SIKA – PU expanding foam spray – SikaBoom AP – Single component polyurethane foam – Fast curing – HFC-free – Easy to apply – 250 ml – Light Yellow

Applied it on plastered wall and door frame. Plastic surface won't hold the adhesive.My door frame was completely damaged due to moisture. Sprayed this product on complete frame and hence the dirt on nozzle that is seen in the picture.The fully cured product feels like thermocol.Lesson learnt:Allow the product to dry 100%. It should feel like rock to touch, only then slice (and not pull) the excess from outer edges.If the cervix is deep, then it takes about 30 to 40 mins to dry.The nozzle can be cleaned once the foam dry to touch as this product doesn't stick to plastic.A little goes a long way. No need to spray until we see the peak of foam coming out of the cervix as the nature of this product is slow expansion.Wear gloves during application else taking the product off the skin is a nightmare.I wish the nozzle was much slimmer.

It does what it's made for.But you should know this:- I runs out very quickly ( For me I used it to fil the whole window frame gaps and a lil bit on 3 places and that was it)- once you start using it, it'll keep coming out. You must do something to stop that.- MUST WEAR GLOVES to use it.- Use thinner (Acetone) to clean it off your skin off if you get any.

Best product. Nice performance. Chemical expands very well but you have to wait for 15 min so try with small amount and see how much space it covers and then decide to apply quantity. Doing this you will not waste chemical unnecessary expands outside the required place.ULTIMATELY PRODUCT IS VERY GOOD. 250 mL will cover approx (may be little less cover)1ft x 1ft x 1ft box area.

3 stars only cause once opened you have to use it right away and can't shelf the can. Also cut or scrape once the foam has dried.

Product came open with broken nogle with damaged pipe …no return policy west of money

Great product! It expands nicely and seals gaps effectively—perfect for small home repairs like sealing around AC units or cracks in walls. The foam sets quickly and feels durable once cured. Very easy to use, just be sure to wear gloves. Overall, a reliable and handy solution for DIY fixes 👍 Highly recommended!!

The product is very good but the quantity is very less

Product is good but cannot be used for 2nd time, since the nozzle and pipe supplied are fit for single use only. For me half of the can left post usage and don't know what to do.
