A new survey has shown that 75% of Scottish people will wear face coverings.
Just 43% of Welsh respondents said they had worn a covering or mask in the last two weeks, and 65% in England.
Wales is the only country in Britain where face coverings are not required to be worn in shops to help prevent Covid-19 transmissions, but like in the rest of the UK they are mandatory on public transport.
First Minister Mark Drakeford has said he would not mandate the use of three-layered face coverings in public places like shops because the country had the two-metre social distance requirement written into its regulations.
But he said that could change depending on the state of the virus in Wales in future, while claiming businesses could request customers wear the coverings anyway.
In response to the poll, Andrew RT Davies, the Welsh Conservatives' shadow minister for health, urged requiring more people to use face coverings to avoid a resurgence of the virus.
He said: "Welsh Conservatives have always believed in being ahead of the curve when it comes to the Covid virus.
"That's why instead of waiting for an increase in cases as the Labour First Minister seems to want to, we believe that greater use of face masks should be mandated by the Welsh Labour Government to help avoid an uplift in the number of cases of Covid in Wales.
"Act today to save lives tomorrow."
A Welsh Government spokesperson said: "The evidence remains clear the most effective way to protect yourself and others is to follow social distancing rules, avoid touching surfaces and your face, and wash your hands regularly.
"Face coverings are not a substitute for these measures, but in some circumstances where it may be difficult to stay two metres away from others, we advise the use of face coverings."
The YouGov survey was one of a series it focused on the difference in people's behaviours between the three countries.
It said the results showed how each nation's government has impacted public behaviour.
Another poll found that people in Wales were the most likely to actively avoid contact with tourists (41%) compared to Scotland (33%) and England (30%).
And Welsh residents were the most likely to support the decisions taken by their government, including stopping all inbound flights (38%, vs 31% in Scotland, 27% in England) and temporarily closing schools (29% vs 21% and 22% in England and Scotland).
The survey also found that people in England were the least likely to support quarantining people and placing areas back into lockdown (30%) compared to Scotland (39%) and Wales (43%).
England was also the country which had the least support for quarantining someone who had come into contact with a contaminated patient (65%) vs 75% and 76% for Scotland and Wales respectively.
Scotland was the country where the most of respondents felt the Covid-19 situation was getting better or completely over (80%) compared to Wales (64%) and England (38%).
However the survey noted its work in Scotland was conducted in late July, prior to the recent outbreak in Aberdeen.
