Stixall is one of the adhesive sealants sold at Sealants4All for jobs around a caravan or motorhome where you want one cartridge that both bonds and seals. This guide sets out what the Sika Stixall Adhesive & Sealant product page says the product is for, which bonding and sealing jobs on a caravan or motorhome it names, and how it compares on paper with two other adhesive sealants on the site. Every product statement below is taken from that product’s own page or, for Sikaflex 221, from the Sika data sheet; where a figure is not given on the page or data sheet, this guide does not give one either.
What Sika Stixall Adhesive & Sealant Is
The product page describes Sika Stixall Adhesive & Sealant as a product for sealing and bonding, supplied as a 290 ml plastic cartridge. Its properties, as the page gives them, are initial grab, no slip and gap filling, and it can be applied to wet surfaces. The page also says the product gives primerless adhesion to most surfaces, naming metals, most plastics, glass, concrete, plaster, plasterboard, polyester, acrylic, wood, enamel and painted surfaces.
What the page does not give is any figure: it states no skin time, no cure time, no application or service temperature range and no shelf life, and it does not name the product’s chemistry. For those values you need the manufacturer’s data sheet, which this guide does not reproduce. If a job depends on a cure time or a temperature limit, read the data sheet before you start rather than assuming the product behaves like another adhesive sealant you have used.
Interior Adhesive and Sealant, Exterior Adhesive
One line on the product page matters more than the rest for a caravan or motorhome: the product is “for interior (adhesive/sealant) and exterior (adhesive) use”. The page states that distinction without explaining it, and this guide repeats it as written. In practice it means you should read the product page and data sheet before using Stixall as the only seal on an exterior joint, and treat its exterior role as bonding unless the data sheet says otherwise.
The Cartridge and the Gun
Stixall comes as a 290 ml cartridge, so you need a cartridge gun. The S4ALL PRO Caulking Gun for Sealant Cartridges applies sealants and adhesives from standard cartridges; its page describes a metal push rod and trigger for even, controlled beads and a thumb release to stop the flow between beads. The method on its page applies to any standard cartridge: press the thumb release and pull the rod fully back, open the cartridge, fit the nozzle and cut it at an angle to the bead size you need, load the cartridge, squeeze the trigger steadily as you move along the joint, and press the thumb release when you stop so the material stops flowing. Surface preparation, open time and curing are product-specific, so for those steps follow the product you are using, not this guide.
Bonding Jobs on a Caravan or Motorhome Where Stixall Fits
The product page names four uses. Three of them are bonding jobs, and all three come up in caravan and motorhome maintenance: a nail replacement adhesive, bonding mirrors, and jointing cladding panels. The fourth, perimeter pointing, is a sealing job and is covered in the next section.
Nail Replacement Adhesive, Even on Damp Surfaces
The page describes Stixall “as a nail replacement adhesive, even to damp surfaces”. Inside a caravan or motorhome this is the kind of fixing where you do not want screws showing or do not want to drill into a thin panel: a batten, a trim strip, a small bracket or a fitting that a few screws would otherwise hold. The page’s surface list covers the materials most of these fixings meet, such as wood, plastics, plasterboard and painted surfaces, and its note on damp surfaces means a wiped-down interior panel does not have to be bone dry before you start.
Where the part is light and you only need to hold it in place, a tape may do the job with no curing time. The post Strong Double-Sided Tape vs Adhesive Sealant: When to Use Which explains where the line falls, so this guide does not repeat it.
Mirrors, Trims and Cladding Panels
“Bonding mirrors to most common substrates” is the second use the page gives. A mirror in a caravan washroom or wardrobe door is a typical case: the page’s surface list includes glass, and no slip is one of the properties the page gives, which is the property a mirror needs while the adhesive cures.
“Jointing cladding panels” is the third use. On a caravan or motorhome, interior wall boards, shower-area panels and the trims that cover their joints are the obvious candidates. The page’s gap filling property means the adhesive can take up a small gap between a panel edge and its trim rather than needing a perfectly flush joint. The page does not say that Stixall is for bonding exterior body panels, roof fittings or solar panels, so this guide makes no claim for those jobs; for bonding large components on a vehicle the site sells other Sika products, and the caravan sealants category gathers them.
Sealing Jobs: Perimeter Pointing Around Doors and Windows, and Interior Joints
The sealing use the product page names is “perimeter pointing around doors and windows, especially in mobile structures such as caravans”. Perimeter pointing is the bead of sealant run around the outside edge of a frame where it meets the surrounding panel. Taken together with the page’s interior and exterior line, Stixall is described as an adhesive and sealant indoors and as an adhesive outdoors, so read the product page and data sheet before relying on it as the sealant in an exterior frame joint, and follow what they say.
Indoors, the same gap filling and no slip properties apply to joints around a shower tray, a worktop upstand, a washroom panel or an internal door frame, where the bead has to stay put on a vertical surface while it cures. Choosing and applying a caravan window sealant is its own subject; the post Caravan Window Sealant: How to Choose and Apply the Right Product covers it, and this guide does not.
Overpainting the Finished Joint
The page states that Stixall is “overpaintable if required (with water based paints – test an inconspicuous area before use)”. For an interior bead that will be painted to match a panel, that is the instruction to follow: a water based paint, and a test patch first. The page gives no waiting time before painting, so take it from the data sheet or test on a scrap bead.
Stixall, Sikaflex 221 and Soudal Fix All High Tack: What Each Product Page States
Sealants4All sells two other adhesive sealants that can be set next to Stixall. This section sets the three side by side using only what each product page or data sheet states; it does not rank them.

Sikaflex 221 Data-Sheet Values
Sikaflex 221 Strong Adhesive Sealant – Multi-Purpose Application – Black – 300ml is the one product of the three with values this guide can quote, because the Sika data sheet (Sikaflex-221 PDS v05.01, 03-2026) is held on file. Sika describes it as a multi-purpose, 1-component polyurethane adhesive/sealant that is moisture-curing, bonds well to metals, metal primers and paint coatings (2-component systems), ceramic materials and plastics, and is suitable for making permanent elastic seals.
| Property (Sikaflex 221) | Value |
|---|---|
| Chemical base | 1-component polyurethane |
| Cure mechanism | Moisture-curing |
| Skin time | 60 minutes at 23 °C / 50 % relative humidity |
| Application temperature (ambient) | 5 °C to 40 °C |
| Service temperature (long-term) | -50 °C to 90 °C |
| Shelf life | 12 months, stored below 25 °C |
| Colours (data sheet) | White, grey, black, brown |
Source: Sika Product Data Sheet Sikaflex-221, version 05.01 (03-2026). The data sheet gives full cure as a curing diagram, not a single figure, so no full cure time is quoted here. For the jobs Sikaflex 221 is used for on a caravan, see What Is Sikaflex 221 Used For? 10 Real-World Applications.
Soudal Fix All High Tack
The Soudal 101444 Fix All High Tack Super Strong Adhesive White product page describes it as a hybrid polymer adhesive and sealant with immediate grab that allows many materials to be bonded vertically without the need for temporary support. The page says it can be applied to dry or slightly damp substrates, is paintable with most water-based paint systems once cured, and names panels, skirting boards, profiles, wall cladding and decorative elements among the things it fixes. As with Stixall, no data sheet for it is held on file, so this guide gives no figure for it.
In short: Stixall’s page names damp-surface fixing, mirrors, cladding panels and perimeter pointing; Sikaflex 221’s data sheet gives the polyurethane values in the table; Fix All High Tack’s page emphasises grab for vertical bonding. Which one suits a given job depends on the surface, whether the joint is interior or exterior, and whether you need the bead to seal as well as bond, so match the job to the product page rather than to a general preference.
