Rayson PrimeBond S30
Rayson PrimeBond S30 is a two-part, low-viscosity, solvent-based epoxy primer that penetrates and seals prepared concrete, pavements and mineral substrates before coating.
ConcreteCement screed TDS RY-TDS-103
Best for
Best for priming dense or absorbent concrete on car park decks, ramps, walkways and industrial floors where deep penetration is needed.
PrimeBond S30 uses a low-viscosity, solvent-based epoxy formulation to soak into prepared concrete and bind the surface before the floor system goes down. The two parts mix 1:1 and react to form a long-lasting sealing coat with excellent adhesion — pull-off testing on prepared concrete produces failure in the concrete, not the primer.
Its penetration makes it well suited to dense concrete, where two thin coats wet out the surface far better than one heavy application, and to porous or highly absorbent substrates such as pavements, ramps and loading bays. The cured film shows excellent impact and chemical resistance.
As a solvent-based product, PrimeBond S30 needs adequate ventilation during application and cure. For occupied buildings or enclosed spaces where odour is a constraint, consider the solvent-free PrimeBond E20 or water-based PrimeBond W10 instead.

Typical systems
Dense concrete sealing
- Apply first coat of Rayson PrimeBond S30 and allow to penetrate
- Apply second coat to achieve a uniform sealed surface before the specified finish
Limitations
- Minimum substrate temperature 5 °C; curing between +10 °C and +35 °C; concrete moisture content maximum 5%
- Mixed material must be used within its pot life; cures faster in hot weather and in large batches
- Solvent-based — provide adequate ventilation; not recommended for occupied areas without ventilation control
- Not a wearing surface — must be overcoated
Not suitable for
- Occupied or poorly ventilated areas — solvent-based formulation
- Use as a finished wearing surface without an overcoat
- Substrates with moisture content above 5%

Quoted after inspection The practical details
Rayson PrimeBond S30: questions people ask
Why does dense concrete need two coats?
Dense, power-floated concrete absorbs very little primer, and porous concrete absorbs unevenly. Two thinner coats achieve consistent wetting and a uniform seal, which prevents defects in the finish coats above.
Can PrimeBond S30 be used indoors?
Only with adequate ventilation during application and cure — it is solvent-based. For enclosed or occupied areas, PrimeBond E20 (solvent-free) or PrimeBond W10 (water-based) are the safer choices.
How long before the deck can take traffic?
Keep heavy traffic off for at least 8 hours after application on pavements, and note the primer itself is not the wearing surface — full return to service depends on the complete system. Confirm programme timings with our technical team.
What preparation does the concrete need?
Mechanical preparation by shot blasting, milling or diamond grinding to a sound, open surface, with weak concrete removed, defects patched and all dust vacuumed off.
Does it work on damp slabs?
Substrate moisture must not exceed 5%. For slabs that cannot meet this, PrimeBond E20 tolerates damp surfaces — discuss the slab condition with our technical team.
