The porch of my house currently has paved brick surface. There are 3-4 steps followed by a bigger porch platform. Some of the bricks have become loose and wobbly. This is risky as someone can get misbalanced and have a fall. I am considering covering the area with epoxy or concrete resurfacing but not sure what would be the most suitable and long lasting material for this.
I would appreciate advice from the expert on the best product to use. In the past I have tried fixing the loose bricks with brick cement but that didn't help.

Hi @husainZahid,
I think there are really two separate issues going on here, and it is important to tackle them in the right order.
The first priority is the safety issue with the loose and wobbly bricks. Any type of coating, whether epoxy or a resurfacing product, will only sit on top of what is already there. It will not fix movement underneath, and in fact it is likely to crack or fail quite quickly if the bricks are still unstable. Before you think about covering or coating anything, the steps and porch need to be made solid again.
To do that, the loose bricks will need to be lifted and checked to see what they were originally bedded into. In some cases, they are set into mortar, in others, it can be more of a sand and cement base. If mortar has failed or is too thin, simply patching with brick cement often is not enough, which sounds like what you have already experienced. Depending on the situation, you may be able to re-bed the bricks properly, or in some cases, a strong landscape construction adhesive can be used to glue the bricks back down securely. The key thing is that once finished, there should be absolutely no movement at all.
Once the brickwork itself is repaired and stable, you can then look at the appearance. I'm not aware of any epoxy or resurfacing products that are suitable for going directly over a brick-paved surface. You could paint the bricks using a concrete and paving paint, which will change the look and can make the area easier to clean, but it is purely a surface treatment. It will not add strength or stability, and it relies entirely on the bricks underneath being sound.
If the idea behind coating was to try and solve the wobbling, the movement has to be fixed first at the brick level. After that, repairing and keeping the existing brick finish, or painting it for a cosmetic update, are both realistic options.
Please let me know if you have any questions.

Yes, the idea would be that you glue down the loose bricks @husainZahid. If more than a handful of bricks are loose, you would likely need to investigate why. This could involve pulling them up and investigating what's going on underneath. Perhaps the stairs need to be rebuilt.
The problem is that surface coatings do not fix underlying structural issues. They need to be applied over a sound surface. Further to that, you would need to speak with a specialised coatings company to determine whether there is something that could be applied over them, which could cover the brick joints. Other than paint, which won't disguise the bricks beneath, there's really no other coating I am aware of. Epoxies must be applied over a solid concrete surface. If you were to apply them over bricks, they would crack.
