- Subfloor leveling
A strong alternative to LevelQuik when you need to fill deeper low spots, thanks to its 1.5 in single-pour depth. Slightly more forgiving flow, but like all self-levelers it lives or dies by proper priming.
Pros
- Pours up to 1.5 in thick in a single lift, so it fixes deeper dips that a 1 in-max leveler can't in one pass
- Extended flow keeps it self-leveling a bit longer than the fastest rapid-set products, easier for beginners
- Tile-ready in about 6 hours and walkable in 2, keeping a weekend bathroom project on schedule
Cons
- Still needs the matching Henry primer on porous and non-porous substrates, skipping it invites debonding
- Deep 1.5 in pours consume bags fast, cost climbs quickly on a badly sloped floor
- Not a wear surface, it must be covered by tile or flooring and can't be left exposed

Frequently Asked Questions
- How thick can Henry 555 LevelPro be poured in one pass?
- From 1/8 inch up to 1.5 inches in a single lift. That depth is its main advantage over levellers capped around 1 inch, because deeper dips get corrected in one pour instead of two.
- How much floor does a 40 lb bag cover?
- About 43 sq ft at 1/8 inch. Coverage falls quickly as depth increases, so a badly sloped floor consumes bags and budget much faster than the bag count alone suggests.
- Do I really need the primer?
- Yes. It requires the matching Henry primer on both porous and non-porous substrates. Skipping primer is the most common cause of debonding, where the leveller cures into a slab that is not actually bonded to the floor beneath it.
- How soon can I tile over it?
- Walkable in about 2 hours and tile-ready in about 6, which is what keeps a weekend bathroom project on schedule.
- Can it be left as the finished floor?
- No. It is not a wear surface and must be covered with tile or flooring.
