    Grouting square edge porcelain

    I've been fitting a lot more square edged porcelain tiles recently & struggling to get a neat grout joint. Traditional ceramic tiles usually have a lot of suction & the grout stiffens up quickly, allowing it to be smoothed to a good finish with the sponge. Porcelain tiles have little or no...

    Floating Floor on Celotex Without Concrete

    Well, I decided to remove the screed, (it's going to provide hardcore for a driveway) This is the concrete below, it's a bit thin! This was a kitchen with a back door, with a very heavy concrete lintel above. When I removed the lintel, I just broke the bricks supporting it & levered it out...

I plumbed up 3 holiday cottages...
