[@grahamshillingford8229]

Without doubt the best brand of sealant I've used is Dow Corning. Any of its range which is huge in application type and colour. Soon as you pick a tube up you can feel the weight of it. I've been using it for over 30 years & most installations are as good now as they were when they were originally fit.

[@matthewgartell6380]

Best silicone you can buy. Mapei does some good stuff but Dow corning you can use on anything

Thanks a Roger - lots of great info here on a confusing topic. A great tip regarding the filler rod, which makes total sense (and I never knew existed!) - how many times have we seen silicone which has come away from one surface, as it can’t stretch? Great channel and delivered in a way which is educational, but is based on real world experience. (I’ve just watched the episode where the bifold doors were made the wrong size and glad this sort of thing doesn’t just happen to me!)

[@studebaker4217]

I happened across this rod thing browsing a US hardware shop years ago. They called it caulking foam I think. Still got some left in different diameters, it's been very handy.

I maintain an old Victorian building and have done for about 20yrs and I’ve used SX lead pointing sealant on some of the cracks in various places on the masonry and found after all that time the sealant is still in good shape. I’ve used other lead pointing sealants and they’ve been rubbish.

It would be interesting to find out what its made of to ensure I use the same chemical composition in the future. Cheers

Funny, I was in screwfix other day thinking what's difference between silicone?

This stuff, whatever it is would be well handy in the building trade.

[@mattyboy3908]

Brilliant Roger, finally a guide from someone who knows what they’re talking about on the different silicones out there. Funnily enough I tried Dow Corning 785N neutral cure in a shower last year and 12 months later it was black with mould. Never had that problem with standard 785 acetoxy, perhaps it was a duff tube. And in all my years on the tools I can say I’ve turned my back on gripfill now, more hassle than it’s worth, I find the stuff unusable for most jobs as it skins so fast, as you say you have to work it and pull it off then reattach. Not ideal, especially when fixing long lengths of skirting

I find exactly the the same. I started using pink grip. What do you find best? Got some skirting going on this week.

Great video. Who would have thought that sealants were so complex. You mentioned your campervan; may I ask what brand of sealant you would recommend using on the exterior of a roof skylight. Thank you

[@timothygange1185]

Sikaflex 522 is UV a UV resistant, fungicidal treated polyurethane that's super strong. It's the replacement for 512. I used 512 on my roof vent and it's really good. You want to mask off well to get a neat joint because once it touches a well prepared surface it really doesn't like to come off. www.uksealants.co.uk/sikaflex-522-caravan-sealant-adhesive.html

Hi Roger. Hope you are well. I am renovating the house and learning a lot from the videos from Skill Builder. Really concise and informative. May I please ask a question Roger - I have bad cracks between Staircase skirting board and the wall. I had one of the local decorator come in to solve the issue. He has put some expanding foam between the gaps and them some caulk. However it looks like using the stairs has caused some flex which cracked the caulking. I am looking to reapply the caulk and was wondering what caulk would your recommend for the same? Watched few videos and I am inclined towards using Evo Stick Sticks Like White Turbo (I understand this an adhesive but can be used for this purpose). The cracks looks horrible and hence looking to sort this. Thanks in advance.

[@Messimagician83]

What would be best to product to use for the following items? Stainless steel splashback Acrylic perspex panels Top mount sinks

[@fxbootstraps]

[@SkillBuilder]

Glad to hear that

[@PWN_Nation]

Roger - another facet of "stuff in tubes" can be 'paintability'. So many clients have tried to paint silicone, with zero success most times. And, of course, once a substrate has been covered with silicone, it makes it nigh on impossible to get paint to adhere.

[@SkillBuilder]

Mitre mate two pack. Spray one onto the case and put some drops from the bottle onto the hinges.

[@jonthomson1996]

Great video Roger, but I must take issue with you regarding High/Low modulus sealant. Your description is quite correct - High Modulus sealant will form a stiff bead whereas Low Modulus will form a flexible bead. The important consideration is the relative strength of the bond onto the substrate and the amount of anticipated movement. Partial de-bonding as you described helps if the substrate bond is strong but if it is weak then only low modulus sealants are going to survive. If you look at concrete structures you can see movement joints which will have been sealed with high modulus sealants and, typically, either the substrate bond will have failed (and just pulled away) or the substrate bond is so strong (because it was properly prepared) and the surface of the concrete has been pulled off. A failure in either case.. Fortunately the good manufacturers provide advice on joint design which is worth following. Also, if they say you need a primer - you will need a surface primer to ensure good adhesion.

[@SkillBuilder]

Thanks Jon. That explains it a lot better. I will return to the subject. Do you fancy a Zoom call on this?

[@academicmailbox7798]

@@SkillBuilder Roger, in connection with concrete substrate. In relation to bituminous roof products, like 'Parlon' sheeting etc. So like to drill holes for various attachments. And fill around after, using silicon tubes and things. You can quiz they guys who do the bituminous based roofing products on this. They have their own bituminous based mastic products. For this purpose.

[@academicmailbox7798]

Electrical trades, roof based air handling, air con, mechanical trades. When one puts silicone based mastics and things. To 'seal' the penetration around bituminous based roofs. The two will react, and you end up doing. More harm than good. I'd put this in with that same point. On the concrete substrates.

[@academicmailbox7798]

Metal workers too. Have to go on roofs. Make handrail systems and all kinds of things. Drill holes through vertical parapets made of concrete. To which bituminous (or other roofing systems have been applied as upstands around roof edges). I've spent weeks up on roofs. Moving packaged air handling units around. And this is something, that really deserves it's own 'health warning' video. On it's own. What is the roof made of? Synthetic (chemical welded seams, where one can buy specific patch kits, and things to make penetrations and seals). Whereas bitumin is different. It's an ancient, natural type product. Which works a lot different to synthetic versions. In terms of roofs.

[@academicmailbox7798]

Bitumin is a good system, if you have a good contractor. But even that guy can't prevent the spark, or the air con tech or whoever comes along after. With a drill and a tube of stuff. Where they don't even know difference between natural bituminous or man made roofing materials. I'd imagine too. The point about low modulus products on concrete substrate. Is relevant to that situation in question. Where it is a penetration through a Parlon roof product. Sheet metal trades, who go over parapets with coping metal flashings. At the top of their glazing and cladding systems. At roof level. Regularly don't understand this either. And drill down vertically. At the top of parapet walls. To make anchor screws for brackets or straps. To which the pressed sheet metal copings. Will clip themselves on to. Is another place where guys use silicon on bituminous finished concrete on roofs. Where a long life, flexible seal using a bituminous roof sealant tube. Is what is needed in the hole. When putting in those anchor bolts.
