Best polystyrene glue

Updated: 23 October 2026

A single best polystyrene glue list is how a foam contact tube and a kit cement needle bottle get treated as rivals. They are different products that happen to share a search word. You want a top pick and a best value for the job in front of you, and a clear reason to walk away. This page names those picks inside the amazon.co.uk set on our [polystyrene glue comparison](/hub/fillers-adhesives-and-sprays/polystyrene-glue). Prices are the 19 October 2026 listings, in GBP. Peter F. checked the listings and maker sheets. We did not run a lab test. A qualifying purchase can earn us a commission at no extra cost to you.

Pick the job before the ranking

There is no strongest polystyrene glue in this basket. Stars alone would hand the decision to a 120 ml bottle at 4.8 from five ratings, or to Contacta's 13,778 reviews when the part in your hand is white foam. The highest score sits on UHU por 50 ml, £6.75, 4.6 from 847 reviews: the documented foam contact adhesive with a real UK review pattern. Best value is the UHU POR twin pack, £11.82, 4.7 from 57, the same chemistry when you need volume. Contacta Professional, £6.47 and 4.5 from 13,778, is the reviewed kit cement. Aleene's Felt and Foam, £12.99 and 4.4 from 1,860, is the reviewed tacky gel. If you have not named foam, hard kit styrene or felt, start with the polystyrene glue buying guide.

Best foam contact adhesive in this set

For expanded polystyrene, foamboard scenery and RC foam, UHU por 50 ml is the top pick. Reviewers describe bonds without the melt pattern of ordinary solvent glue when the contact method is followed, and a flexible clear film on foam that flexes. The listing names hard foam such as Styrofoam and prints a waterproof colourless film. The paste is greasy, and at least one UK review still reported foam attacked. The twin pack at £11.82 is more volume, not a different chemistry. Its cure field is twenty-four hours; the single tube prints twenty minutes. Do not blend them. Skip both for polypropylene foam (EPP), plastics on the exclusion list, and wall insulation boards. POR is highly flammable. Foamboard and Depron detail continues on polystyrene glue for models and RC. WAN2TLK and LAMXIN, both £12.99 for 120 ml with five and six reviews, stay as scrap-test bottles.

Best kit cement in this set

For hard polystyrene kits, Revell Contacta Professional is the clear pick in this set. The needle places a small amount on a joint, reviewers say a little goes a long way, and the listing names plastic with a welding effect. Full cure on the page is twenty-four hours, and the pack is not water resistant. The needle clogs and can pull out with the cap. Skip Contacta for every foam job. The review count is evidence for kit building, not for expanded polystyrene. If the canopy or clear part fogging risk worries you, that is a solvent-cement caution, not a reason to put the same bottle on Depron.

Best felt-and-foam tacky glue

For felt trims and soft craft foam, Aleene's Felt and Foam Glue is the pick with a large UK review file. Reviewers who like it describe grab on felt, little bleed-through and a flexible dry film. The maker names STYROFOAM brand foam and felt, about an hour before handling, water resistant, not washable, and non-toxic on the maker's own page. Other UK reviews say the gel never grabbed, left wet marks, or needed a hard squeeze. Listing colour is white; some reviews disagree on a clear dry film. Skip Aleene's for washable toys, kit welds, and RC foam that needs a contact adhesive. The 120 ml bottles that name EVA are scrap-test only beside a 1,860-review felt file.

When best is outside this comparison

Skip every craft tube here for EPS or XPS insulation boards on a wall or roof. That is a board adhesive, such as a solvent-free polyurethane, not a 50 ml hobby tube. Skip them for unmodified polystyrene ceiling tiles under Approved Document B; the adhesive does not make those tiles acceptable in new buildings. Trade POR tins, named board adhesives and specialist canopy glues are outside this amazon set.

Common questions

What is the best polystyrene glue for Styrofoam or foamboard?
In this set, UHU por 50 ml. It is the foam contact adhesive with the deepest UK review pattern. Use the twin pack when you need two tubes of the same chemistry. Neither listing is a wall-board adhesive.
What is the best polystyrene glue for plastic model kits?
Revell Contacta Professional. It is a solvent cement for hard kit plastic, not a foam glue. Buy it for the needle weld, and keep it away from expanded polystyrene foam.
Is the product with the most reviews the best overall?
No. Contacta's 13,778 reviews make it the best-documented kit cement in this set. They do not make it safe on foam. UHU por's 847 reviews beat a 4.8 from five ratings on foam duty.
Which listing is best value?
The best value is the UHU POR twin pack at £11.82 when you already want POR and need volume. The single 50 ml tube remains the top pick for a first foam buy with the larger review file.
Should I buy WAN2TLK or LAMXIN as the best foam glue?
Not as a default. Both sit at £12.99 with five or six reviews. Scrap-test them for EVA or foam board if you want, and keep UHU por as the documented foam contact adhesive.
Is Aleene's better than UHU POR?
Only for felt-and-foam craft where you want a tacky gel. It is not a substitute for POR on structural foam scenery or RC foam that needs a contact film, and it is not washable.
