The Block is only a few days into renovations and already Foreman Dan has had a heated clash with a pair of contestants.

The frustrated tradie came to blows with West Australian couple Han and Can when the pair decided to take matters into their own hands and waterproof their bathroom.

Dan made it clear the team needed to wait for a waterproofer to do the job professionally, but they defied his orders and got started on the task.

Upon discovering that the pair had ignored his demands, Dan exploded.

‘What are you doing? You can’t be waterproofing,’ he told Han.

‘I just asked you, like, five minutes ago: You’re not allowed to waterproof. If I give you an instruction, you can’t disobey it.’

Dan raged that he has ‘lost trust’ in the pair after they sneakily applied a second coat of waterproofing agent despite his advice.

‘You’re not a licensed waterproofer; you’re not allowed to waterproof. You’re allowed to help waterproof, if the waterproofer is in there,’ he raved.

A furious Dan immediately reported the infraction to the site manager, leaving Han in tears.

‘Dan shut me down. He told me that I wasn’t allowed to touch anything. He thought I was being dodgy. That hit hard,’ a tearful Han said.

‘I’m disappointed in myself, because I didn’t listen. I’m really trying. I feel like I just got told off by my parents,’ she added, as her partner Can tried to comfort her.

The team were not penalised in the end, and did not lose any points, despite the clash.

On Sunday, the show kicked off with high emotion, unexpected confessions and more tears than tiles.

WA contestant Can, who is competing alongside her partner Hannah, was visibly emotional as she spoke about her journey with her sexuality, revealing this was the first time she’s come out publicly.

‘For a lot of my teenage years I felt a lot of shame and insecurity around my sexuality,’ Can said through tears in the show’s debut episode on Sunday night.

‘I have not professed that I have a girlfriend or that I am gay and I still hide it from certain people and in certain instances. So, to come on national TV is a big thing.’

Tears continued when Han and Can missed out on their dream home after coming fourth in the ChillOut Festival float challenge, which determined house selections.

They were devastated to be stuck with a flat-roofed house they didn’t want.

Han was so emotional she had a long cry in the bath while Can tried to cheer herself up by Googling design inspiration.

‘I hate it. It’s like letting go of my child,’ Han moaned.
