Product story

The Professional's Choice: Mapei S1 Standard Set White

Take the stress out of complex tiling projects with Mapei S1 Standard Set Flexible Adhesive—a premium white adhesive offering extended working times and superior hold.

Unlike "Rapid Set" adhesives which cure in minutes, this Standard Set formula gives you a generous pot life of up to 8 hours. This makes it the ideal choice for intricate layouts (like herringbone or mosaics), large format tiles that require back-buttering, or simply for DIYers who want the time to get their levels perfect. The White colour is essential when installing light-coloured natural stone (like marble or limestone) or glass, preventing the shadowing that can occur with grey adhesives.


Samples

Want to check it before ordering? An online sample option is not currently attached to this product. Call our Ascot team on 01344 620211 and we’ll check the best sample option for this exact product.

Delivery

In-stock orders are dispatched within 3–5 working days, with express options available. Special-order and made-to-order ranges carry their own lead time, shown on the product page and confirmed when you order. Pallet, slab, large-format and bathware orders travel on a specialist off-load service — we confirm the timescale and book a date that suits you before dispatch.

Delivery is calculated at checkout from your order and postcode (we do not offer showroom collection) and UK delivery is free on orders over £1,000 on most ranges. For pallet deliveries please tell us about access issues in advance — low trees or bridges, narrow roads or gateways, gravel drives, or no turning or unloading space — as a re-delivery charge may apply if we cannot complete delivery.

When your order arrives

Please check your delivery as soon as it arrives. Once goods are unloaded they become the responsibility of the receiver, so if anything isn’t right, contact us within three working days and we’ll put it right quickly.

Returns

Unused, complete orders can be returned within 14 days of delivery; as tiles are picked and packed to your quantity, a restocking fee of 20–30% applies depending on the range. Fired Earth ranges are returned through Fired Earth’s own returns process, and special-order items are non-returnable unless damaged on delivery or faulty. Ordering a free sample first is the simplest way to avoid a return.

Product Frequently Asked Questions

Why should I use White adhesive instead of Grey?

Use White adhesive if you are installing light-coloured natural stone (marble, limestone, travertine), glass tiles, or if you plan to use a light-coloured grout. Grey adhesive can sometimes "shadow" through pale translucent tiles or stain light grout joints during installation.

What does "S1" mean?

"S1" is a European Standard classification for Deformability. It means the adhesive is flexible enough to withstand deflection (bending) of at least 2.5mm. This is crucial for tiling onto timber floors or over underfloor heating where surfaces expand and contract.

Can I walk on it immediately?

No. Because this is a Standard Set adhesive, it takes longer to cure than Rapid Set. You typically need to wait 24 hours before walking on the floor or grouting.

Is it waterproof?

Yes, once cured, it is water-resistant and frost-resistant, making it suitable for bathrooms, wet rooms, and even swimming pools.

Why buy from Hyperion Tiles?

We are an authorized Mapei retailer. We ensure our stock is stored correctly (powder adhesive has a shelf life) and can advise on the perfect primer and grout to complete your system.

Installation & Care Tips

⚠️ Installation & care

  • Priming: Always prime your substrate (plaster, screed, or timber) with an appropriate acrylic primer (like Mapei Primer G) before tiling to ensure a strong bond and prevent the adhesive drying too fast.
  • Back Buttering: For large format tiles (>30x30cm) and natural stone, always apply adhesive to the back of the tile as well as the floor to achieve 100% coverage.
  • Mixing: Mix with clean water to a smooth, lump-free consistency. Let it "slake" (rest) for a few minutes, then mix again before use.
  • Moisture Sensitive Stone: If installing Green Marble or certain resin-agglomerates, please check with us first, as you may require a rapid-setting adhesive (S1 Rapid) to prevent warping.
