How to repair the worn enamel of your bathtub?

If your bathtub enamel is worn or has lost some chips, it is quite possible to repair it. Here are the steps to follow.

Clean the enamel surface

Over time, the surface of the enamel becomes loose and becomes porous. Lime settles there all the more easily. In a spray bottle, combine white vinegar, lemon juice and coarse salt. Spray the mixture on the enamel and leave to act. After a few minutes, rinse off with clean water.

Scrub your tub with a soft sponge so as not to further damage its surface. If the enamel has tarnished, rub with a little baking soda to revive the whiteness. Finally, soak a clean cloth with turpentine and rub to restore shine to the enamel.

With acetone, soak a cloth and degrease the tub. Then sand the enamel to remove the rust.

Recap the shards

If your enamel is cracked or if chips are visible, fill them in. This will not only be an aesthetic advantage, but also a way to properly protect the materials and reduce the risk of infiltration.

Equip yourself with two-component epoxy resin, based on putty and a hardener. Refer to the manufacturer’s instructions to form a homogeneous paste. Apply it with a spatula on the places to be repaired. Smooth then eliminate the overflow. Let dry well then sand the filled areas before dusting.

How to paint your bathtub?

To give a new shine to an aging bathtub or to give a facelift to old-fashioned equipment, it is possible to paint its surface. Here are the steps to follow.

Prepare the surface

Clean the tub with white vinegar to remove all lime residue. Make sure you have properly filled all the holes in the enamel with two-component epoxy resin. If not, now is the time!

Then sand the entire tub and clean again with rubbing alcohol or acetone to thoroughly degrease the surface.

Paint the tub

Take care to protect areas not to be painted, such as faucets and tiled borders, and remove old joints. Use a two-component epoxy resin paint to paint the enamel and obtain a lasting result; a traditional paint will indeed not be able to hold on a surface like the bathtub. Prepare your product by referring to the manufacturer’s instructions. Apply the paint with a small foam roller on flat surfaces and with a small paintbrush for outlines and hard to reach places. Do not overload with resin.

Let dry, sand lightly then apply a second coat. Quickly remove masking tape.

Apply the finish

For a more harmonious and more durable finish, apply a transparent finishing resin. The surface will be brighter and more solid, able to resist water and cleaning products.

Proceed as for painting.

How to redo your silicone bathtub seals?

If you haven’t already, remove the old gasket from the tub to replace it with a new one. This operation is essential for a more aesthetic rendering, but above all to avoid infiltration. Here’s how to do it.

Remove the old gasket

Using a gasket remover, remove the old silicone gasket from your tub. Just slice off the ends and slide the blade under the joint. Then pull the seal by hand. You can then dissolve the small stubborn pieces with a gel polish remover that should be left on for 1 to 2 hours. Remove residue with a wet sponge and degrease the area with rubbing alcohol or acetone.

Install a new gasket

After having cut the tip of your silicone cartridge, screw the cannula and cut the end so as to respect the width of the necessary seal. Place the cartridge in place and pull the trigger to release the sealant.

Apply your silicone with a precise, regular and slow enough gesture for an optimal and harmonious result. To do this, pull the gun towards you.

Wet your finger in a little soapy water and use it to smooth the joint in one motion along the entire length. With your cutter, cut the excess silicone.
