Bitumen primer price
Published · Updated
Bitumen primer is sold by the bucket, in 20 kg or 20 L tins, and the useful figure is the price per square metre it treats. JUYONS asks for 0.3 kg of primer per m² under its membranes, so a 20 kg bucket covers about 66 m² — our calculation, 20 ÷ 0.3.

Kitovu price for a 20 kg bucket of bitumen primer
The figure in the price panel is the bitumen primer price Kitovu charges per bucket for the Water-Based Bitumen Primer for Waterproofing Membranes. JUYONS, a waterproofing maker in Hubei, China, sells it in a 20 kg bucket labelled “Bitumen Membrane Primer” (code JY-JCCLJ). Inside is a water-borne bitumen emulsion, modified with polymer, that is rolled or brushed onto the deck before a bitumen sheet goes down. Kitovu keeps it in stock in Zanzibar; the card lists the full specification.
Listed bitumen primer prices
Only one Tanzanian shop showed a primer price on its own page on 12 November 2026. Its tin is measured in litres, Kitovu’s in kilograms, so the two are not the same quantity.

How far one bucket goes
JUYONS sets the priming rate under its membranes at 0.3 kg for every square metre, rolled or brushed. One 20 kg bucket of the water-based bitumen primer therefore covers about 66 m² of deck or wall — 20 divided by 0.3 gives 66.7, by our arithmetic. A flat roof of 10 × 12 m, 120 m², takes two buckets (120 ÷ 66.7 = 1.8, rounded up).
A solvent primer is counted in litres instead. Sika sells its SikaShield Primer S-30 IN in a 20 L drum and gives 0.25–0.40 L/m² per coat, so one drum treats 50–80 m² per coat (our calculation: 20 ÷ 0.40 and 20 ÷ 0.25). Sika states a shelf life of 12 months for it; JUYONS gives 6 months for its primer, so ask for the production date along with the price.
The maker also states:
- Drying. 2–3 hours at normal temperature, until fully dry, before the membrane is laid.
- Application. Brush, roller or spray; corners, joints and pipe roots first.
- Storage. A dry, cool, ventilated place at 5–35°C, out of rain, sun and frost; shelf life 6 months.
What changes the price of bitumen primer
- Water or solvent. Primers come as water-based emulsions or as bitumen cut back in solvent. They dry differently and are handled differently: JUYONS lists its water-based primer as non-flammable and non-explosive, while Sika gives a flash point of 30°C or more for its solvent primer. Compare like with like; the bitumen primer page sets out both kinds.
- Kilograms or litres. A 20 kg bucket and a 20 L tin hold different amounts of primer unless the seller gives the density. Ask for the weight or the coverage per m², not just the tin size.
- Coverage, not tin price. Two primers at the same tin price can cost differently per m² if their makers set different consumption rates.
How to order
Work out the area to be primed in m², divide by the coverage of one bucket, and round up. Then send the area on WhatsApp and name the water-based primer; the primer goes under a sheet such as the APP rolls on the APP membrane price page. Other price pages are listed under prices in Tanzania.
