The supermarket giant drew a line under its disastrous experiment with hardware on Wednesday, announcing the sale of its Home Timber and Hardware chain to Mitre 10's owner, Metcash, and the sale of its Masters Home Improvement stores.

Masters stores, including one at Heatherbrae, will close their doors for good on or before December 11, Woolworths said. It first flagged its exit from the business in January.

Port Stephens Council gave the green light for a $19 million Masters home improvement warehouse to be built at Heatherbrae in October 2012.

The store opened for trading in February 2014. At the time had 105 staff members on its books.

Everything from paint, timber, barbecues, vacuum cleaners and all other Masters stock, worth between $600 million and $700 million, will be sold off in a fire sale which is expected to start this week, a Woolworths spokesman said.

Woolworths expects to net $500 million from the discount sale. 

The company has appointed the Great American Group, part of one of the world's largest inventory divestment specialists, to manage the sell-off, with the support of Master staff.

Woolworths said it would honour customer gift cards, warranties, returns and laybys, and would complete any contracted installation projects.

"Since the sale process began, our 7700 staff in the Home Improvement businesses have worked extremely hard in an uncertain environment and we sincerely thank them for their commitment," Woolworths chief executive Brad Banducci said.

"We will work hard to find Masters employees jobs within the group or pay full redundancy where suitable roles are not available."

Since 2009, Woolworths and its joint venture partner, US hardware giant Lowe's, invested $3.48 billion in the home improvement project, including Masters and the profitable Home Timber and Hardware business.

Woolworths announced it was exiting hardware in January, after it racked up losses of more than $600 million in the four years prior.

Home Consortium, whose owners include the families behind the Chemist Warehouse and Spotlight, will buy the joint venture vehicle, Hydrox Holdings, for about $800 million including debt.

Home Consortium said it was already in negotiation with retailers including Anaconda, JB Hi-FI, Super Amart, BBQs Galore, Woolworths Supermarkets and Dan Murphy's to take over the 61 properties.

Bunnings confirmed it planned to take over 15 Masters sites. Eleven of those would replace existing stores. 

Woolworths will net $165 million by selling Home Timber and Hardware to Metcash, allowing it to merge with Mitre 10 and create a new $2 billion player in the sector.

Woolworths said it would make gross proceeds of $1.5 billion by selling out of its hardware assets.
