Hello and welcome back to another Prep, Set, Go episode. In today's video we'll be looking
0:08
at concrete repairs and how to choose the right repair mortar system for your application. So
0:14
let's jump straight in. Now there's a whole range of factors needing to be considered
0:18
when selecting the right repair mortar for your project to ensure the right outcomes.
0:23
The type of repair - This will always be your primary consideration. What's the application,
0:29
and what are you trying to achieve? With a myriad of repair motor systems available, identifying
0:34
the type of repair or application is the first step. So whether it's for structural repairs,
0:39
surface restoration and patching cosmetic touch-ups, levelling flushing or bonding,
0:45
there'll be a product designed and available for your specific application. The substrate,
0:50
consider the substrate you are repairing - whether it's concrete, masonry, stone,
0:55
or other building material. The selected repair mortar should be suitable and specified for use
1:01
over that substrate to ensure compatibility and to cater for any considerations specific to that
1:06
substrate. Strength requirements - Identify the required strength and general performance of
1:12
the repair mortar determined by specific projects. Mortars are available in various strengths ranging
1:18
from standard to high performance formulations. Durability - assess any environmental conditions
1:25
and exposure factors that may affect the repaired area, such as general weather conditions,
1:30
moisture, chemical exposure, and abrasion. Choose a mortar with the appropriate
1:35
durability characteristics to withstand these conditions over time. Application method,
1:40
consider the preferred application method whether it's hand application, trowel application, spray,
1:46
or pump. Ensure the chosen mortar is suitable for the desired application and allows for easy
1:51
workability and placement. Setting times. Evaluate the setting time of the mortar including initial
1:58
set and final cure. Depending on the project requirements and timeline, make sure to choose a
2:04
motor with a setting time that allows sufficient working time, without compromising on strength
2:08
development also consider weather implications and the direct effects of the installation and curing
2:14
of the repair motor system. Colour and finish. If the area is to be left exposed, or achieve a
2:20
certain aesthetic, select a repair mortar that matches the colour and texture of the existing
2:25
substrate or desired finish. Compatibility with additives - consider any additives or admixtures
2:31
that may enhance the performance of the motor such as accelerators, retarders, water reducers,
2:37
or polymer modifiers. Ensure compatibility between the mortar and any additives used
2:42
to achieve the desired property. In addition to considering all these points, remember to
2:48
always refer to the manufacturer specifications, technical data sheets, and application guidelines
2:54
for the chosen mortar. Follow recommended mixing ratios, application procedures and curing methods,
3:00
to ensure optimal performance and longevity of the repair. And if you're unsure speak to
3:05
your local RLA representative, or call the RLA Technical Services Department. We're sure to
3:10
