Excellent for campervan
Great adhesion and sealant, perfect for sticking campervan batons and really all things camper. I tested this by laying a piece of 2 x 1 on van metal floor and came back the next day to see what it would take to pull it off. Well it took about minutes bashing it with a hammer and edge tools. It was really, really stuck on there. Where i could used this stuff and screws for absolutely going nowhere fit, especially if anything was being mounted.

Always a reliable brand
Had to remove and replace an outside awning light on our motorcaravan and needed to remove the old adhesive and then reseal. A quality durable product which ensures a waterproof adhesion without messiness leaving an invisible finish. Sika products are always reliable and offer value for money

Great product need better packaging
Great product but packaging needs to be more protective - the nozzles had snapped off which doesn't affect useage but one was also missing from the pack of 4 purchased.

Great for resealing caravan
best sealant for caravan, I have done around the windows and have seen no damp in there at all. Even done the shower floor and it has worked. Application is easy and spreads nicely, Takes about 30 minutes to dry, Smooth out with finger and your good. Seems to hold very strong.

Perfecto: sella, pega y cunde. Lo caro no es tan caro cuando realmente es bueno
Estuve a punto de comprar otro sellador más barato, pero leí que era importante sellar partes de la autocaravana con un producto específico. Me pareció caro, sobre todo porque necesitaba 4 de ellas para sellar toda la autocaravana. Al final me ha sobrado más de una: cunde mucho, sella a la perfección, pero además pega, resiste el agua (por supuesto) y rayos UV, es limpio y se maneja de maravilla. Ahora me parece hasta barato. Muy recomendable si quieres sellar y proteger tu autocaravana, caravana, camper, etc..., del modo adecuado.
