How delivery works

We work with a nationwide network of trusted suppliers. Items in your basket may be supplied by different suppliers and delivered separately. Where this applies, you will see delivery charges shown at checkout for each part of your order. We always aim to group products from the same supplier to keep delivery costs as low as possible.

Delivery areas

Delivery charges apply to mainland UK, excluding: AB, CA, CF, DD, DG, EH, EX, FK, KA, KW, KY, IV, LA, LD, LL, ML, NP, PA, PH, PL, SA, SY, TR, TQ and TD.

If your address is in one of these areas, we will contact you before processing your order to confirm any additional costs. We do not currently offer delivery outside the UK mainland.

What to expect on delivery day

  • Deliveries are typically kerbside.
  • Please ensure someone is on-site to accept delivery. For heavier items, help with offloading may be required.
  • Many building materials arrive on large vehicles. If access is restricted, a specialist vehicle such as a HIAB may be required and could incur an additional charge.

Why delivery can cost more than typical parcel delivery

Building materials often travel on larger vehicles and usually carry fewer drops per run than parcel networks. That is why delivery charges can be higher than standard e-commerce shipping.

Returns

Returns depend on what you have bought and whether there is anything wrong with it. For full details on eligibility, timeframes, and exclusions, please see our full policy.

Product Overview

British Gypsum Thistle Bonding Coat, a multi-purpose undercoat plaster formulated for smooth or low suction backgrounds including dense blockwork, concrete, tiling, plasterboard, and surfaces pre-treated with Thistle Bond-it.


Supplied as a pre-mixed gypsum plaster with exfoliated vermiculite aggregate, it only requires the addition of clean water, making it quick and simple to prepare on site.

Its fine, lightweight mix delivers excellent workability, ensuring reliable performance when spreading, ruling, or darbying. The result is a durable, level undercoat that provides a strong, hard-wearing base for British Gypsum finishing plasters, producing a surface ready for decoration.

It can be applied directly to plasterboard where dubbing out is needed, or used in refurbishment projects to restore and level existing internal walls and ceilings.


Features & Benefits

  • Durable base: Provides a strong, hard-wearing undercoat for decorative finishes.
  • Low suction backgrounds: Suitable for use on plasterboard, dense blocks, concrete, and tiled surfaces.
  • Versatile undercoat: Works across new-build and refurbishment projects.
  • Direct to plasterboard: Can be applied where dubbing out is required.
  • Fine mix formulation: Delivers smooth application, reliable workability, and consistent results.
  • Easy preparation: Only requires the addition of clean water before use.
  • System compatibility: Forms an ideal base for finishing plasters such as Thistle MultiFinish.

Applications

  • Undercoat plaster: Provides a reliable base for skimming with British Gypsum finishing plasters.

  • Wall and ceiling renewal: Applied as part of refurbishment projects to level and restore old surfaces.
  • Plasterboard dubbing out: Levels irregular surfaces before finishing.

Installation Guidance

  • Background preparation: Ensure substrates are sound, clean, and suitably pre-treated where required (e.g. Thistle Bond-it on painted or very smooth surfaces).
  • Mixing: Add clean water to the pre-mixed plaster and blend to achieve a smooth, workable consistency.
  • Application: Spread evenly, rule to level, and finish with a darby before applying finishing plaster.
  • Setting time: Work within the recommended period to avoid premature stiffening.
