Manchester's BDH/TBWA has produced the spots to accompany the new series of Carlton's DIY show Renovation Street.
The 16-part series, which was launched last year, features the former Birds of a Feather star Linda Robson visiting streets, flats and communities around the South East, which are in need of renovation. As the jobs are tackled, she seeks expert advice that would help DIY enthusiasts.
The mouse is UniBond's attempt to show how easy its products are to use.
If successful, the agency plans to roll him out into other campaigns.
He features in three idents. The first, promoting UniBond's No More Nails, shows him jumping out of his chair as the shelf he has just put up crashes to the floor.
The second has him fixing a hole in his wall with No More Big Gaps. In the third, he puts Super All Purpose Sealant around his bath. The idents were written by Richard Sorenson, art directed by Matthew Crosby and directed by Mischa Walsh for Carlton Production.
The Media Shop is handling media buying for the initiative, which maintains UniBond's associations with DIY programming. Earlier this year it began sponsoring Handy Andy's Hints on GMTV.
