How to Repair Damaged Aluminum Bullnose in In-Ground Pools

What You'll Need
Auto Body Hammer
Epoxy Filler

Most in-ground swimming pools are fitted with aluminum bullnose or coping. The coping functions to cover the rounded edges of walls. Because of this function, aluminum bullnose is placed on the junction between the floor of the swimming pool and the bottom of the pool walls. This leads to a distinctive curve in the swimming pool wall which serves aesthetic and practical functions. However, pool bullnoses are still vulnerable to damage and hence, may need to be repaired.

Step 1 – Know the Cause

It’s very important that you know the root cause of why your pool coping needs to be repaired. You will need to keep on repairing your pool aluminum bullnose again and again if you do not do something to that solves the underlying cause of the problem. Most of the time, the problem has something to do with water leaking to an expansion joint that was not adequately sealed off or a bullnose that was not thoroughly mixed with mortar.

Step 2 - Assess the Gravity of the Problem

You must be able to assess the extent of the damage. For one, you need to find out if the extent of your repair should only be limited to the surface of the coping or also to its sides. Also, you have to know if the action needed is something you can do with the pool still filled with water or if you have to drain the water out.

Step 3 – Hammer

For problems like a blunt object striking your in-ground pool’s aluminum bullnose, you should notice some kind of dent. Your coping will be bent producing a curved surface rather than a smooth, flat one. You can always reshape your aluminum bullnose by using an auto body hammer and doilies. Pound the damaged coping back to its original, or almost original, shape. The only down side to this method is that you will be using up a lot of time and strength in order for you to repair your aluminum bullnose.

Step 4 – Prime the Damaged Section

You need to wear your safety goggles for the priming procedure. You should clear the affected area of any detached pool coping as well as other kinds of debris.   Prevent these materials from flowing down the drain as they can clog up pipes. Removing any loose coping must be done with enough care to prevent further damage. You can cut the damaged coping off to make a straight edge at the same time making the repair procedure a lot easier on you.

Step 5 – Apply Epoxy Filler

Once you are done prepping the damaged area, you may then proceed to filling the dent with epoxy filler that is designed for metal exteriors. You can find the epoxy filler in any hardware store. Once you are done filling, let everything dry up first before sanding the repaired coping down to match the rest of the old coping. Paint the new coping with the exact color as the old coping.
