Exposed aggregate concrete is an ideal material for surfaces such as floors, driveways and pavements. This type of material is favourable because of the beautiful surfaces created. The exposed stones on the concrete and the texture is visually appealing, particularly in comparison to plain concrete. Also, these surfaces provide more traction for vehicles and pedestrians. This slip-resistant aspect is valuable in areas where enhanced safety is critical.
In general, if you install an exposed aggregate surface, you will enjoy long-term service without extensive maintenance. However, external factors such as high mechanical force can contribute to the damage of the structure. The most common problem is the loosening of the aggregate stones. If you have noticed this form of deterioration on your exposed aggregate concrete, you should use the tips below to conduct long-lasting repairs.
Clean the Concrete
You should clean your concrete surface before beginning your repairs. Typically, the restoration of the damaged exposed aggregate section will require the use of patching products. If the surface is dirty, the material will not adhere and the stones will loosen again prematurely. You should sweep the area thoroughly to eliminate dust and debris. Then, you should use a hose and sprayer to clean out the residue dirt on the concrete.
Repair Cracks
You should repair cracks in the exposed aggregate surface before proceeding with the attachment of the dislodged stoned. The repair process for cracks is fairly direct. You will need to purchase a commercial concrete patching material from your local building store. Then, you should apply the material into the crack, creating a firm seal. You should allow the patching compound to cure completely before continuing with your repairs.
Apply Your 'Glue'
Next, you will need to apply the 'glue' which will be critical in keeping the aggregate stones in place. You can purchase an appropriate product such as clear aliphatic polyurethane from a supplier of concrete or construction goods. This fluid is not coloured, and it has strong adhesive properties. Also, the material will last long in adverse conditions. You should pour the material over the section of your concrete surface that you wish to repair and spread it thickly.
Place the Stones
Finally, you should obtain the decorative stones intended for installation on the surface. Where possible, these stones should be the same as those used in the original construction of the exposed aggregate surface. Place the stones on the patching compound and distribute them evenly for an attractive appearance. Once the 'glue' cures, your surface will look great.
