Description
The Atlas GTA 5kg tub holds the same extra-white polymer finish as the trade-size 18 kg tub, in a pack sized for a repair, a single ceiling or a run of plasterboard joints. Open it, stir it and it is ready: it tapes joints, fills shallow dents up to 3 mm and gives a smooth, white skim indoors. Five kilograms skims about 5 m² once, or tapes about 10 m of joint.
When Atlas GTA 5kg Is the Right Size
Coverage is the simplest way to choose. Atlas puts consumption at about 1.0 kg per m² for every coat and about 0.5 kg per metre of taped joint. That gives:
- Atlas GTA 5kg — about 5 m² per coat, or about 10 m of joint: a patched wall, a box-in, a small room's joints.
- 18 kg tub — about 18 m² per coat, or about 36 m of joint: whole rooms and full skims.
A two-coat skim doubles the amount, so a 2.5 m² patch twice over uses about one 5 kg tub.
Why It Suits Small Jobs
- Nothing to mix. It is a ready mass of resin binders and fine white mineral fillers — no powder, no water to measure.
- One product for tape and finish. Atlas classes it as a dual-purpose joint compound, so the same tub beds the tape, covers the screw heads and skims the board.
- Smooth on the first pass. The fine white fillers leave a surface that needs little correction before sanding.
- A clean finish indoors. Once hard, it can be misted and rubbed smooth with a sponge float instead of dry sanding.

Using It, Step by Step
- Make sure the wall is dry, sound and free of dust, grease and loose paint. Prime a very absorbent surface with Atlas Uni-Grunt; other options are in primers.
- Stir the mass until even. Liquid on the top after storage is normal.
- For joints, fill the gap, bed the tape without folds and cover it thinly.
- Apply the skim with a stainless steel trowel or a roller of 11 mm pile or longer, no more than 3 mm thick. Trowels and spatulas are in skimming blades and spatulas.
- Lay the next coat once the first turns dull and slightly damp, about two hours at 20 °C.
- Sand with 150–220 grit when fully dry, dust off and prime before painting.
Keep the room between +5 °C and +25 °C while you work with Atlas GTA 5kg. If you are skimming a large area by roller in one go, compare Atlas GO! 25 kg bucket.
Standards
Atlas GTA meets EN 15824:2017 and EN 13963 (type 3A joint compound), with Declaration of Performance No. 175/2/CPR and fire class A1. The technical sheet is shared with the 18 kg tub.
Ordering and Collection
Renders World sends orders the same day when the tub is in stock, and parcels up to 25 kg can go next day after the team confirms the delivery option — every delivery is kerbside. You can also collect Atlas GTA 5kg from the Renders World counter at Unit 9A, Central Trading Estate, Southampton SO14 5JP. Tubs bought from Renders World come back in their original condition within 14 days under the returns policy. More finishes are in top coat plasters and fillers.
Atlas GTA 5 kg: Common Questions
Is the 5 kg tub the same as the 18 kg tub?
Yes — the same Atlas GTA polymer finish, the same figures and the same uses. Only the pack size differs.
How much will one 5 kg tub do?
About 5 m² for one coat, about 2.5 m² for two coats, or about 10 m of taped joint.
Can I keep an opened tub?
Yes, if nothing has been mixed into it. Cover the surface with foil, close the lid tight, store it between +5 °C and +35 °C and use it within 12 months of production.
Can I use it on a ceiling?
Yes — walls and ceilings indoors are both listed uses, on plasterboard, plaster or concrete.
