Spray sealant
A spray sealant is a fast-applied liquid protection product wiped on after a car wash to add gloss, hydrophobicity, and short-term protection.
What it means
Spray sealants are the modern take on between-wash protection. The product is sprayed onto a freshly washed and rinsed panel, wiped lightly with a microfibre, and the formula bonds to the surface as it flashes off. The result is a slick, beading layer that adds gloss and lasts anywhere from a few weeks to a few months depending on the formula and conditions. Spray sealants come in two main flavours. Polymer-based sealants behave like a faster-applied version of a traditional polymer sealant. SiO2-based sprays use the same chemistry family as ceramic coatings but at much lower concentration, giving a coating-like feel and beading without the multi-stage prep or curing of a true ceramic. Spray sealants are typically used as a between-wash protection layer, as a top-up over an existing ceramic coating to refresh hydrophobicity, or on cars where committing to a full ceramic coating is not the right call.
Why it matters in Singapore
Singapore's monsoon-and-sun cycle wears down protection layers fast. A spray sealant takes ten minutes to apply per panel and refreshes beading immediately, which is useful between professional grooming sessions. For ceramic-coated cars in particular, periodic SiO2-based spray top-ups extend the time between major refresh visits.
How Revol Carz handles this
Revol Carz applies a spray sealant after every car wash where the customer's protection is showing wear, and as a top-up over ZeTough ceramic coatings on customer request.
