How to fix crack in bath?

Question

Hi

There is a crack on the floor of the bath. It feels like the reason for this is unstable base as when you tap it, feels hollow. What is the best way to repair this? The floor feels like a plastic material so I'm guessing it's acrylic or fibreglass material.

Hello @rkini

For an even stronger patch, you can use PC Marine. Just make sure to use disposable gloves when handling the product.

Hi @rkini

You bath already  cracked and will fail more.

Why not  think about drilling a 12mm hole in your bath at the crack and mixing a wet sand and cement slurry and  a funnel and pouring the slurry through re bedding the bath in this location?   Slurry just wet enough to pour through funnel until no more  will pour. This will help make a cement bed under the pressure point,  Or can you lift the bath and do this?

Also drill 4 mm holes at the outer most tip of those cracks  as its how they fix aircraft cracks in non critical spots as the crack runs into the drill hole and  stops it in its tracks as the round hole flexes evenly and presents no new exit points for stresses to find and takes  much greater effort to spilt further.

What about adding builders  joint tape as it is designed to strengthen patches and is thin so the epoxy can imbed between the fibres.

Thanks Eric. Can I use PC Marine instead of PC11? This is basically to get a white color.
