DIY stores

There are the Chino shops that sell just about everything except building materials.

Small tools, electrical goods, small appliances 

There are 2 on B commercial centre.

If you want a place more like B&Q then you will have to travel to a Leroy Merlin store at either Cartagena or Murcia.

They have a website that you can access in English.

There a lots of builders merchants locally for building materials

Thank You Roland for your quick reply. Was mostly after bags of sand and cement and patio tiles.

Things like that are better purchased from the local builders merchants,

There is one in El Pareton that sells stuff like that.

Just on the side of the road in El Pareton, you can't miss it,

Plenty of others round & about though.

For sand cement and tiles big mat near decklids and opposite mercadona 

I personally won't buy any more tools from chino as a waste of money and not good quality.
