Light Bagging of Exterior Brick Retaining Walls

$2,000

Terrigal NSW, Australia

7th Oct 2025

I need someone experienced with exterior wall finishes to lightly bag (not render) a series of painted brick retaining walls in my backyard. The goal is to refresh the surface with a natural, semi-textured “bagged” look that still shows some of the brick outlines — not a full smooth render. Scope of Work: • Clean down walls (remove loose paint, dirt, and debris). • Apply a light bag coat using mortar mix or premade bagging/render mix — aiming for a soft, rustic texture. • Blend finish evenly across all visible wall sections - see attached photo for reference. • Tidy up and remove any mess on completion. Notes: • Existing paint is white; new bagging to be white/off-white to match or refresh the existing colour. • Walls are all accessible (see photos). • Please bring all your own tools and materials. You’ll need: • Experience in bagging/rendering exterior brick • Own trowels, sponge floats, drop sheets, etc. • Ability to produce a consistent light finish (sample area can be agreed before doing the lot) Timing: Flexible — preferably within the next 2 weeks, weather permitting.

Adam did an incredible job bagging a bunch of exterior walls. Very professional responsive and a lovely guy, thanks Adam!
