Topical Silicone-Enhanced Concrete Sealants Fish-Eye Primer Just Like Penetrating Silicone Sealers
A Penrith entertainment precinct carpark had standard asphalt for most of the parking area, but the pedestrian entry section adjacent to the venue had a polished concrete surface finished with a topical densifier sealant. The sealant happened to contain a silicone-based additive to improve water repellency. We applied primer to the full carpark including the polished concrete section.
Fish-eye craters appeared across the polished concrete section within minutes of primer application — same as the Seaford VIC job and the Waurn Ponds VIC job, but from a topical sealant rather than a penetrating sealer or spray seal. Silicone additives in any surface product — penetrating sealers, topical sealants, spray seals, waterproofing coatings — create the same fish-eye problem because the mechanism is identical: reduced surface energy preventing primer wetting.
The bead-water test doesn't distinguish between topical and penetrating silicone treatments — it identifies any silicone contamination. Perform the bead-water test on every concrete and treated surface before applying primer, regardless of what the surface treatment was. If water beads, silicone is present and grinding is required.
Penrith is western Sydney's outer commercial hub — Panthers precinct, the entertainment and hospitality businesses, and the Penrith CBD fringe industrial and commercial facilities. Transport NSW approved. Bead-water test on every polished or sealed concrete section before primer on any Penrith mixed-surface carpark.

A penetrating densifier is impregnated into the concrete matrix by capillary action during application — it reacts within the pore structure. A topical sealant is applied to the cured polished surface and forms a film on top of it rather than penetrating into the concrete. Both can contain silicone additives. Both cause fish-eye defects in subsequently applied coatings if silicone is present.
Polished concrete in entertainment and hospitality environments is chosen for its appearance. Topical sealants are applied to protect the polished surface from staining and to improve cleanability. Silicone additives increase water beading and stain resistance — properties that are valuable for venue flooring but problematic for subsequent coating adhesion.

Light diamond grinding removes the topical sealant and the top 0.5-1mm of the polished surface. The polishing can be reinstated by the flooring contractor after marking if the decorative appearance needs to be restored. In most external carpark applications the polished surface is a transition zone between the venue entrance and the asphalt carpark — the marking covers the grinding marks.
