** Clearing the remaining wood/debris in your expansion joints is needed to prepare them for Gap Armour.    Removing wood 1-1/2″ down will provide plenty of room for Gap Armour, anything below that can be left in place (why work too hard?) as it will not affect the installation.  Some tools used to get the old wood out:  hammer, long screwdriver, chisel, mallet or other prying tool.   Don’t forget your safety glasses and some good knee pads!

Colors & Sizes

Want to find the perfect match for your cement area?  Gap Armour comes in 3 different colors giving you options like never before. Now you can match your cement area and also match surroundings like homes, siding, gutters or other finishings.   Choose an option that provides distinct lines in your cement area or an option that is more subtle and ‘hides’  the gap from being so noticible.

Gap Armour comes in 2 different colors: Graphite (grey) and Adobe (a med-dark tan).

Gap Armour comes in 4 different sizes: 1/2″, 3/4″, 1″ and 1 1/4″. Typical gaps in driveways and sidewalks use  3/4″ or 1″, but there are cases where the 1/2″ and 1 1/4″ are needed.     It is also very common for a particular job to need multiple sizes, even if the expansion joints all started out at the same size.  This is typically due to shifting and movement throughout the life of the concrete slabs.
