Starx 515 & 515 Max Tile Adhesive for Wall and Floor

A Dependable, Premixed Solution for Ceramic & Vitrified Tile Fixing

Last updated: 22 September 2026 · Reviewed by the Starx Product technical team

Starx 515 & 515 Max is a cement-based tile adhesive for wall and floor use, formulated for fixing ceramic and vitrified tiles on internal surfaces, with one 20kg bag covering 55–60 sq ft.

Starx 515 & 515 Max is a premixed, single-pack tile adhesive for wall and floor made from cement, high-grade polymers, natural minerals and selected aggregates, built for fixing ceramic and vitrified tiles on interior surfaces. Once mixed with water, it stays workable for up to an hour and sets fully within 24 hours at 30°C ambient, though this can shift slightly with humidity, temperature or airflow on site. One 20kg bag covers approximately 55–60 sq ft when applied with a 1/4" × 1/4" (6mm × 6mm) square-notch trowel at a 3mm bed thickness, and it bonds well with cement mortar beds, cement plaster and cement terrazzo. It requires no separate additives and can be applied by ordinary site labour with standard tools — no specialised training needed.

Why It Works So Well

Built for fixing ceramic and vitrified tiles with confidence, this adhesive bonds far more securely than the old-school sand-cement method, so you don't end up dealing with hollow spots, cracked tiles, or tiles coming loose after a few months.

Where You Can Use It

Meant for internal floor and wall tiling work — think homes, offices, showrooms, hotel interiors, and pretty much any indoor space where you need something you can rely on.

Surfaces It Sticks To

Use it on cement mortar beds, cement plaster, and cement terrazzo — the surfaces you'll come across on most construction sites.

How Far a Bag Goes

One 20 kg bag typically covers 55–60 sq ft when applied with a 1/4" × 1/4" (6mm × 6mm) square-notch trowel at a 3 mm bed thickness. That means less material wasted and a better return on every bag.

Why Builders Choose Starx as Their Adhesive Manufacturer

Builders, contractors, and homeowners keep choosing this adhesive for their interior tiling work because it simply performs — batch after batch, project after project.

Polymer-Enriched Formula

Our 515 & 515 Max is loaded with carefully chosen polymers that boost flexibility, water resistance, and long-term bond strength — which is exactly why it's held up as one of the more dependable choices on the market.

One Adhesive, Both Surfaces

A lot of adhesives are made for the floor alone. This one bonds equally well on vertical and horizontal surfaces, so you don't need to buy or stock two separate products for one tiling job.

Enough Time, Then a Quick Set

You get roughly an hour of working time after mixing to get the alignment right, and it's fully set within 24 hours at 30°C — quick enough to keep the project moving without cutting corners on the bond.

No Special Skills Needed

You don't need a specialist crew to apply it. Ordinary site labour can mix and lay this adhesive with standard tools, which keeps both the cost and the timeline of the job in check.

No Hollow Spots, No Debonding

The strong adhesion this formula offers means you won't be dealing with hollow tiles, lifting edges, or debonding a few months down the line — just a wall and floor surface that stays put.

A Manufacturer You Can Rely On

Starx Product is a leading Adhesive Manufacturer, and every 20kg bag of our 515 & 515 Max goes through the same consistent quality checks before it reaches contractors and homeowners.

Manufactured In-House

515 Tile Adhesive for Wall and Floor vs the Old Sand-Cement Method

Sand-cement mortar has been the go-to for tile fixing for decades, but it comes with its own headaches. We designed the 515 & 515 Max to fix exactly those problems. Here's what changes when you switch:

  • A Stronger Grip: The polymer content in this adhesive bonds far better than plain cement-sand mortar, so you see a lot less tile hollowing over time.
  • One Product for Wall and Floor: One bag handles both vertical and horizontal surfaces, unlike mortar mixes made for just one.
  • Quicker Turnaround: It sets in 24 hours and doesn't need water curing, which shaves real time off the project compared to old thick-bed methods.
  • The Same Result Every Time: Because it's factory-made, every bag gives you the same mix ratio and performance — something hand-mixed mortar just can't guarantee.
  • Better Value Per Bag: One 20 kg bag covers 55–60 sq ft, which brings down both material and labour cost compared to thick-bed mortar.
  • Nothing Else to Add: Mix it with water and you're ready to go — no extra additives, no guesswork on site.

How to Apply Starx 515 & 515 Max

A quick step-by-step reference for getting the best results with Starx 515 & 515 Max on your interior floor and wall tiling work.

Step Action Details Suitable
1 Get the Surface Ready Clean the surface well — no dust, grease, loose particles or standing water — before you apply the adhesive.
2 Mix It Up Add the 515 adhesive powder to clean water and mix until you get a smooth, lump-free paste. Use it within an hour of mixing.
3 Spread It On Apply the adhesive evenly on the floor or wall using a 6mm × 6mm square-notch trowel to keep the bed thickness at around 3 mm.
4 Set the Tiles Press ceramic or vitrified tiles firmly into the adhesive bed, and use a rubber mallet to make sure they sit evenly with full contact.
5 Fine-Tune the Layout You've got about an hour of pot life to straighten out alignment and spacing before the adhesive starts to set.
6 Let It Set Leave the tiles undisturbed for 24 hours at around 30°C. Keep in mind that temperature, humidity, and wind can shift this timing a bit.
7 Finish with Grouting Once the adhesive has fully set, fill in the tile joints with Starx Tile Grout for a neat, finished look.
— Not for Outdoor Use This 515 & 515 Max grade is meant for internal use only. For outdoor or heavy-duty jobs, go with Starx 525, 535, or 545 instead.

Frequently Asked Questions

A few questions people commonly ask us about the Starx 515 & 515 Max.

What is Starx 515 & 515 Max used for?

It's a premium adhesive made for fixing ceramic and vitrified tiles on interior floors and walls. It works well for homes, offices, hotels, and commercial spaces that need something dependable for internal tiling.

Can I use this on both my walls and my floor?

Yes, that's exactly what it's built for. Unlike adhesives made for floors alone, the 515 & 515 Max works on both, so it's a practical, single-product choice for a full interior tiling job.

How long does it take to set?

At a normal room temperature of around 30°C, it sets within 24 hours. That said, high humidity, lower temperatures, or a bit of wind can push the setting and pot life times slightly.

How much area does a 20 kg bag cover?

A 20 kg bag of the Starx 515 & 515 Max covers roughly 55 to 60 sq ft when you apply it with a 1/4" × 1/4" (6mm × 6mm) square-notch trowel at a 3 mm bed thickness.

What surfaces does it work on?

It bonds well with cement mortar beds, cement plaster, and cement terrazzo — the surfaces you'll typically find in homes and buildings.

Do I need skilled labour to apply it?

Not really. One of the best things about this adhesive is that ordinary site labour can apply it with standard tools — no special training required — which keeps it cost-effective for projects of any size.

Can I use 515 & 515 Max outdoors?

No, this variant is formulated for internal floor and wall tiling only. For exterior or heavy-duty applications, Starx Product also makes 525, 535 and 545 grades built for those conditions.
