Questions and Answers for Loctite PL Door, Window, Siding 10 oz. Polyurethane Sealant White Cartridge (12 pack)

A:  It takes at least 24 hours to set up properly and longer if it is applied to fill a gap of more than about 0.125 inches. However, if it will only be a light rain a few hours after applying, it will likely be OK. If it will be a heavy rain where it will likely be hit fairly hard by the raindrops or be immersed in water, I would wait until it can remain relatively dry for at least 24 hours. It should also be noted that the area where it is to be applied must be completely dry at the time of application.

A:  It seems to work very fast. I had a leaky window frame so I applied it and it did rain a few hours later. It held nicely and hasn't leaked again. I really like this product for inside and outside on several different materials.

A:  Thank you for the question. There should be no adverse effect to the sealant under normal rain conditions. Vertical applications are not a problem, but horizontal applications could be if they become water submerged. It is best if the sealant can set at least 6-12 hours.

A:  You can apply it when it’s raining outside. Works immediately

A:  I would say about 24 to 48 hours to cure, might be rainproof sooner than that, somewhat depends on temperature

A:  I did, working so far (3 years)

A:  Thank you for the question. Yes, Loctite PL White Polyurethane Window, Door and Siding Sealant can be painted with oil-based paint when fully cured (in general 7-14 days minimum is recommended). Keep in mind some paints applied over flexible sealants can result in a loss of adhesion of the applied paint and/or coating, due to the potential movement of the sealant depending upon the scope of the project. Sealants are more flexible than paint. Because there are numerous formulations of paints in the marketplace, it is recommended you test for compatibility, adhesion and acceptable results before proceeding with the project.

A:  Yes, either oil based or latex paint can be applied to this product after it adequately sets up. However, I would give it at least a couple of days to set up before painting.

A:  I see no reason why not, but it might be difficult to color this product with stain to match the logs. However, if you have paint that is a very close match to the logs, this product can and should be painted after it sets up.

A:  Thank you for the question. It is possible with the understanding that sealing logs on a log home is a maintenance situation even when using backer rod. There are no guarantees on longevity with log homes

A:  I have used it on several different surfaces. I think it would be fine.

A:  I'm not an expert, but one of my best friends was in the log home biz back in the 80's and from what I gather the logs are always shrinking for years and then they still move a lot from season to season, so his company used to do a tongue & groove between the lower & upper logs but put a weather strip in the grove that filled in any areas that shrunk. Not sure if this is how you were going to use the glue, but as I said the surface area & large movements of the logs is way to much for glue to hold. BTW some times the sounds of the logs shrinking and cracking can sound like gun shots it's so loud. I would suggest going to the websites of current log home builders and see what they are doing today. Good luck!

A:  I believe this will work better than most other products to seal you RV windows and doors. Please also keep in mind that it will likely perform a bit better if it is painted after it is allowed to cure properly.

A:  I use if for that purpose and it works very well and has for several years

A:  I would not hesitate to use it on RV windows and doors. Please keep in mind that this caulk tends to perform better over a longer period of time if it is painted after it fully sets up in a few days.

A:  I would suspect it will hold. Only concern being the tenacity of the sealant s adherence to plexiglass. Door frame seals I'd bet yes. Try small then go big if successful. It is a robust product.

A:  Yes, this should work well on vinyl trim, especially in an exterior application.

A:  I would use it on vinyl trim if I needed to seal some areas.

A:  There is no reason why it would not, if one wants to use a sealant. It supposedly can move, plus or minus 35 per cent, as indicated on the product's TDS (technical data sheet).

A:  Yes, the item will work on vinyl trim.

A:  Yes, this sealant is waterproof.

A:  It is weather proof, not water proof.

A:  Yes, the Loctite PL Polyurethane Window, Door and Siding Sealant is water resistant when properly applied and cured. However, it is not recommended for underwater applications or permanent water immersion situations therefore it is not waterproof.

A:  Yes, waterproof. Great for Windows, doors, and exterior waterproofing..

A:  Yes it's waterproof and works great.

A:  in my humble opinion yes

A:  Yes, I believe so.

A:  If the posts are dry and not dirty. I would not use it on new posts that are wet from pressure treatment. For the stated application, I would try to use an outdoor latex caulk. This material 'may' work better, but it is definitely messy, requiring mineral spirits for smoothing out and cleaning up.

A:  Ken, This should be. Really good adhesion to pressure treated wood and it can easily fill the gap if you cut enough off the tip when you open the container. I do not know how smooth you need the finish to be, I have not tried to sand the cured product on my installation. When cured, this product stays flexible so you can tell it can move with the expansion and contraction of a substrate.

A:  It possible, but this kind of fix may only be temporary at best and may not look good from an aesthetic point of view. The splits are a natural occurrence in posts as they dry out and typically run with the grain of the wood. Some say that an exterior wood patch has worked for them but again it may only be temporary depending upon regional climate conditions. Unfortunately, there are no guarantees because there are no permanent fixes known. Loctite does not recommend filling splits with its products that run with the grain of the wood.

A:  No, the Loctite Polyurethane Window, Door and Siding Sealant will not bond or adhere well polypropylene plastic. We do not offer a product suitable for this type of application.

A:  Yes, I believe it will work quite well if I understand your intended application.

A:  Although, this is not an adhesive, it will seal very well as long as the vents fit reasonably tight to the foundation. If you need pressure to hold things together, this will not necessarily hold things in place while it sets up over about 24 hours.

A:  Yes, I believe that it will adhere to a wood surface that has been treated with a sealer. However, I recommend painting the caulk after it has been applied and has set up well after a few days. The caulk seems to perform better if it is painted.

A:  Typically caulks and sealants do not adhere or bond well to surfaces treated with selaers

A:  Yes absolutely

A:  It dries kind of slow, I would say about 24 to 48 hours depending on the weather, I waited a week. The instructions say "tack free in 15 to 30 minutes, Sealant skins within 24 hours, is functional within 3 days and reaches full cure in about 1 week

A:  I do not see this information on the Technical Data Sheet but it does say "Sealant skins within 24 hours, is functional within 3 days and reaches full cure in about 1 week." To be safe I would wait the week!

A:  The PL Polyurethane Window, Door and Siding Sealant should not be painted until it is fully cured. Cure time can be 7 days or longer depending upon temperature, humidity and volume of sealant used. Painting too soon may cause pigment separation with some type of paints or a tacky surface.

A:  24 hours

A:  I would wait a minimum of 24 hours. However, it would likely be better to wait about 48 hours. If you need to fill any large gaps, this polyurethane caulk can take two or three days to set up completely.
