Plan the job
Floor, subfloor, area. One order.
Three answers build the whole order — the adhesive and anything the subfloor needs — with the delivered total beside it.
The subfloor
What goes under it
Sound, dry screed or concrete
R848 goes straight down.
If needed · Primer · dusty or absorbent subfloor
D501 Primer 5 L
One coat, about 150 g/m² (more on rough or porous subfloors). Binds dust and reduces absorbency on screed, chipboard and OSB. Glue after 1–2 h. Not a moisture barrier.
£27.00£32.40
about 33 m² at 150 g/m²
Nothing else needed — Bona: a primer is not normally required. D501 only if the surface is dusty or very thirsty.
Damp cement screed or concrete
Barrier
Moisture barrier · silane
R590 DPM 8 kg
One trowelled coat, about 500 g/m² with a Bona 500F trowel. Up to 5 CM-% / 95% RH on cement screed or concrete. Glue after 4–6 h. Not classified as hazardous.
£182.00£218.40
about 16 m² as a barrier
Moisture barrier · polyurethane
R540 DPM 6 kg
Two rolled coats, 250–350 g/m² in total, the second within 24 h of the first. Up to 5 CM-% / 95% RH on cement screed or concrete. Glue after 24 h; lay the floor within 48 h. Contains isocyanates: the user needs diisocyanate training.
£140.00£168.00
17–24 m² as a barrier
A structural DPM must already be in place. R848 can also hold back residual moisture on its own, spread at 2,000–2,200 g/m² with a Bona Trowel Plus on cement screed or concrete, never on levelling compound or gypsum screed. Above 95% RH, rising damp or no DPM: no Bona product is designed for it.
Uneven screed — level it first
Primer · before levelling compound
D515 MultiPrime 10 kg
Diluted 1:1 to 1:3 on absorbent screed, under H600. Bona: do not apply silane adhesive straight onto D515 — the compound goes between.
£125.00£150.00
about 67–250 m² (40–150 g/m² of concentrate)
Levelling compound
H600 Levelling Compound 25 kg
Rapid-set cement compound, 1–20 mm in one pass. At least 2 mm under wood. Ready for wood in about 24 h.
£45.04£54.05
about 9 m² at 2 mm
At least 2 mm of compound everywhere. R848 goes onto the compound, never straight onto D515.
Hairline cracks or old parquet
Decoupling fleece
U310 Polyester Fleece 1 mm · 50 m² roll
Polyester fleece, 0.8 mm (sold as 1 mm). Bonded with the same adhesive as the floor, using an 850F trowel (1000F on coarse or uneven subfloors). Bridges hairline and shrinkage cracks up to 0.5 mm in mineral subfloors; also over old parquet. Suits underfloor heating.
£137.14£164.57
50 m²
Cracks up to 0.5 mm in mineral subfloors. Wider or moving cracks are repaired before anything is laid.
Anhydrite (calcium sulphate) screed
R848 goes straight down.
If needed · Primer · dusty or absorbent subfloor
D501 Primer 5 L
One coat, about 150 g/m² (more on rough or porous subfloors). Binds dust and reduces absorbency on screed, chipboard and OSB. Glue after 1–2 h. Not a moisture barrier.
£27.00£32.40
about 33 m² at 150 g/m²
Must be dry with the laitance removed. No Bona moisture barrier is approved on anhydrite.
