Weed killer for patio and driveway
Updated: October 2026
You are on the block paving with grass in the joints and a bottle that only says path in the search title. A weed killer for patio and driveway is worth buying when the amazon.co.uk listing names those surfaces, and when you spray the weed rather than the whole slab. In this set of seven, three bottles name paths, drives, patios or gravel, and three others only receive the patio question. Prices sit on the [weed killer comparison](/hub/weed-control/weed-killer). This page stays with moss, a leaking pump, one stain report, and the drain. The Products Compared editorial team wrote it on 16 October 2026 from those listings and public UK sources, not a laboratory trial. A qualifying purchase can earn us a commission at no extra cost to you.

Which listings name the surface
Check the bullet, not the search title. Resolva Path & Drive, 3 litres (B0GJTQJD4Q, £18.00), names paths, drives, patios and gravel, and it names pelargonic acid. The 5 litre power pump (B0GJTGTCCB, £25.99) names the same surfaces, though the active is not stated. Home & Garden Gallup, 1 litre (B0F2GVG8BD, £21.75), names paths, driveways, patios and garden areas, and it is a 360 g/L glyphosate concentrate you dilute.
Roundup Total Fast Action, two 1 litre sprays (B0HGBK3T8H, £12.98), names no surface. Reviewers mention patio edges, and the listing says apply to the weed only. Patio is asked and not answered on Resolva 24H (B001DYSARM, £9.70), the Pump 'N Go 5 litre refill (B01CNEM3EG, £25.99), and Topline Xpress 24H (B0C4Z2TJBW, £23.99).
Gallup is the awkward named bottle. The title says home and garden and also industrial, no MAPP number is in the file, and some reviewers guessed the mix. Compared with a ready-to-use spray, do not start there for a few joints. A weeding knife, then another cut a fortnight later, is what the Royal Horticultural Society puts first in a narrow joint.
Moss and algae
Only the two Resolva Path & Drive bottles claim weeds and moss, plus algae, with results within hours and use all year as stated. The 3 litre names pelargonic acid and prints no root sentence. On the 5 litre the active is unstated. One reviewer calls that liquid a contact killer that leaves deep perennials, which is a review, not the specification. A brown cushion is not a clear drive until spring, because no listing here names a residual.
The 3 litre is 4.3 from 46 reviews. Paths going clear is the praise, a minority say it failed, and moss is barely discussed. Wickes quotes 30 or 90 square metres, and acetic acid, for a 3 litre Path & Drive. This amazon.co.uk file prints neither, so do not copy those shop lines onto the bottle. Root claim versus scorch sits on glyphosate or contact weed killer.
Pumps, leaks and stains
The 5 litre Resolva costs £25.99 and scores 3.8 from 27 reviews. Buyers praise the liquid and fault the sprayer: no pressure, a seal out of place, a short lance, and leaks after a refill. If the lance will not hold pressure, those extra litres never reach the weed. Compared with the 3 litre at £18.00, the volume helps only when that pump works on the day.
One verified review of the Pump 'N Go refill, rated 4.6 from 7,749, says the glyphosate refill stained block paving. That is one report, not a rule that every weed killer marks stone, and not proof that glyphosate never does. Marshalls warns that ferrous sulphate stains. That is different chemistry, so the two warnings stay apart. On a pale slab, spray one joint and look once it is dry.
Take the refill when you already own that Pump 'N Go. The listing says it is that refill, it claims a root kill in one to two days, and patio is asked but not answered. Who should skip a weak pump is on best weed killer.
Joints, gravel and run-off
Spray the weed you can see. Liquid on the whole slab runs into the joint and the gully, and it is not a better treatment. A 2012 Health and Safety Executive amenity note, not printed on these ASINs, says foliar sprays on non-porous surfaces should hit visible weeds and should not overspray drains. Another Roundup Path & Drive label says do not treat near drains. That sentence is not on these seven files. Product still must not go into a drain.
Gravel is named on both Resolva Path & Drive bottles, and you still spot-treat, because nothing here claims a residual. If the fall is into a gully, leave the drive, and call someone trained for Japanese knotweed or if spray would wash into the drain. Topline is not a patio product: the question is unanswered, and reviews dispute the lawn bullet.
Use the 3 litre Resolva for named surfaces and moss when you have no pump yet. Use the Pump 'N Go refill when you own that sprayer and want the root claim, knowing patio is unanswered and one buyer reported a stain. Leave the 5 litre pump and Gallup unless that sprayer works and a dilution is printed.
Common questions
Which of these seven name paths, drives, patios or gravel?
Resolva Path & Drive 3 litres and the 5 litre pump name paths, drives, patios and gravel. Gallup 1 litre names paths, driveways, patios and garden areas, and you dilute it. Roundup Total Fast Action names no surface. Patio is asked and not answered on Resolva 24H, the Pump 'N Go refill, and Topline Xpress 24H.
Will a path spray kill moss?
Only the two Resolva Path & Drive bottles claim weeds, moss and algae on hard surfaces, with visible results within hours. The 3 litre names pelargonic acid and does not claim a root kill. No bottle here names a residual, so browned moss is not a clear drive for the year.
Is the 5 litre Resolva pump worth it for a drive?
It costs £25.99 against £18.00 for the 3 litre, and it scores 3.8 from 27 reviews. Buyers praise the liquid and report no pressure, a loose seal, a short lance and leaks. The extra volume helps only if that pump holds pressure on the day.
Can weed killer mark block paving?
One verified review of the Pump 'N Go 5 litre glyphosate refill says it stained block paving. That listing is 4.6 from 7,749, so this is one report, not a rule for every bottle. Marshalls' ferrous sulphate warning is different chemistry. Test one pale joint and look once it is dry.
Can I spray the whole patio, or only the weeds?
Spray the weeds you can see. None of these listings names a residual that keeps bare slabs clear, and paving carries liquid towards gullies. A 2012 Health and Safety Executive note, not printed on these ASINs, says foliar sprays should hit visible weeds and should not overspray drains.
Will it stay out of the drain?
Only if you keep it off the grating. The Health and Safety Executive says not to put weed killer into drains. Leftover product goes to a household waste recycling centre as hazardous waste, not down a sink. Skip a drive that falls straight into a gully.
Can I use the Topline lawn bullet on grass next to the drive?
No. Topline Xpress 24H is a glyphosate-free contact refill at £23.99, about 125 to 250 square metres, and patio is asked and not answered. One bullet mentions lawn weeds, and reviews say not to use it on lawns. Guidance G212 does not treat contact sprays as a lawn product.
