I have just finished renovating an investment property we bought 2 months ago, and it's finally ready to be listed for rent. There aren't many properties of this calibre in the market. The concrete driveway and concrete in the front garden area were looking tired and have been pressure washed. There are some gaps in the concrete at the edges and cracks in many places. I have quotes of $10K+ to rebuild the driveway (after removing existing concrete and pour new concrete), but can't afford to spend that much. I have received 2 other quotes that are lower and more affordable, but need advice on how long these would last.
1) Concrete repair, removal of damaged cracked concrete areas where required and repair with new cement around the front driveway and inside the garage; approximately 10-15 bags of cement required. At least a week after the concrete has been poured, acid wash and pressure cleaning. Seal driveway, garage and concrete surrounding the garden beds with a) White Knight White Heavy Duty Ultra Pave Concrete And Paving Paint I/N: 1540599, mixed with b) White Knight 200g Ultra Pave Grip Additive I/N: 1540637.
2) Acid wash and pressure cleaning. Seal driveway, garage, and concrete surrounding the garden beds with a) White Knight White Heavy Duty Ultra Pave Concrete And Paving Paint I/N: 1540599, mixed with b) White Knight 200g Ultra Pave Grip Additive I/N: 1540637.
Questions on Option #1:
A) Will the cement adhere to the old concrete in option #1?
B) Will this be rugged enough for a driveway?
Questions on Option #2:
C) Any way to fill the cracks and holes before painting?
D) Apart from acid washing, any way to improve the adhesion of paint to old concrete and reduce peeling of paint?
