Joins & Extras – Frequently Asked Questions – 6th December FAQs

In this feature we will look at some of the most commonly asked questions among the hundreds of homeowners and trade customers whom we deal with on a weekly basis.

Why have I got more joins than I planned for?

During your template visit, our templaters will check the access and layout of the kitchen. Often at this stage, additional joins may prove to be essential to safely maneuver your worktops into position. During the visit, you should be asked to review any changes as part of our Template Checklist procedure.

Why can I see my join on a solid surface product, which should have been seamless and inconspicuous?

Worktops joins in solid surface should be seamless and inconspicuous. This means there should be no visible glue line from normal viewing distances. Whenever this is not the case, there reason is typically due to one of two potential issues, which depends on your material.

Veined Products

Veined worktops are those which do not have homogenous colouration throughout the surface, such as found in the the Apollo Slab Tech Marmo range. These styles can have swirling patterns, or streaks of colour which essentially means that the material is incapable of ’tiling’ seamlessly. Where products within this category join, you are likely to see an abrupt discontinuation of any patterns on the surface along the line where one section stops and the other one starts.

Perpendicular joins, or L joins may also show a change in direction, particularly for styles where direction is a major characteristic, such as Marmo Mare Gris. This sudden right-angle turn will make the location of joins more obvious, even if the joint itself is not. Where worktops exceed 3m in length (2.5m for 30mm Slab Tech), or 900mm in width, you may also see end-to-end or side-by-side joins, which while not as extreme, will still be visible.

Corian products fabricated at our manufacturing facility are joined with an S-Joint. This style of joining means there will not be an obvious straight line where one section ends and the other begins, which will often make joins themselves less noticable. For Corian, or other solid surface brands which have Lucent colours, a join may still be visible. In these cases, the glue used in joints is opaque, which blocks more light than the worktop itself; resulting in a darker appearance.

Installation Issues

We at Sheridan offer installer training for our modular solid surface products; both at our production facility; and through video guides available on our Youtube channel. While we offer our training freely, we sometimes encounter issues where correct process hasn’t been followed – resulting in visible joins. These include:-

  • Edges not cut to an exact fit – When this occurs, a join may be have an angled or uneven appearance, exposing the glue line. Many factors can cause this to happen, such as uneven tooling or walls. To avoid this happening, a dry-fit should always be performed before adhesive is used.
  • Joining faces not sufficiently cleaned – When the adhesive used to join worktops is contaminated, it can cause discolouration which results in a more obvious, dark-line joint between worktop sections. We provide IPA wipes with our installation kits to fully clean any connecting faces before adhesive is used.
  • Join is excessively wide – The join itself should be so thin as to be almost imperceptible. Essentially, the glue used should only function as a binding agent, and not as a filler for the gap between the two worktop sections. Correct use of G-clamps or suction cups should ensure that the worktops are held together tightly during the entire curing process; which prevents this issue from occurring.
  • Incorrect glue – This issue is often misdiagnosed. While the glue variants provided for use with specific materials are designed to be discreet, they are not exact colour matches. Essentially, the glue-line itself should be so thin that as long as the colour is roughly the same tone as the worktop; the join should be invisible at normal viewing distances. If you think the right glue might not have been used, you can check the recommended colours in the consumables > Apollo Solid Surface Adhesive section of our website.

How long are the standard draining grooves?

Draining grooves vary by material. for Timber and Solid Surface Materials, these are 480mm in length. Natural and engineered stone worktops’ drainer grooves are comparatively shorter, at 400mm in length.

Can you apply a Sharknose profile to 20mm Slab Tech?

Yes this is available. A full list of edge details, cutouts, styles, bands and finishes can be found in our Retail Price List. You can request a hard copy of our latest brochure here.
