Dansand when you want a brush-in inhibitor and you will keep the joints full. The weed wording is on does jointing sand stop weeds.

What best does not mean

A 5.0 from two reviews is not a ranking. Wickes has listed Dansand No Grow 20 kg at £14.50, a shed price, not the £20.39 on B09B3XVNJN, and that does not change the review themes. Nothing here is shown to stop weeds permanently, to kill roots, or to meet a BS 7533 sieve curve, because none of the listings prints one. Top pick means Sika when you will mist a 2–5 mm joint and wait. Best value means Laeto when you want loose sand whose reviews say it does not set.

Common questions

Which bag is the top pick if I want a joint that is supposed to set?
Sika setting sand, buff, 20 kg, B01JYXFRFG, at £21.99 with 4.2 from 2,591 reviews in this file. It is specified for joints of 2–5 mm and light vehicles, and you have to sweep the excess off and soak it. Skip it if the joint is under 2 mm, if rain is due, or if you will not wait through a cure that Sika states as up to 28 days. Weeds and ants still appear in the reviews.
Which bag is the best value if I only need loose kiln-dried sand?
Laeto, 20 kg, B0C19CF82X, at £16.14 with 4.1 from 520 reviews. Reviewers say it does not set, which is what you want from loose sand and not what the locking bullets imply. UHL is cheaper per kilo at £13.50 for 19 kg, but 5.0 from two reviews is not enough evidence to call it the better buy.
Why is a 5.0 score from two reviews not the winner?
Because two reviews, and one written note with no fault, cannot show washout, staining or weeds. UHL’s dimensions line also says 1 × 1 × 1 cm, and the listing has no joint width. A perfect star line on a thin file is a gap in the evidence, not a test result. Laeto’s 520 reviews are the loose-sand file that actually describes the product.
Is the polymeric bag the premium choice?
It is the dearest, at £32.72 for 20 kg, with 4.0 from 96 reviews. Firm-setting is a claim. The reviews in this file split between a joint that set and joints that emptied or never hardened. There is no millimetre width in that file. Pay the premium only if you accept that split, not because a higher price has proved a harder joint.
Is Dansand Easy Fix a different product from the 20 kg kiln-dried bag with the same part string?
The part string RED Dansand appears on Easy Fix, B00N2U2L34, and on the other 20 kg No Grow listing, B09B3XVNJN. The ASINs, prices and review counts are different: £23.99 and 3.8 from 471, against £20.39 and 3.9 from 308. Easy Fix does not state a millimetre width. Treat them as separate listings and read the page you are about to order.
Who should skip Sika?
Skip it if your joints are narrower than 2 mm, if you cannot sweep the face clean before you wet it, or if rain is imminent or the temperature is 5°C or below. Skip it if you wanted kiln-dried sand you can top up without a cure. The silicone and liquid fields on the listing are not a reason to buy it as a sealant. The title is setting sand.
