Many types of Kwik Kerb Continuous Concrete Edging will be “sealed” upon completion with a special sealing solution. This product is specifically designed to help cure the concrete as well as protect the surface finish from sun damage and weathering. Depending on the edging location and weather conditions, this sealer may need to be re-applied every two years or so, to maintain the original beautiful appearance of your edging. Please call your Kwik Kerb operator for an estimate on the cost of doing this regularly if you do want to maintain the original shine and lustre forever.
STAINS & STUFF THAT GROWS
Certain lawn chemicals contain copper sulphate and other ingredients which can stain your edging. Please avoid spraying the Kwik Kerb edging with chemicals. Mould or mildew sometimes appears on the surface of the concrete. It can be removed with a bleach solution and a small scrubbing brush. Rinse the edging thoroughly once clean. The sealer which has been applied will assist in the prevention of this problem. If necessary have the sealer re-applied after removal of mildew.
All colored concrete fades to a degree. With lighter colors this effect is much less noticeable. The special process by which your Kwik Kerb edging is created ensures the maximum amount of color pigment at the surface of the edging to ensure fading is minimized. (Methods used by other edging companies do not concentrate the color pigment at the surface in this way and severe fading can result.) Kwik Kerb operators are very well trained, use a special sealing process and the finest natural and man made ingredients in the manufacture and installation of your edging. Any fading which occurs is natural and unavoidable. Periodical applications of sealer will protect your investment for many years to come.
Efflorescence is a white powdery substance that sometimes forms on concrete during the first few weeks. It is caused by evaporation of water from the surface of the concrete which leaves behind the minerals (which were in suspension) as a salt deposit. It causes unsightly white stains which can be particularly objectionable on colored concrete. The correct application of sealer during installation minimizes the risk of this effect. If some efflorescence does occur you can remove it by washing with a weak acid solution (dilute pool acid at 1 part acid to 12 parts water). Make sure you rinse the edging with a garden hose after washing with this acid solution. Always use gloves and eye protection when using acid.
