Siniat
Manufacturer datasheet for standard drylining plasterboard. A 2400 x 1200mm sheet weighs 17.3 kg at 9.5mm, 23.0 kg at 12.5mm and 28.8 kg at 15.0mm, equivalent to 6.0, 8.0 and 10.0 kg/m2, which is why a 12.5mm 8 by 4 sheet is a two person carry up a staircase. Thermal conductivity is 0.19 W/mK, giving a thermal resistance of 0.050 m2K/W at 9.5mm, 0.066 at 12.5mm and 0.079 at 15.0mm, so plasterboard contributes almost nothing to a wall U-value on its own. Reaction to fire is Euroclass A2-s1, d0. The core is aerated calcium sulphate di-hydrate between paper liners with a tapered edge for jointing. Transversal breaking load is at least 160N. Fixings are self drilling screws for metal up to 0.7mm and heavier screws for metal up to 2.5mm, or GTEC High Thread Screws into timber.

Soudal
Manufacturer technical data for a hybrid polymer adhesive sealant. Skin formation at 23C and 50 per cent relative humidity is about 10 minutes and curing speed is 2 to 3 mm per 24 hours, so a 10mm deep joint takes several days to cure through. Hardness is 40 plus or minus 5 Shore A with elongation at break of 750 per cent. The joint design rules are minimum 2 mm and maximum 10 mm width for bonding, and for joints minimum 5 mm and maximum 30 mm width with a minimum 5 mm depth. It can be painted with water based systems and is EC1+ certified for very low emission. Shelf life is 15 months in unopened packaging stored cool between +5C and +25C. Soudal warns that a total absence of UV can cause a colour change in the sealant, and that where different reactive sealants meet, the first must be completely hardened before the next is applied.

Soudal
Manufacturer technical data for a high initial grab hybrid polymer adhesive. Skin formation at 23C and 50 per cent relative humidity is about 5 minutes, half that of the flexible grade, and curing speed is 3 mm per 24 hours. Hardness is 65 plus or minus 5 Shore A with elongation at break of 400 per cent, so it is markedly harder and less elastic than the flexible grade, which is the trade-off between an adhesive and a movement joint sealant. Joint design is minimum 2 mm and maximum 10 mm width for bonding, and minimum 5 mm to maximum 30 mm width with 5 mm minimum depth for joints. It is impervious to mould and can be painted with water based systems. Shelf life is 15 months unopened between +5C and +25C. Soudal notes it can only be used on the bottom of natural stone tiles and not as a joint sealant on that surface.

Soudal UK
Soudal UK technical datasheet for Fix ALL TurboTack, master code 9902051, revision 08-05-2026. This is the sheet that gives the number a grab adhesive note needs: 'Extreme high initial tack of min. 200 kg/m2', listed again in the technical data table as Initial tack > 200 kg/m2. That is about 2 kg held by a 100 cm2 patch of adhesive, which is an order of magnitude below the 70 to 150 N per 100 cm2 figures repeated in DIY guidance. Base is SMX hybrid polymer, moisture curing. Skin formation ca. 5 minutes, curing speed ca. 3 mm per 24 hours, so cure is a depth per day and a deep bead takes days. Hardness 70 plus or minus 5 Shore A. Elasticity modulus ca. 2.80 N/mm2 and maximum tension ca. 3.60 N/mm2 to ISO 37. Maximum allowed joint movement plus or minus 20 per cent. Application temperature +5C to +35C, temperature resistance -40C to +90C. It achieves a hand tight bond in 30 minutes and is non staining on natural stone.
