Mould around kitchen sink

[jharr]

In the house I'm renting I would like to get rid of the mould at the back of the kitchen sink and keep it at bay for a year or more, see photo.

Determined cleaning with baking soda and vinegar will get rid of a little of it, which grows back.

Where the concrete counter behind the sink meets the concrete wall something has been applied to seal it, which is not silicone or soft.

The mould seems ingrained in that material and in the surrounding concrete.

This area is wet a lot of the time.

So looking for suggestions using materials readily available here.

My thinking so far is to:

• spray with undiluted bleach and leave for several hours (maybe hydrogen peroxide or something else is better?)

• wash off

• dry and leave to dry for a day or more

• prime once or twice (Jotun Cito 09 or a TOA primer?)

• top coat two or three times (TOA Supershield?)

Or am I likely better off in the long term getting someone in to re-do the area?

Cheers

Stick some tiles on it,other wise it will just keep coming back

For Gods sake man get it tiled and make a proper job of it.

I bet water is pissing in under the sink aswell?

 

If I saw a restaurants kitchen like that it would be the last time I eat there.

If you dont like tiles you could make a stainless steel or perspex splashback.

 

Must admit that gap at the back of sinks is always a nuisance and collects water whatever is on the wall

Maybe the water is coming from the window, or sink. Anyway it needs to be removed, cut out. A job for the LL.

A back splash or tile on that wall will solve your problem. Wall tile is a pittance in Thailand and costs so little to have installed. Use proper tile adhesive and better grade Weber tile grout for wet rooms and you will have a longer lasting solution. Don Chance, Eyecatcher, Worgeordie, have given you valuable advise.

Thank you all for the suggestions.

Looks like tiling is the way to go.

Thanks kamalabob2 for the grout brand name.
