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 Hardwall, a quick-drying undercoat plaster, formulated for medium to high suction masonry backgrounds including bricks, aircrete blocks, and medium-density blockwork.

It can be applied by hand or with a mechanical plastering machine, offering flexibility on site and supporting faster application where required. 

Once set, it provides a durable, high-impact undercoat that is ideal for finishing with British Gypsum Thistle plasters.

It also offers higher-than-normal resistance to efflorescence, reducing the risk of salt deposits forming on the surface. Its robust formulation delivers a strong base coat with excellent adhesion and long-term reliability.

Features & Benefits

  • Quick-drying undercoat plaster: Designed for medium to high suction backgrounds.
  • Durable base: Forms a strong, impact-resistant foundation for Thistle finishing plasters.
  • Efflorescence resistance: Higher protection against salt deposits than standard undercoats.
  • Flexible application: Can be applied by hand or with spray machine for increased speed.
  • Trusted brand: Manufactured by British Gypsum for consistent quality and performance.
  • High impact resistance: Withstands knocks and everyday wear in busy environments.


Applications

  • Masonry backgrounds: Suitable for aircrete blocks, common bricks, medium-density blocks, and dense blocks (excluding smooth low-suction types).
  • Base coat: Provides a strong, reliable undercoat for finishing plasters across internal walls.
  • Hand or machine application: Ideal for plasterers working on both small-scale and large projects.

Installation Guidance

  • Background preparation: Ensure surfaces are sound, clean, and of medium to high suction. Avoid smooth, low-suction blocks.
  • Mixing: Use clean water and follow British Gypsum guidelines to achieve the correct consistency.
  • Application: Apply by hand or mechanical spray machine, then rule and darby to level.
  • Finishing: Once set, over-skim with British Gypsum finishing plasters such as Thistle MultiFinish.

Compliance & Performance

  • Manufacturer: British Gypsum.
  • Product type: Gypsum undercoat plaster.
  • Performance: Quick drying, high impact resistance, and efflorescence protection.
