Acid etching is a process to remove the surface cement matrix to varying depths. The depth of the etch can be from light to heavy removal of the matrix. This can be done first by grinding the surface or direct application of the acid solution. It is an attractive and visually appealing finish which vastly improves the slip resistance of the concrete. The process and appearance is not to dissimilar to the traditional exposed aggregate driveways - however with one major advantage.
The Pavilion finish is wonderful to walk on with bare feet as the aggregate is either ground flat prior to being exposed or it is only slightly exposed giving a light sandpaper feel. This produces a non slip finish - naturally - in the subsurface so it is perfect for all external concrete finishes including driveways, alfresco's, paths, steps and around pools. The final steps are to apply a penetrating sealer followed by 2 coats of clear sealer in low sheen finish.
The process is tedious and requires specialised equipment and trained operators to avoid issues, but the rewards are worth it.
Concrete colors and aggregates can be selected to customise your desired finish.
This process can be carried out on new and old concrete, however the surface must meet a certain standard. So for best results speak to Marco about concrete finish and placement requirements on new concrete so you have a quality outcome for your project.
This is the traditional concrete finish to external concrete. This finish is smooth in comparison to the Pavilion or acid etched concrete. The concrete is ground back to produce a flat even surface and then ground further if required to achieve the right level of aggregate exposure. The concrete is then cleaned up with finer and finer diamonds then grouted to fill holes / cracks and finally sealed with a clear acrylic in matt or semi gloss.
