Little or nothing needs to be done to protect the finish of natural concrete fountains and statuary. Many people find the inevitable aging and weathering of natural stone to be appealing. However, this natural weathering may be impeded, if you wish, by the application of a clear concrete sealer available from any hardware store.
Many Henri finished fountains and statuary have been painted with penetrating, sealer-type colors that are designed to resist the elements for many years. A painted fountain's clear luster, however, may be revived seasonally with a light coat of Henri sealer spray. Do not use the sealer spray on a stained-finish fountain.
To camouflage minor dings, nicks, or scratches, use just a dab of almost any sort of paint. For finishes that employ a black antique effect, use black paint; for lighter antiques, use white. Simply dab the paint onto the scratch and wipe of the excess. The textured finishes of Henri cast stone products accept paint easily, and your touch-up will blend in invisibly.
Depending upon temperature and evaporation, you may notice a build-up of white residue (limescale) on the surface of a bowl or shell. Such a build-up is normal and unavoidable in areas with high mineral content, especially lime, in the local water supply. More frequent rinsing of the fountain and changing of the water will help minimize the problem.
When scaling build-up finally becomes unsightly on a painted bowl or shell, it may be safely and easily removed with Henri fountain cleaner and lime remover. This product is not a water additive but a surface cleaner specifically designed to foam away lime residue without affecting the fountain surface. Do not use the lime remover on a stained-finish fountain.
To keep fountain water clear from unsightly sludge, algae, and cloudiness, simply use Henri water clarifier. It also prevents fountain water from becoming dirty, and so it will also improve filter efficiency in your submersible pump.
Extreme and rapid changes in temperature and humidity affect all concrete adversely. Concrete has an inherent tendency to expand and contract with climatic conditions.
However, your Henri cast stone products have been manufactured with weather in mind. The concrete mix contains fiber and mechanical additives that enhance the elastic qualities of the concrete. Occasionally, non-harmful surface cracks may appear - but your Henri cast stone product will not crack due to weather if the following simple rules are followed:
- Do not allow waste to collect and freeze in fountain bowls or shells.
- Do not allow water to collect and freeze in planters, saucers, or birdbaths.
- Do not allow statuary or pedestals to sit in a pool of ice.
Cast stone products left exposed to icing conditions may shale or crack due to the mechanical force of water solidifying and expanding along the concrete surface.
Important: If your Henri fountain, birdbath, planter, or statuary cannot be stored indoors during the winter season, you must at least protect it from ice collection or exposure.
How To Protect During the Winter:
For fountains, first remove the statue and pump (storing them inside if possible). Next, fill the bowl(s) or shell(s) with an absorbent material such as burlap bags or blankets. Then, cover the entire fountain with a Henri fountain cover. Should condensation form inside the cover, they will be absorbed by the material.
For birdbaths, planters, or statuary, set the pieces on high ground where a pool of ice will not form, then cover with a Henri fountain cover.
By following these simple and sensible precautions during the winter season, you will protect your Henri Studio cast stone products for many years of beauty and enjoyment.
