The Watts Gallery has received more than £1.5m for the sale of Jasmine by Albert Moore and The Triumph of Love by Edward Burne-Jones.
The gallery plans to put the money towards storage, framing and other aspects of the care and conservation of its core collection.
Andrew Churchill, the Watts Gallery's marketing manager, said: "The sale of the paintings was always about the care and conservation of the core collection, to provide a regular source of income for the coming years.
"It is a relief that the core collection is now secure. It was a difficult decision to take, but the only viable decision for the long-term future."
Caitlin Griffiths, the Museums Association's (MA) head of professional issues, commended the gallery's openness with both the MA and the sector as a whole.
"The case of the Watts Gallery demonstrates that there are exceptional circumstances when disposal can take place, but also what a time-consuming process it is, and not one to be undertaken lightly," she said.
The gallery aims to raise £10m to restore the building, conserve the collection, extend the education programme and establish the Watts Gallery as a centre for the exploration of Victorian art, social history and craft.
It has secured an earmarked grant of £4.3m from the Heritage Lottery Fund (HLF), but still needs to raise a further £2m to meet the conditions of the grant.
Isabel Goldsmith, a trustee of the gallery, said: "We hope that the result of this sale will give extra confidence to the HLF in making its decision to unlock the grant."
