How to specify concrete work gloves for wet cement, mortar, rebar tying and concrete block handling, with practical coating choices, EN 388 targets, cuff lengths, MOQ, lead time, inspection points and factory limits.
Wet Cement Is a High-pH Exposure, Not Just Dirt
Fresh cement paste and mortar are strongly alkaline, commonly around pH 12 to 13.5. The injury risk is cement burn when wet slurry stays against skin, especially inside a knitted cuff, under a damaged liner, or between fingers where coating coverage is thin. A 13 gauge PU palm glove may be fine for dry assembly, but PU is not a reliable liquid barrier for wet cement. It will not stop slurry entering through the back of hand, finger crotch or wrist. Before asking a factory for concrete work gloves, split the job into at least two applications: wet placement and finishing, then dry block, masonry and rebar handling. Wet placement usually needs a fully coated or long-cuff glove, often PVC, nitrile or latex depending on grip, flexibility and site chemical rules. Dry block handling needs abrasion life and grip on rough edges, often a 10 gauge or 13 gauge liner with crinkle latex, sandy nitrile, or a leather reinforced palm. Trying to buy one cheap glove for every concrete task usually fails in the field. A thick 35 cm PVC gauntlet protects better during clean-up but feels clumsy when tying 1.2 mm rebar wire. A flexible 13 gauge sandy nitrile glove handles tools well but is not designed for repeated immersion in wet cement. Good sourcing starts with separating wet chemical contact from dry abrasive handling.
Coating Choices for Cement, Block and Rebar Work
Sandy nitrile on nylon, polyester or HPPE blend liners is a practical option for damp block, rebar prep, formwork pins, scaffolding clips and general site tools. A 13 gauge liner gives better finger feel for tying wire and setting anchors. A 10 gauge liner is bulkier but normally survives rough block edges longer. For EN 388:2016+A1:2018, many masonry buyers target abrasion level 4 and tear level 3 or 4. Cut level should come from the hazard, not from a catalogue habit. Crinkle latex gives strong dry and wet grip on concrete block and is usually more flexible than heavy PVC. It is common on 10 gauge polyester or cotton-polyester liners for low to mid-price masonry gloves. The limits are oil resistance, certain chemical exposures and latex allergy policies. If a distributor sells into latex-free construction sites, natural latex should not be specified just because the grip sample feels strong. PVC is useful for long-cuff wet slurry gloves, especially 27 cm, 35 cm and 45 cm gauntlet styles. It gives better coverage than a palm dip and can be easier to clean after mortar work. The trade-off is bulk, lower breathability and weaker small-part dexterity. Smooth PVC can be slippery on wet block, so buyers should confirm whether they need rough finish, sandy finish or double-dipped construction. GloveMark can produce common nitrile, latex and PVC coated work gloves, including 10 gauge and 13 gauge knit liners, palm dip, three-quarter dip, full dip and long cuff options. We do not claim that a normal nitrile palm-coated glove is automatically a chemical protective glove under EN ISO 374-1. If the product must claim resistance to sodium hydroxide, cement admixtures or cleaning chemicals, the finished glove construction needs lab testing by a recognised body.
Cuff Design Is Often the Failure Point
For wet concrete, the wrist design can decide whether the glove works. A knitted wrist is comfortable for dry block handling because it keeps grit out and holds the glove in place. In wet placement, the same elastic cuff can absorb cement water and hold alkaline slurry against the skin. Workers often notice the problem only after the glove is removed and the wrist is irritated. For wet pours, clean-up and reaching into forms, specify a safety cuff, gauntlet cuff or extended coated cuff. A practical two-glove programme is 13 gauge sandy nitrile with knitted wrist for dry masonry and rebar prep, plus a 35 cm PVC or fully coated nitrile gauntlet for wet placement and wash-down. If workers wear the glove over a jacket sleeve, do not write only size 10. Add glove length, cuff opening and acceptable tolerance to the tech pack. As a working example, a 35 cm gauntlet with an inside cuff opening of 15 to 17 cm fits over many light jacket cuffs. A narrow 12 cm opening may be comfortable on bare forearms but will fight with winter clothing. For long cuff gloves we usually ask the buyer to approve hand fit, cuff diameter and cuff stiffness, not just colour and logo. Sample approval should include a wet grip check. Dip the glove in water or a controlled cement slurry substitute, then handle block, trowel handles and formwork parts. Factory samples can look correct on a table and still fail because the cuff slides down, traps grit, or becomes too stiff when wet.
Abrasion, Cut and Puncture Must Match the Real Hazard
Concrete blocks destroy gloves mainly by abrasion. Rebar, tie wire, mesh and broken block add cut and puncture risk, but not every masonry glove needs the same cut level as sheet metal handling. EN 388:2016+A1:2018 reports abrasion, coupe cut, tear and puncture, with ISO 13997 cut rating A to F where applicable. For general concrete block work, abrasion level 4 is often more useful than chasing cut level E if the glove becomes too stiff to grip a trowel. If the job includes exposed rebar ends, sharp mesh, broken block edges or formwork metal, a cut-resistant liner may be justified. Common constructions include HPPE with nylon, steel fibre or glass fibre. A 13 gauge HPPE glass fibre nylon liner with sandy nitrile gives better cut performance than basic polyester latex, but it costs more and may feel harsher inside. A 10 gauge heavy liner can improve wear life but feels warmer in summer site work. Puncture wording needs care. The EN 388 puncture test uses a standard probe and does not equal nail-proof protection. It is not a hypodermic needle test and it should not be sold as protection from nails in timber formwork. If nail puncture is the buyer's real concern, say that clearly. A dipped knit glove with a thicker palm or leather patch may improve abrasion, but it will not become a certified nail-proof glove. For buying control, ask the supplier to quote the exact liner yarn, gauge, coating type and target EN 388 result. A vague line such as cut resistant concrete glove gives factories too much room to substitute cheaper yarns.
Leather Reinforcement and Real Factory Limits
For dry block handling all day, leather reinforcement can outlast a basic palm dip at the thumb crotch and palm heel. Split cowhide is common for abrasion and cost control. Goatskin gives better dexterity but costs more. Specify leather thickness, such as 0.9 to 1.1 mm goatskin or 1.1 to 1.3 mm split cowhide. Words like heavy duty leather are not enough for consistent quoting. GloveMark can source and assemble coated knit gloves, leather reinforced palms, thumb crotch patches, sewn safety cuffs, woven labels and some TPR impact parts. We can combine a dipped liner with a stitched reinforcement when the construction is practical for bulk sewing. We are not a specialist moulded chemical glove factory for butyl, Viton or heavy neoprene gauntlets. If your risk assessment needs EN ISO 374-1 Type A chemical protection in those materials, we would rather decline early than quote outside our real production base. For leather PPE, buyers should check EN ISO 21420 general requirements, including innocuousness and chromium VI control. Leather colour, oil content and odour can vary by batch, so a bulk inspection should include pair weight, leather defects, stitching, size grading and thumb crotch placement. On mixed leather and coated styles, we lock a golden sample before mass production because a 0.2 mm leather change can alter fit and dexterity.
MOQ, Lead Time, Testing and Inspection Controls
For straightforward private label coated concrete work gloves, realistic MOQ is usually 3,000 to 5,000 pairs per colour and coating type. Sample development is normally 7 to 14 days after artwork, size ratio and packaging details are confirmed. Bulk production is commonly 30 to 45 days after deposit and approved sample. Add time if the order needs non-stock yarn, custom coating colour, moulded TPR, special cuff tooling or third-party EN 388 testing. Price depends on liner, coating weight, cuff length and reinforcement. A basic 10 gauge polyester crinkle latex glove, a 13 gauge nylon sandy nitrile glove, a 13 gauge HPPE cut C sandy nitrile glove and a 35 cm PVC gauntlet are different cost families. For FOB Ningbo or FOB Shanghai, carton planning also matters. Coated knit gloves often pack around 120 to 240 pairs per export carton depending on thickness. Long PVC gauntlets take more volume, so container loading can drop sharply even when pair price looks attractive. For inspection, use ANSI/ASQ Z1.4 or ISO 2859-1 with agreed AQL levels, commonly 2.5 for major defects and 4.0 for minor defects on work gloves. Check coating cracks, missed dip areas, pinholes on full-dip gloves, wrong size marks, cuff length tolerance, pair weight, logo position, carton labels and barcode accuracy. For wet cement gloves, add a simple water leak or seepage check where the construction is meant to be liquid resistant. If the glove carries EN 388 or EN ISO 374 claims, test the finished production construction, not a similar stock glove. Changing from 10 gauge to 13 gauge, from smooth nitrile to sandy nitrile, or from knitted wrist to extended cuff can change performance. A proper tech pack should list yarn, gauge, coating, cuff length, size range, packaging, inspection AQL, Incoterms and whether lab testing is included in the quoted price.
