Transparent Waterproof Coating, TUFINEIN 35oz Invisible Waterproof Agent Indoor & Outdoor Sealant Water-Based Clear Sealant Roofs, Walls, Garden, Terraces

I thought I was going to have to tear out my shower tiles but no--I applied this coating, one coat, in the joints of my shower wall/floor and where the cracked caulking was letting shower water seep through, this waterproof coating sealed it up nicely--no issues.

First time to use this. Applied to brick and mortar surfaces. Easy to apply and works well to repel water.

Worked great on an exterior porch deck thats partially under cover and served its purpose

Easy to apply. Don’t put it on too thick as it will crumble.

I wish I had found this sooner. Great product that almost glides onto your flooring. Clear, smooth and adding a finishing look to my wood flooring.....I'm impressed. Thank you.

Great product recommend to other customers. Makes items leak proof.

I bought this product to provide a good water tight ceiling when making a sign for a friend. I found it did a really good job at ceiling however, there’s a lot of cleanup you have to do after you put the coats on because it tends to beat up quite a bit on edges. I haven’t completed evaluating it after a year but so far four months into Oregon’s winter weather it’s holding up well, but it did not seal in the stainless steel bolts very well.

I bought this TUFINEIN waterproof coating to solve leaks and the result was very good. It is totally transparent, does not change the color of the surface and leaves a clean finish. I applied it indoors and outdoors and so far it has withstood water very well. The application is simple and yields a lot. After drying, the waterproof effect is clearly noticeable. I liked that it works on different surfaces such as concrete, walls and ceilings. For the quantity and quality, the price is reasonable. I would definitely buy it again and I recommend it for those looking for a practical solution against humidity and leaks

Prodotto eccezionale — sigillante davvero efficace! Ho acquistato il Sigillante Impermeabile Liquido 1 KG TUFINEIN per risolvere alcuni problemi di infiltrazioni su terrazze e balconi, e sono rimasto molto soddisfatto del risultato. Punti di forza: • Facile da applicare: la consistenza è buona, si stende bene anche con rullo o pennello. • Ottima aderenza: aderisce bene a cemento, pietra, calcestruzzo e superfici murali senza screpolarsi. • Effetto impermeabile reale: dopo averlo applicato e lasciato asciugare correttamente, non ho più avuto perdite né assorbimento d’acqua. • Resistenza: il film creato è flessibile ma robusto, sopporta bene gli sbalzi termici e le fessurazioni minori. • Quantità giusta: 1 kg è sufficiente per una copertura discreta su piccole superfici o per interventi puntuali. Consigli utili: • Assicurati che la superficie sia ben pulita, asciutta e priva di polvere prima dell’applicazione. • È importante rispettare i tempi di asciugatura indicati in confezione, applicando almeno due mani se necessario. • Per superfici molto ampie o con forte esposizione, valuta un’aggiunta di rinforzo (rete) prima della stesura finale. In sintesi: questo Sigillante Impermeabile Liquido TUFINEIN funziona davvero come promesso. Se cerchi una soluzione affidabile per sigillare superfici soggette a umidità o infiltrazioni, te lo consiglio senza riserve!

Great product, it’s the only thing that we found that sealed a leaking shower for good. Be patient and use more than one coat if needed. It worth the extra effort.

Lässt sich gut verarbeiten, wie es wirkt und ob es die Feuchtigkeit zurückhält weis ich noh nicht

Tout est parfait

Acheté le 14/10/2025. Application récente sur de petites reprises d’étanchéité (supports propres et secs). Le produit s’étale facilement au pinceau/spalter, tire bien et devient transparent au séchage. L’odeur est faible et la surface garde un aspect discret (pas de voile blanc chez moi). Après 2 couches croisées, l’eau perle correctement et ne s’infiltre plus sur les zones traitées. Points forts Mise en œuvre simple, nettoyage des outils à l’eau. Film clair après séchage, discret visuellement. Pouvoir perlants satisfaisant sur petites réparations. À savoir / conseils Bien dépoussiérer/dégraisser et laisser sécher le support. Deux couches fines espacées du temps de prise meilleur résultat. Éviter l’application si pluie/humidité ou support encore humide. Pour grandes surfaces ou fissures actives, prévoir un renfort (bande/fibre) ou un système plus technique. Pour réparations localisées et joints à reprendre, c’est efficace et propre, avec un vrai rendu transparent. Satisfait du résultat pour l’instant.
