Preparation Steps for Resin Tub Repair: Essential Guide

← Back to How to repair a tub with resin?

What prep is needed for resin tub repair?

Getting your tub ready for a resin repair is crucial for lasting results. Proper prep ensures the resin will adhere securely, creating a durable, waterproof fix, whether you’re tackling a hairline crack or a larger hole.

Step 1: Clean and Dry the Surface

Start by removing all dirt, soap scum, oils, and any loose material from the repair area. Use a household cleaner and a non-abrasive sponge, taking care to rinse thoroughly. After cleaning, dry the surface completely, as moisture can prevent the resin from curing or bonding effectively. Pay close attention to corners and seams where water might linger.

Step 2: Sanding for Better Adhesion

Once clean and dry, carefully sand the damaged area and a small border around it. This helps to roughen the surface, so the resin can grip more securely. Use medium-grit sandpaper and wear gloves to avoid irritation. Remove any dust with a damp cloth and allow everything to dry once again.

Step 3: Degrease Before Application

Before applying your chosen repair product, it’s important to remove any remaining grease or contaminants. A dedicated degreaser or acetone works well for this step. Wipe the prepared area gently, then let it air dry. This final clean ensures optimal bonding for products like the Resin Fibreglass Repair Kit or CROP 2K Fiberglass Putty.

When Is Careful Prep Especially Important?

Thorough preparation matters most if your tub repair will be exposed to water or regular use—such as repairing baths, showers, or poolside tubs. Any missed steps can lead to poor adhesion, meaning the repair may not last.
