Frequently Asked Question:
How Long Does A Product Last or How Long Before I Need To Re-Coat?
Not all applications are the same. Lifespan as indicated may be achieved in many applications though it would be irresponsible for a supplier to provide a predetermined exact time frame when substantial variables exist from project to project. Variables include but not limited to are…
• Surface Preparation
• Correct Product For Application
• Application Method
• Application Spread Rate
• Cleaning Methods
• Substrate Type
• Substrate Condition
• Environment/Elements or If Internal/External
The use of solvents, acids and alkalis will also seriously reduce most products lifespan.
“Up To” Reference
For reasons described above, suppliers and manufacturers claims of expected wear will always make reference using words like “up to” or to a similar effect. In some cases products expected wear may exceed stated values, and in some case it won’t. Suppliers simply cannot provide more accurate expected wear claims for individual projects.
7 Main Types Of Sealers/Coatings and Expected Wear
• Silicates – The chemical reaction in silicate products form a calcium silicate hydrate barrier that permanently fuses within substrates pores and doesn’t break down. Silicates like densifiers are technically not considered sealers.
• Silane-Siloxane/Fluoropolymer and Siliconate Repellent Sealers – Typically known as penetrating sealers these may last up to fifteen years. See Penetrating Range. The “beading” action may fade anywhere from a few months (surface residue), but the protective action of the sealer continues working long afterwards. See How Do Penetrating Sealers Work.
• Acrylic Single Pack Repellent Sealers – They may last anywhere up to five years before another coating may need to be applied. Being a topical coating, expected wear will be determined predominantly by chemical exposure or surface abrasion. Please see in Clear or Coloured
• Epoxies/Urethanes Resistant Coatings – typically last up to five to ten years before re-application is necessary. Longest lasting out of all topical film forming coatings that do not re-form or re-activate when exposed to petro-chemicals. See 2 Pack Range.
• Paint (no sealer) – Due to an array of factors, there’s no surefire way to know how long paint is going to last. Typically a floor paint products lifespan is top coated with sealer to extend lifespan and minimise deterioration.
It is recommended a sealer be frequently tested and re-applied as necessary allowing for maintenance coats and optimal performance.
