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.

Building Control Northern Ireland (the 11 district councils)
NORTHERN IRELAND. The Northern Ireland Building Regulations are made by the Department of Finance and administered by the 11 DISTRICT COUNCILS, so there is no private sector alternative: Northern Ireland has no approved inspectors and no registered building control approvers, and the England route of appointing a private building control body simply does not exist. The page lists the Building Regulations (Northern Ireland) 2012 with the amending regulations of 2014, 2016 and 2022, and links the current and historical Technical Booklets plus the contraventions and appeals route. The regulations are intended to secure the safety, health, welfare and convenience of people in and around buildings and to further the conservation of fuel and energy. The site names all 11 councils including Belfast City, Derry City and Strabane, Lisburn and Castlereagh, Newry Mourne and Down, Mid Ulster and Fermanagh and Omagh.

Department for Business and Trade
The UK regulator a note should name when it says a product has been recalled or is unsafe, rather than pointing at a retailer. Part of the Department for Business and Trade, its stated purpose is to protect people and places from product-related harm so consumers and businesses can buy and sell with confidence. It is the body behind the product recalls and alerts database, and the enforcement authority behind consumer product safety rules covering items a renovation buys, including corded internal blinds, electrical accessories and lighting.

Health and Safety Executive
HSE's construction lead page. It states lead pigments were commonly used in paints for buildings until the 1960s and that lead was not removed from all commonly used paint until the early 1980s, which is the date test any note about stripping paint in an older house needs. The highest-risk activities it names are stripping or preparing leaded paint from doors and windows, working with lead on roofs, hot cutting of lead or leaded paint in demolition, and blast removal of old leaded paint. Health effects include anaemia and kidney disease, with chronic exposure risking kidney, nerve and brain damage, and a link to a small number of occupational cancers. The governing law is the Control of Lead at Work Regulations 2002, which requires employers to protect employees from the risks from lead, applied through an Assess, Control and Review model with FFP3 respiratory protection at an assigned protection factor of 20, changed work methods, dust control, protective clothing, hygiene and medical surveillance.

The figure that governs any dry cutting of a quartz or engineered stone worktop, and the one a fabricator should be asked about. INDG463, published 05/24. The Workplace Exposure Limit for respirable crystalline silica is 0.1 mg per cubic metre of respirable dust averaged over 8 hours, and control measures must be effective in keeping exposure below it. The leaflet tabulates crystalline silica content by material: artificial or engineered stone up to 95 per cent depending on the stone pieces or minerals used, sandstone, gritstone and quartzite above 70 per cent, mortar and concrete 25 to 70 per cent, shale 40 to 60 per cent, china stone up to 50 per cent, granite 20 to 45 per cent and typically 30 per cent, slate 20 to 40 per cent, ironstone up to 15 per cent. Employers must assess the risk, record it in writing where they employ more than five people, consider substituting a lower-silica material, control exposure by engineering means first, supply RPE only where engineering controls cannot do the job, face-fit test tight-fitting RPE on clean-shaven wearers, monitor to confirm the WEL is not exceeded, and arrange health surveillance where appropriate.

Sets the conditions under which work with asbestos does not need a licence. The exposure must be sporadic and of low intensity, with the air concentration not exceeding 0.6 fibres per cubic centimetre measured over 10 minutes, and must not exceed the legal control limit of 0.1 asbestos fibres per cubic centimetre of air averaged over a four hour period. Materials listed as non-licensed include asbestos-containing thermoplastic and vinyl floor tiles worked on without substantial breakage, drilling textured decorative coatings to fit fixtures and fittings, painting or repainting asbestos insulating board in good condition, and maintenance of asbestos cement products such as roof sheeting, tiles and rainwater goods provided they are not substantially damaged. Notifiable non-licensed work includes large-scale removal of textured decorative coatings by steaming or gelling, and removal of asbestos cement where the material will be substantially damaged or broken up. This is the reference for anyone lifting old vinyl floor tiles or stripping Artex in a pre-2000 home.

Scottish Government
The classification table behind every reaction to fire claim on a floor covering, lining or insulation product sold in Scotland. Annex 2.B, Table 2.10, sets out the Euroclasses A1, A2, B, C, D, E and F and the test standards that produce them: A1 requires BS EN ISO 1182:2020 non-combustibility and BS EN ISO 1716:2018 gross heat of combustion; A2 requires BS EN ISO 1182:2020 or BS EN ISO 1716:2018 together with BS EN 13823:2020 the single burning item test; B, C and D require BS EN 13823:2020 with BS EN ISO 11925-2:2020 ignitability; E requires BS EN ISO 11925-2:2020 alone; F is no performance determined. The additional classifications differ by class: smoke production, the s1 to s3 suffix, and flaming droplets or particles, the d0 to d2 suffix, both apply to classes A2 to D, while classes E and F carry only the flaming droplets and particles classification. Note that floorings are classified on the same letters with an fl subscript, for example Cfl-s1, using the radiant panel test rather than the single burning item, so a product's wall class and its floor class are not interchangeable.

The 714-page handbook that carries Scotland's own numbers, which differ from England's. Table 4.3 sets private stair geometry at minimum rise 100 mm, maximum rise 220 mm, minimum going 225 mm, tread not less than the going and maximum pitch 42 degrees; Table 4.4 sets any other stair at maximum rise 170 mm, minimum going 250 mm and maximum pitch 34 degrees; going plus twice the rise must be between 550 mm and 700 mm, tapered treads at least 50 mm at the narrow end, a flight generally 3 to 16 rises. Table 4.5 puts effective width at 900 mm for a private stair, 800 mm where a continuous handrail is on both sides, 600 mm where it serves only sanitary accommodation or one room, and 1.0 m for any other stair, with stringer or newel projection no more than 30 mm. Clause 4.3.15 sets handrail height at 840 mm to 1.0 m above the pitch line, 4.3.16 headroom at 2.0 m, and 4.3.17 points spiral and helical stairs to BS 5395-2:1984. Table 5.1 sets separating element performance at 56 dB DnT,w airborne and 56 dB L'nT,w impact for new build, relaxed to 53 dB and 58 dB for conversions of traditional buildings.

Scottish Government (gov.scot)
Scotland's equivalent of the Approved Documents, and the reason a note that quotes only English rules is wrong for a fifth of the UK. This edition is in force from 6 April 2026 and applies to building warrants submitted on or after that date and to work not requiring a warrant commenced from that date. It gives guidance on achieving the standards set in the Building (Scotland) Regulations 2004, arranged in sections rather than parts: section 3 environment (ventilation, drainage, condensation), section 4 safety (electrical safety and installations, glazing and danger from accidents, including clause 4.13 which invokes PAS 24 for security), section 6 energy (U-values for windows and doors) and section 7 sustainability. Scotland uses a building warrant and a completion certificate rather than a building notice, and has no Part P competent person scheme equivalent, so electrical work is covered by the warrant system instead.

The National Archives (legislation.gov.uk)
SI 1988/1324, the flammability regime that applies to the soft furnishings and any loose upholstered elements a fitted-furniture project buys in. It revoked the Upholstered Furniture (Safety) Regulations 1980 and its 1983 amendment and imposes requirements on new domestic furniture, including garden furniture that may be used indoors and furniture for use in caravans, subject to exceptions for certain furniture. Some requirements also apply to second-hand furniture, and the regulations do not apply to goods for export. The point for a note is that these regulations bite on furniture supplied in the course of a business, not on the building fabric.
