Quick answer
Treat wet weather as a change in operating conditions. Check how water reaches the shop floor, use suitable entrance controls and cleaning methods, and give someone responsibility for checking the result during trading. Signs warn people; they do not keep them off a slippery surface. Escalate recurring wetness instead of repeatedly recording it as cleaned.
Find the route the water takes
Observe the entrance during rain. Is water being tracked beyond the mat, entering directly through the doorway, dripping from umbrellas or coming from a leak? Note where people actually walk and whether the mat remains effective. Do not assume customers will stop and carefully wipe their shoes.
A retail discussion describes a small entrance mat doing little to contain wetness, with staff frustrated at repeated mopping. That is an anecdotal account, not a cleaning recommendation. The useful question for the owner is whether the entrance arrangement can cope with real traffic and weather.

Match the control to the cause
An HSE supermarket case study identified inadequate matting capacity and changed both cleaning arrangements and entrance controls. Its lesson is to examine the whole route water takes, not copy the site's equipment costs or assume the same result in your shop.
Ask an appropriate supplier or competent adviser about suitable matting and cleaning for your floor and traffic. Check that any mat sits securely and does not create a new trip obstacle or obstruct access. If there is a leak or unsuitable entrance design, give the underlying repair an owner as well as arranging immediate precautions.

Specify what happens while the area is wet
HSE's retail guidance says signs and cones only warn; they do not prevent people entering an area. Plan how access will be controlled while cleaning leaves a surface wet, using arrangements appropriate to the layout and risk assessment.
A small shop may have only one customer route. That makes the plan more important, not optional. Staff need a clear escalation point if they cannot maintain safe access while trading. Do not tell a lone cashier to watch a queue, control the entrance and clean continuously without practical support.

Review the result during the weather, not just at close
Choose a checking pattern based on actual conditions, and increase attention when rain or footfall changes. Record problems and actions that matter rather than filling a page with identical ticks. A photograph can help explain the location of a recurring problem, but it cannot establish the floor's slip resistance.
After the next wet trading period, ask whether the same patch kept returning, whether staff had the right equipment and whether the entrance controls stayed in place. Use that information to improve the arrangement. Keep a premises repair open until it has been dealt with; the daily cleaning record should not conceal the reason water keeps arriving.
Use Unpickle for the agreed entrance checks and problem follow-up. Staff still assess the actual conditions and act immediately; the app does not detect wet floors or replace your risk assessment. Record checks and unresolved problems.
