Some epoxy grouts do not need a sealer. LATICRETE names SPECTRALOCK PRO Premium and SPECTRALOCK 2000 IG among its epoxy grouts that do not require grout sealer, and Sika says its SikaTile-825 epoxy grout requires no sealer. Before paying for sealing as part of a commercial floor-cleaning job, identify the installed product and check its instructions. LATICRETE’s grout guidance; SikaTile-825 product information. [6]
Start with the grout name, not a general rule
“Epoxy” and “cement-based” describe categories. For a purchasing decision, ask for the actual product name and its manufacturer’s care guidance. You can ask the property owner, original installer or maintenance contractor for installation records and details of later treatments. If nobody can identify the product, ask how the contractor plans to resolve that uncertainty before you authorize a sealer. [1] [7]
Include past color treatments in that conversation. LATICRETE explains that grout colorants form a surface coating that also seals grout. A record of a previous colorant application therefore gives the contractor another treatment to account for when discussing the current surface. LATICRETE’s cement-grout FAQ.
What the named manufacturers say
| Product or guidance | Sealing position |
|---|---|
| LATICRETE SPECTRALOCK PRO Premium and SPECTRALOCK 2000 IG [1] | LATICRETE says these epoxy grouts do not require grout sealer. [1] |
| SikaTile-825 epoxy grout [5] | Sika lists no sealer requirement. [5] |
| Sika’s guidance on cementitious grout [5] | Sika recommends a compatible sealer; check the instructions for the installed product. [5] [6] |
These are manufacturer-specific examples, drawn from LATICRETE’s FAQ and Sika’s product page. They do not establish one sealing requirement for every grout.
MAPEI’s explanation also distinguishes a recommendation from an industry requirement: it says the tile industry does not require sealing, while recommending it especially in wet or busy areas. The same article recognizes products marketed as not needing sealer. Avoid turning “cement-based” into an automatic sealing instruction; check the exact product. MAPEI’s explanation of grout sealing.
The adjacent tile is a separate question
A grout that needs no sealer does not settle the question for the entire floor. LATICRETE discusses tile or stone that requires sealing even when installed with its epoxy grout. Ask the contractor to distinguish treatment of the grout from treatment of the adjacent tile or stone. LATICRETE’s epoxy-grout FAQ.
For the proposal, you can ask which surface the sealer is intended to treat, what product is proposed and which manufacturer instructions apply. That makes “seal the floor” a more specific item to approve or decline. [6] [7]
What to discuss with MB Clean Solutions
MB’s tile-and-grout service page lists penetrating grout sealant application. It also says pricing depends in part on whether sealing is included. MB’s tile and grout cleaning service.
At the assessment, ask whether the proposed scope is cleaning alone or cleaning with sealing. If your installed grout is one of the products whose maker says no sealer is needed, bring that information to the discussion. If sealing is proposed for the tile or stone instead, ask for that distinction in the quote. [5] [1]
You can use these questions to compare the offered work:
- Which grout and tile products have been identified? [7] [1]
- Does the grout manufacturer recommend, permit or say there is no need for sealing? [6] [5]
- Is the proposed sealer intended for the grout, the tile or both? [7] [1]
- How does the proposal account for any previous colorant or coating? [1]
- Can the quote show cleaning and any proposed sealing separately?
Before you approve sealing
Choose the scope from the product information and the assessment. A cleaning quote does not have to settle the sealing decision before the grout is identified. You can ask for the sealing item to remain unapproved while you gather records or discuss the manufacturer’s guidance. [2] [6]
To review your floor’s cleaning needs, request an assessment from MB Clean Solutions and share whatever grout, tile and maintenance records you have. The useful question is which treatment this floor calls for, rather than whether every commercial grout should receive the same service. [2] [7] [1]
