The Potters have won only one of their last 22 away Premier League matches - against West Brom in December - ahead of Saturday's clash at Fulham.
Walters said: "I didn't realise the away record was that bad.
"It would be something nice to improve on. Well, we can only improve on it really.
"But there's no (psychological) barrier. We don't go into any game thinking anything except trying to get a result.
"The Stoke fans spend a lot of money and they are working-class people, so it would be nice to give them a win on the road.
"We've got to keep chipping away at that record and if we can keep our home form going, then we can have a good end to the season."
