Epoxy Grout for New BTOs: Why Before Move-In Is the Cheapest Time

There is exactly one moment in your flat's life when epoxy grouting is at its cheapest and easiest: after your tiler finishes laying tiles, before anyone moves in. If your BTO's joints are still open — tiles laid, nothing grouted yet — this article explains why that window is worth catching, with the actual numbers.

Why open joints cost ~40% less

Re-grouting an older home has a hidden first stage: the old grout must be raked out to at least two-thirds of the joint depth before anything new goes in. That removal stage is the slowest, dustiest part of the work — and on our published tariff it is what separates the joint rates:

Same epoxy, same workmanship, same 5-year warranty — the difference is purely that there is nothing to remove. A full 5-room flat of newly laid 600×600 floor tile typically lands around $2,300–$2,800 on the tariff; the identical flat re-grouted a few years later costs thousands more.

The four-day rule that costs you nothing (for now)

Epoxy grout is walkable after 24 hours, but showers and wet areas should not see water for 4 days, with full chemical cure at about 7 days. In an occupied flat, four days without a shower is genuinely painful. In a BTO nobody lives in yet, it costs nothing at all. This is the second reason the before-move-in window is the right one — the only inconvenient part of the job happens while you are not there.

When exactly in the renovation timeline?

1. After tiling is complete — every tile laid, adhesive cured, joints clean and dry.
2. Before carpentry dust gets into the joints — or with joints protected/cleaned before we start.
3. Before the tiler cement-grouts by default. This is the trap: many tiling packages include cement grout "free". Once cement goes in, your joints move from the $5.04 rate to the removal rates above. If you want epoxy, tell your ID or tiler to leave the joints open.

What if my tiler already grouted?

Still worth doing — most of our work is exactly this — but do it knowing the arithmetic: recent cement grout must be raked out first, which is why the rate is higher. The one thing you should not do is wait for the cement grout to blacken first. It fails on its own schedule (typically years 1–3 in wet areas), and the price of epoxy does not go down while you wait.
